If You're On The Fence About This Radio, Watch This

Rlaarlo sent me a new 8-ch radio to test and review. I've spent about 4 hours using it before I even started to make this video. I wanted to understand it well so there were no surprises later!
First, the radio looks familiar because it is already on the market as the HotRC CT-8a (gyro-enabled receiver not included but available separately). Buuut this one has Rlaarlo firmware and quite honestly, a very compelling feature set for a crazy price. Even the spare gyro-equipped receivers are roughly DumboRC money. That's rather impressive, yes?
So yes, Rlaarlo CT8a and HotRC CT-8a look the same because they're from the same company. But don't let this put you off; Rlaarlo is all about their cars - and what a year they've had! Their new CT-8a 8-ch radio system is running Rlaarlo firmware and is ready to install in your favorite RC model from any brand. Oh, it has a gyro AND mixing AND multiple power sources.
It looks great on paper! But I'm typing this with an injury after testing the system for about 24 hours now. So, let's see what it's actually like to use.
If you're convinced, buy one here:

Extra Receiver:

Notes:
- I haven't been able to get the gyro to work correctly yet. Still working on it.
- not all 18650 batteries fit. I cover this in the video.
- make sure you don't buy their DumboRC receivers if you want extras, as they won't work with this radio.

[@bongofury3176]

been using this radio for 2 weeks with a Flux RX and a Muraco. I rate it. really responsive. swapped wheel for metal radiolink style with small spacer to keep away from main body. tiny round N52 magnets are the best thing for adding a button top to a flat top battery

[@RCTNT]

Oh, that's so obvious!! Lol thanks for the magnet idea, that's gold! Glad you're enjoying it 😊 I've been using it with my Bandit this week after further mods and it's been very good. I'm loving the voltage monitor in particular, it's really useful.

[@Noizy-Boy]

Hey Craig! I really enjoyed watching you review that radio. It's a very interesting radio to me. The functionality of that radio at that price is truly amazing to me. I want to get my hands one and will... in a few short weeks. Once I saw the price AND you got a cut on the sale, I was all in! Thanks, mate, for the great info! 😎

[@RCTNT]

Awesome. Yeah it's a good deal with the gyro in particular eh. Thanks!

[@muskokamike127]

Oh yeah, Merry Christmas to you and the fambly as well! Looking forward to more vids in the new year.

[@RCTNT]

Thanks Mike, and to you. Been good talking this year eh. All the best.

[@santommaso6740]

Best Review i saw ⭐️ i Order a 18650 battery with a higher plus pol, its important to Know and Show this, good Job 👍looking for your next Video about How to Update Firmware

[@RCTNT]

Thanks! I'll share an update once there's new firmware. Cheers

[@FrankvdBerg]

Got this one as well. And i have to say its amasing. The range is perfect for basing and its nice and light. Also a good grip. Yeah like it a lot

[@RCTNT]

I'm pretty happy with it too. It does chow their AAs though, so a lithium based power source seems to be preferable!

[@FrankvdBerg]

@@RCTNT yeah. AA does work for half an hour. And it cuts off to soon. But i now use 2s lipo. And that makes a big difference. Only thing i found is that the receiver is a bit big so it doesnt fit the Arrma reciever box. But i put it on its side and then it fits. But offcourse the giro doesnt work that way

[@RCTNT]

@FrankvdBerg hm yes that's also a challenge. I think I might look into conformal coating for the board on my second receiver, which arrived 8 days after I ordered it. Then I won't need to use the rx box and water won't be an issue. For the price, I'm still happy. But I do think AAs are so poor in this thing that they really should suggest lipo as the recommended power source, so people have that expectation. I'll touch on this again when I do my radio system round up later this year.

[@FrankvdBerg]

@@RCTNT maybe in the future there will be smaller receivers.

[@RCTNT]

@FrankvdBerg I haven't checked yet but maybe hotrc already has them. They'll probably work. I'll look later and test if I can find one.

Great channel bro, always bring good content Thanks for your hard work!

[@jorgep40]

Thank you for the review. I've been enjoying this remote a lot so far the only thing I haven't figured out is how to turn my lights on and off, it's on my traxxas 2wd slash, I have the lights connected to channel 3, I'm going to try what you did see if it works for me

[@RCTNT]

You need a light controller or a remote switch between the lights and the receiver. If you plug them in directly they'll just be on. This kind of thing: amzn.to/3vlHhHB

[@bartbbb1046]

Just checked their website, the price for such a transmitter is insane! And receiver at 9.99 USD, this can be a very option for a basher radio system.

[@RCTNT]

Impressive for a gyro equipped system that also does mixing eh!

[@cwthemachinist]

Seems like a pretty nice radio. I really like that other companies are coming out with good radio systems and giving us options besides Spectrum. I.M.O. Horizon has kind of ruined Spectrum radios. Nice overview video you made of this new system. Merry Christmas to you friend, from the Great White North of the USA, here in Northern Maine!

[@RCTNT]

Thank you, and agreed! Merry Christmas to you too, and thank you for watching my videos this year 😊

[@armandutan5901]

Hi, I bought the HotRC version and my first take is that the main difference between Rlaarlo and HotRC is the gyro receiver, the availability of the standard CNC wheel and comes with 16850 battery standard. All HotRC receivers are not waterproof (and I wished they are). I have not install it on any of my cars yet so I do not driving review. My biggest irk of this transmitter is how fingerprint magnet the surface is. Otherwise, it is compareable with all the midrange offering from the major brands. Cheers - from Indonesia

[@RCTNT]

Hi Armand, that's good info, thanks. I've tested with the gyro and it works well. Wish it didn't drain power so fast though! A good 18650 is important with this transmitter. Cheers

[@armandutan5901]

@@RCTNT I purchased 4 (3 sponge and 1 cnc) of them but I wished I purchase all cnc because the sponge made the tx felt really cheap. So I am keeping the CNC and selling the sponge(s) instead 🤣 The 18650 (my apologies, I always got the number mixed up) I received for all 4 are 1200 mah. Somehow I could not charge them directly so I bought an external one and it takes forever to fully charge them. Perhaps I bought the wrong charger 🤷🏻‍♂️.

[@RCTNT]

I didn't even notice the typo with the battery! Have you tried usb cable charging of the radio? It might not actually charge if the radio is off - or, it could be faster if it's on. It's a bit weird, I've found this also. But it does charge, just gotta leave it overnight.

Radio is fine but can't get over we won't have more RC TNT this year...😢

No more before Christmas at least but there'll be more. It's a very quiet time for youtube. My last two videos between Christmas and new year bombed. I've got a drive day that'll publish between Christmas and new year so I'll catch you then!

[@jrfishes]

I use Enloop Pro's in my radios as well. Don't understand why some folks use throw away batteries.

[@RCTNT]

Indeed. I'd really like to see RTR rigs stop coming with the disposable batteries. Good for convenience but it adds up.

[@insanebmxthomas]

great looking controller for that price :o i kinda wonder how they even make a profit on this! really enjoying my Rlaarlo desert buggy! Not only are they affordable, but the quality seems great as well!

[@RCTNT]

For sure they will be making money on this. But it's still a stellar deal. (I was driving my AM-D12 the other weekend, too! Top little goer isn't it!)

[@insanebmxthomas]

@RCTNT yeah it is a blast, even though i need to order tire glue after 3s. 😆 Going to try a very lightweight mod to combat ballooning. Whats also cool; we were out in the rain. My friends hyper go infraction on wet asphalt; totally wet inside. Mine, going 50 through grass and asphalt, 2 packs, dry as dirt! No complaints here!

[@nicohoshino692]

40 USD is a bit expensive compare to the hotrc ct8a which i bought from TaoBao{Chinese version of aliexpress), 1 transmeter + 2 receiver cost me around 40 AUD, even though the hotrc version doesn't have the dyro but its cheaper, and basically the same thing

[@RCTNT]

If you need a gyro and mixing, this price is exceptionally good. If you don't need a gyro, there are better options, sure.

[@mattmays9063]

Hold up, a decent 8ch radio. I've legit been shopping for my last Radio with all the features I'd like, and I've seriously been floating around 2 or 3 different radios without being able to make a decision for 2-3 years now.

[@RCTNT]

If you want 8 channels, there's a lot less choice than 6 channels. The HotRC CT-8a is a rare and excellent choice, but the Rlaarlo version here gives you all that AND a gyro. It's pretty epic eh!

[@muskokamike127]

Yeah seems like a really nice transmitter for $40 USD.

[@RCTNT]

Yeah, I thought so!

[@robertgoldsmith5949]

I just got mine in the mail. It’s got a beautiful operations manual, but I don’t see any instructions about how to install it. Trying to follow that from this video but I should have something in writing.

[@RCTNT]

What do you need to know? I can give a few pointers: Install it flat if you intend to use the gyro. Orientation doesn't seem to matter otherwise. It follows the universal schema of steering on 1, esc on 2, then subsequent channels as marked on the controls. Battery voltage sensor cable goes into the balance lead on the 1st and 3rd (2s) or 1st and 4th (3s) ports. For absolute maximum radio range, ensure the last 4cm of the antenna wires are straight, upright, at 45° from horizontal, 90° from each other - that's an upright V, basically. If you don't need max range, simply keep the wires separate from other cables in the car and try to keep the last few cm straight. Hope that helps!

[@gigi_lu_bolong]

How do you solve the CH2 Trottle moving by itself?? greetings from Indonesia

[@RCTNT]

Oh, it's been a while now. I think I looked at the manual for the esc for throttle calibration and did that procedure. It worked.

[@gigi_lu_bolong]

@@RCTNT the number on the ch2 throttle sometimes moves by itself.. so the car sometimes drives itself. it should be at 1500. but this number moves by itself

[@RCTNT]

Whoa, I see. That sounds like a fault with the potentiometer on the throttle. Contact rlaarlo for help.

[@njd879]

Great video, thanks. After purchasing I finally Got around to setting it up recently but I can't get the reverse to work. Can you help me with how to set up reverse? Thanks

[@RCTNT]

Reverse works out of the box. You need to calibrate the throttle input on your esc. Check the manual for your esc, look for Throttle Calibration or similar

[@njd879]

Thanks, you were right it was my max 5 esc I needed to recalibrate. Thank you!

[@RCTNT]

@njd879 great! Glad it's sorted 😊

[@paulwells3271]

please tell evryone there is no trim buttons for on the go driving and when trigger grip is fully or even part open reverse is hindered

[@RCTNT]

I think we covered the trigger grip thing. You can always remove it, but I tested it on camera (unless I cut it in the edit?) and didn't have a problem with reverse. It sounds like removing it might be the way to go for your preference. Trim: it didn't occur to me to check that. I've since used this radio in two other models and it still hasn't come up, but I can definitely see how that would be annoying if you use it regularly. Thanks for noting it. I think my biggest criticism of this radio is how power hungry it is. I'm waiting on delivery of an 18650 Samsung q30 but I suspect a good lipo is probably the way to go. The radio isn't perfect but for the money I still reckon it's pretty decent. Hope you're enjoying yours, despite the trim and trigger complaints!

[@paulwells3271]

it is a very good controller for the price but I find at the moment everything I've had from them has been good in the making just bad in the build.would love there cars to be in kit form

[@RCTNT]

@paulwells3271 a kit would be cool, yes. I used the Rlaarlo radio last night to see if I was still happy with it. I am, and I even got the gyro to work properly. The UI needs work but it's decent enough, especially for the money. Anyway, yes, good point about execution. You're right.

[@Mick_Au]

Hey mate looks and sounds good. Im interested as Im now up to four vehicles in my collection and would to not have to worry about taking a controller with me for each one. Im still very much fresh in the hobby so dont know a great deal. Just a question who do they use for shipping??? If i cant get it posted using aus post at the end it makes it much harder to receive for me. Cheers

[@RCTNT]

It probably varies. As you can imagine, I receive a lot of goods from hobby places, both purchased and sent for review. I have trouble with couriers where I am too, and given I'm semi-rural, we need to go to the post office to get our stuff. Postie doesn't come here. For what it's worth, all the Rlaarlo stuff I've received to date (7 or so vehicles, multiple parts and accessories) have all been waiting for me at the PO. But I don't know what carrier they chose to use, sorry Mick. I will also add that if the cars are adding up and you want to use a single radio, this may not be the best choice unless you specifically want a lot of channels, gyro and mixing. There are two other models to consider that will be a bit cheaper and offer better battery life because they're not powering a big LCD screen (which is gorgeous, don't get me wrong, but battery life will suffer due to the extra power needed): 1. FlySky GT5 with BS6 Rx (has gyro): asiate.es/aff?l=150074&i=76070 (aff. link, FYI). Additional FS-A3 receivers are $10 or $15. Gyro receivers are roughly double that. This is my favourite radio system. I have 4 of them. 20 model memory, button, 3-pos switch, 2x dials, good on battery. 2. DumboRC X6: www.amazon.com.au/KAIMIO-6-Channel-Transmitter-Receiver-Controller/dp/B0C4T6BPN8 - comes with a gyro Rx and additional non-gyro receivers are $15 to $40 depending where you buy. Unlimited model binding, but no memory, so you set trims each time you bind a new model.

[@Mick_Au]

@@RCTNT Wow thanks for the detailed reply mate much appreciated. Will sit down and have a good look at them while I have some time over the Xmas break. Many thanks 🙂👍

[@mightymanny7207]

Thanks for this video, would you recommend this for a budget Touring racing build?

[@RCTNT]

This or DumboRC with X6FG receiver (it you want a gyro). The nice thing about the Rlaarlo radio is the gyro is adjustable. I wish it wasn't so thirsty on power - this radio is otherwise pretty much perfect for a cheapish one.

[@mightymanny7207]

@RCTNT Thank you, I am slowly getting into Touring RC racing and I'm searching for a low cost transmitter suitable for beginners. I was interested in the DDF-350, another question. Do you use gyros when I comes to RC racing?

[@djh254]

I’ve noticed when using mine with AA batteries it cuts off intermittently and the 18650 do not fit…. Love the radio though otherwise…. Also does it charge the lipo 2s via charging cable?

[@RCTNT]

I'm still looking for a good solution to the 18650 issue. Charge port is only for 18650.

[@paulwells3271]

mine does the same AA battery just shuts down so it is a problem

[@RCTNT]

Yeah power has been an issue. A quality 18650 is probably the way to go. The pink Samsung 30Q I showed on camera is a good choice, though mine are well used and I suspect a newer one would be longer lasting. You do need the foil top on it to make contact with the battery lid though. This is a design oversight. The AAs I'm using with some success are the Panasonic Eneloop Pro (the black ones). They last pretty well.

[@santommaso6740]

Can I control a color-changing LED strip using a remote control?

[@RCTNT]

Sure can. Something like this is required: s.click.aliexpress.com/e/_DFPtOkL

[@santommaso6740]

I bought this exact one. The color change works with the remote control, but it doesn't save the setting when I turn it off. What am I doing wrong?

[@RCTNT]

@santommaso6740 nothing wrong, that's how it works. Doesn't have memory. Changes based on switch inputs. Without a nicer led controller (I don't know of any), that's how it's going to be. Could design a better controller with arduino though, I'd expect. You'd make a simple sketch (program) that would sit in-line with the LED controller and intercept the signal (using the servo.h library). It would save that state to memory. It would work by sending the inputs to the original LED controller to change it to the last mode you used when it's powered up. Then any changes you make get saved. I haven't used this LED module before, but let's say it has 5 colors you cycle through. Maybe there's a mode setting for on, blinking, strobe, chaser, too - I'll ignore that for now. You want the third color most of the time, let's say that's blue. 2 presses from when it's on gets you to blue. This module will read your two presses and save that state. If you make no further inputs on that channel, next time you power up the car, it'll wait a set amount of time, and then send 2 button presses (PWM signals) to the LED controller, changing it to blue. Easy enough! I'll put a sketch together for you. Give me a few...

[@RCTNT]

// RC-TNT Quick'n'Dirty RC LED Automation // Works best on Arduino Nano #include #include Servo rcChannel; // Servo object to read the RC channel Servo ledController; // Servo object to control the LED controller const int rcChannelPin = 9; // Pin connected to the RC channel const int ledControllerPin = 10; // Pin connected to the LED controller const int buttonPressDelay = 100; // Delay between button presses in milliseconds const int startupDelay = 2000; // Startup delay in milliseconds const int numColors = 5; // Number of colors available const int eepromAddress = 0; // EEPROM address to store the last state int currentState = 0; // Current state of the LED controller unsigned long lastPressTime = 0; // Last time the button was pressed void setup() { // Initial delay to allow the system and LED controller to come online delay(startupDelay); rcChannel.attach(rcChannelPin); ledController.attach(ledControllerPin); // Read the last saved state from EEPROM currentState = EEPROM.read(eepromAddress); // Set the LED controller to the saved state for (int i = 0; i < currentState; i++) { pressButton(); } // Wait a moment to avoid immediate changes delay(1000); } void loop() { // Read the PWM signal from the RC channel int rcValue = rcChannel.readMicroseconds(); // Check if the button is pressed (assuming a press is indicated by a high value) if (rcValue > 1500 && millis() - lastPressTime > buttonPressDelay) { pressButton(); lastPressTime = millis(); } } void pressButton() { // Send a button press signal to the LED controller ledController.writeMicroseconds(2000); // Adjust the value as needed for your controller delay(buttonPressDelay); ledController.writeMicroseconds(1000); // Adjust the value as needed for your controller // Update and save the state currentState = (currentState + 1) % numColors; EEPROM.write(eepromAddress, currentState); }

[@RCTNT]

Note this line: const int numColors = 5; // Number of colors available - change this to match the module You change that number 5 to however many colors there are in the cycle. How it works: 1. Setup Phase: - Attach the servo objects to the appropriate pins. - Read the last saved state from EEPROM. - Send the necessary button presses to set the LED controller to the saved state. 2. Main Loop: - added a startup delay of 2 seconds to give everything time to come online. - Continuously read the PWM signal from the RC channel. - If the button is detected as pressed, it sends a button press signal to the LED controller. - The state is updated and saved to EEPROM. Adjustments Needed: - Pin Configuration: Ensure rcChannelPin and ledControllerPin are connected to the correct pins on your Arduino Nano. - Button Press Signal: Adjust the microsecond values in the pressButton function to match the requirements of your LED controller. - Color Mode Handling: If there are additional modes (like blinking or strobe), you would need to expand the state handling and possibly add additional button press sequences. This sketch should provide a basic framework to get you started. You can expand and refine it based on the specific behaviors and requirements of your LED controller. Download the software here: www.arduino.cc AliExpress sells Nanos. They're really cheap.

I got this a few weeks ago and its been great however i cant get the gyro to work. If i pick the car up and wiggle it the wheels turn so its working but when i place it on the floor and accelerator the car is turning in circles. Any idea what ive done wrong?

[@RCTNT]

I'm having a similar issue. Haven't made time to work it out yet, but I've fired one of the receivers to my Bandit and I just fixed that car yesterday, so I'll have a play and see if I can work it out.

[@RCTNT]

Ok, I've gotten it working nicely. In my Bandit, here are my settings for the gyro: Receiver is flat inside the motel. Car is flat on the ground when turned on, and not moved for a couple of seconds after. Gyro on Sensitivity 40% Direction cons Range 34% Seems about right. Can adjust sensitivity down further, if needed. I'd keep them both under 40% for best results.

[@kopigangrc]

Hi Craig. I've been wanting to purchase this transmitter, able to adjust the EPA for the steering? As compared to the LDARC CT? Both are budget friendly. Able to help me out? Thanks. And as always great video with awesome reviews. 😊

[@RCTNT]

Thanks for waiting for my reply. Been a busy day! Ok, so the EPA is definitely adjustable on the Rlaarlo radio (it's really a HotRC CT8 with Rlaarlo firmware and a gyro receiver) but my biggest gripe with the radio is the battery life. It's otherwise a fine machine and if you get it onto a decent quality 18650 or a 2S Lipo, you're golden. However, I'm not familiar with the LDARC CT, but it looks amazing. If it does mixing like the Rlaarlo does, then it may be a better choice. But if it doesn't, the Rlaarlo here will be far superior overall, IMO. Good luck with it, they're both pretty decent by the look of them! (And don't forget the FlySky GT5, that's a brilliant radio and additional receivers are really cheap if you just need 2 or 3 channels (FS-A3) or even if you need 6 (FS-A6 or FS-i6, among others). Cheers

[@kopigangrc]

@RCTNT Thanks Craig for the info. I do really find them useful. Yes, I do have the FS GT5 on most of my rig. Cos recently I got myself the D1RC D110 roller. Uses a whole lot of channels for lights and stuff. So I just thought of a budget friendly radio with lots of channels. And have a great 2024 with lotsa new rigs to review.

[@81quiroz]

How is the range and can you use a rc similar with it

[@RCTNT]

They claim up to 350m, but at an educated guess, you'll only achieve close to that if you mount the two receiver antennas at a 90 degree angle from each other, both upright at 45° from flat in the vehicle. Can you use an RC similar with it? I don't understand that question, sorry. You can put the receiver into and rc car that has an ESC to power it.

[@81quiroz]

@@RCTNT sorry what I meant to say can you use this with the simulator to practice online because I’m looking for a radio that I can keep for a long time I have four cars only and something that’s well built in affordable

@81quiroz ah, I see. I've read that you can do that with this radio but I haven't tested it. I'm really busy this weekend but I'll look on Monday and see if I can work it out for you.

[@Boogie_the_cat]

Flat topped 18650s are not made to be used like bump-top 18650s. Flat tops are made\sold to be spot welded into casings. You can't complain about a manufacturer not speccing their device to run flat top 18650s, because that is using the 18650 in a manner that is not supported by the manufacturer. Flat tops are not designed to slot into battery compartments. You can't expect a manufacturer to spec their products to use batteries in configurations not intedned by battery manufacturers. Those Samsung batteries suck by themselves anyway, they are used in large banks and thats why there is no button on top. You're using the wrong kind of battery and no manufacturer us going to design their products to use batteries improperly. a spring in the + terminal area would put uneven pressure on a normal 18650. It's unnecessary for users who use the correct type of battery. The end.

[@RCTNT]

Point taken. Thanks. I've been playing with 18650s for years and that didn't occur to me. It's therefore probably worth mentioning, given many folks probably will make the same oversight. I still think a spring in the top would be a simple cover-all, but fair enough. You're right!

Could be your esc needs to do that calibration, too. Look into that. You need to tell the Esc what your radio limits are. Check your Esc manual for "calibration".

[@RCTNT]

Ah I see. After looking into it, as far as I can tell, the E45A ESC in that car is a custom job that matches the radio the car came with. I'm not sure this ESC will work with another radio of any kind, unfortunately. It might, but I'm not confident. Sorry for the disappointing news. I hope I'm wrong!

Heh, that's a cool idea, the phone bit. There may be better ways to do control, but I don't know what that might be yet!

[@adamross4774]

Well... it's ordered... 🤞 lol this is my first transmitter... Just got into rc this year with a MJX h16BM soild little rig, and foaming at the mouth for my 2nd car.... an Arrma infraction 3s blx. Gona pick that up in a week or two! Like your channel btw 👍 ya help me decide on my purchase thanks!

[@RCTNT]

Nice one. I don't think I have either of those cars on my channel yet but I'm glad the radio one here was helpful. It's a great hobby, this. Hope you enjoy your new gear!

Mate if you like mixing i think you owe it to yourself to grab an MT12. Spent 2 hours setting up a full fat crawler, which is actually a lot more fun than it sounds. ELRS with a multi protocol module - truly one radio to rule them all. That being said 40USD is practically giving the CT8a away.

[@RCTNT]

I'm using mixing for some comp crawlers with various sanwa and futaba radios but I think my new one to rule them all is my flysky noble nb4 pro. 12+18 channels on a master & slave setup to run my 8x8 with its various bits and pieces and then a trailer with the slaved receiver to run all its features too. Numerous channels get eaten by mixing but it's a thing of beauty when it's all configured correctly!

@@RCTNT You know what, maybe a video explaining how you did that would be in order. I've been reading for some time now that using sbus or ibus or PPM you can expand your available channels beyond whatever the transmitter/receiver say they're capable of, but have never figured out how to do that. Maybe you could show us all how that works in practical real world terms? 12 + 18 sounds phenomenal, and I'd like to know how to do it. I bet others would too.

[@RCTNT]

Sure. I'll do a video on the nb4 pro and we'll cover this. Like the SCT comparison series that will end in a single video to tie them all together, I'll do something similar for radios. Am gradually building a library! Short answer is kinda two parts: 1. iBus will expand one port to numerous. The more channels, the higher the latency as there's more signal to process to differentiate each channel. 2. Mixing takes channels and often several, at that. Your 18 Ch system might only have 4 to 8 ports on the second receiver and that's enough. The rest of the channels are real, but virtual, being 'boxes' for the mixing functions to assign the individual roles that are then combined on yet another channel to achieve the desired mix. PS. I forgot AGAIN to put your name on the end of the video, sorry!! It's in the description but I clearly need a better process. I think I've solved it now - the credits are next to my logo on my editing master folder, and I use the logo at the end of every video, so I'll see it now. Thanks for bearing with me and my forgetful head!!

How much is it

[@RCTNT]

Click through the link on the Description, that'll give you the current price. They released it for USD$40, and my discount code *may* still work - that's RCTNT Cheers

If anyone reads this after getting this it's an ok remote but the company is trash. They don't know how to put information up on their site. I bought a different set of receivers that don't work with this remote and the company won't take anything back that isn't "defective". So no info provided and you're screwed. Terrible business practices. I'd stay away. I'm posting this message on multiple channels so everyone is warned

[@RCTNT]

They (did) sell the receiver for this radio, I bought one and it's good. I'm guessing you bought the DumboRC receivers. I'll add this note here so others know what you're upset about in particular. I'm sorry you've had a bad run here. For whatever it's worth, the receivers you've got will work with most DumboRC transmitters, so you've at least bought a broadly compatible receiver for future use. The radio receiver you bought says its for their 1/10 on-road cars, which all use a DumboRC radio system; rlaarlo.com/products/6-channel-receiver-including-light-system-control The receiver you needed was available on their site (I bought one myself) , but I've looked for 10 minutes now and can't find it! Has it been removed? I'm not sure. I was going to link it here for anyone else wanting to avoid your situation, but I simply can't find it now. Weird. I wonder whether the hotrc ct8 receiver would work with this radio? I expect it probably would, but I haven't tested this yet. If I do, I'll let you know.

[@fgarcia2277]

@@RCTNT I understand what you're saying but if they put the information on there that should be readily available for them this wouldn't happen. 2nd I went through every bit of information on those pages, which their return policy is" if you're not satisfied with your purchase for ANY reason you can return the item" so.... Yeah. I don't think I'm asking for anything that's unreasonable. You don't have the proper information on your site, I'm within the 30 day return window. I'm not satisfied, all I'm asking for is a return and refund. Can you please tell me why you think that I shouldn't get a refund? Also I'm telling people everywhere so they know how this company acts. It's not all sunshine and rainbows. I also bought 10 of the regular receivers but wanted smaller ones. So I'm a repeat customer.

[@RCTNT]

I'm sorry about this, I think you should have a refund or exchange. I edited my reply before I'd realised you'd replied here, else I'd have continued the discussion instead. 1. It's in 30 days, so yes, fair enough. 2. The receiver you need isn't available now, as far as I can tell - see my edited comment above. 3. You bought 10 of them? Geez yeah I'd be giving you an exchange, though paying return postage would be a point of negotiation possibly. Sorry you're having this experience. That sucks.

[@RCTNT]

I've added a note on the video description to be careful not to buy the DumboRC receivers for this radio. It's not much, but it's something!

[@fgarcia2277]

@@RCTNT thank you, it's something. That way it'll help avoid confusion. If they put that on the description like most other companies do, I would say completely I'm at fault.
