Hi beaver. So this one because fhss can also bind with mini z ?

[@BeaversHobby]

@@OswaldBeef Unfortunately, no. FHSS is just the name of a method for skipping frequency to avoid interference. Most radio nowadays use this method, hence pretty much every radio got the "FHSS" written on it. A radio talks to a receiver via protocol which dictates the way to skip (hop) between frequency and possibly other attributes like transmitting encryption and telemetry. And each brand has its own protocol.

[@OswaldBeef]

@@BeaversHobby oh I thought fhss was the name of protocol oops. What protocol is it? I have used afhs and afhs 2a

[@BeaversHobby]

@@OswaldBeef It's Radiolink own protocol and they don't have the name yet so we just call it Radiolink protocol. The AFHDS is Flysky's protocol.

Hey I got that remote on amazon a month ago. Also if you remember my mini Q rc car I finally burned out the ESC by using some amazon rechargeable battery’s and so I swapped the parts and used this transmitter and radio and it runs really great. For the price on amazon I really like this radio

Which batteries were you using?

[@howardcrews9196]

I'm new rc hobby so I buy that Radio link rc4gt. I'm having little trouble setting up . I working on it. I like video on the unboxing.

[@BeaversHobby]

Take it slow. Try and study the manual to see what you want to do. If there's anything you don't understand, feel free to ask. Some setups you need to know: - REV or channel reversing, this will reverse the control so for example if your car turns in the opposite direction, you need to reverse channel 1. - EPA or end point, this limits the end of each side of the channel so you can limit the left and right turn separately and make the car turns equally to both sides.

Nice vid. One question, i hace the same radio, but Is a V3 ed. I have a problem for insert the lipo PIN of my battery on the recev. So, please, where Is the correct channel for insert this... The First 2ch. are used for steering and second for Throttle.. Thx for your work

[@BeaversHobby]

You can power the receiver from any channel. Power and ground are all connected across all channels. If channel 1 and 2 are occupied then you can use channel 3 or the last channel on your receiver so it's easier to plug and unplug. **Important!** Don't forget to remove the power cable (red wire) from the ESC if you plug the battery to the receiver directly. Also check if the voltage is applicable. If I remember correctly the receiver takes up to 10V so 2S or even 2S HV will be fine.

[@SlickDiecast]

Thank you for showing this! It helped me a lot.

[@putimir]

Hi, can you please explain how to setup dual rates, so I can switch the rates with, let's say switch D (SWD)? Thanks a lot!

[@BeaversHobby]

Unfortunately this transmitter can't assign function to button, only mixing so you can't assign D/R to any button and have to go into the menu to set it.

[@putimir]

@@BeaversHobby Thanks a lot, thats why I was struggling so much :) Too bad though...the SWD button seems ideal for such a function.

[@BeaversHobby]

@@putimir You'll need a mid-range radio at least to have the button assignment function. Right now I'm using Flysky Noble NB4 which can map pretty much anything including D/R to any dial or button on the radio.

As always, great and very informative review. Have you ever compare this radio with sanwa mx-6 in terms of responsiveness and speed ? Which one will you use ? I'm on a tight budget and in between choosing these radio 😁

[@BeaversHobby]

Sorry I didn't buy the MX-6 because the additional receiver is very expensive and it won't be a budget radio anymore if you have more than 1 car. Check receiver price too when you are looking at a transmitter.

[@adhienoor]

Copy that beaver, will do....thanks 👍

[@mbazani]

Thanks for the good review! How would you compare it with the flysky fs-gt5? In terms of latency/speed. Would it be superior? Thanks in advance!

[@BeaversHobby]

It's about the same in terms of latency between Radiolink vs AFHDS 2A. As far as I can tell Radiolink has better consistency within the delay. As for the range, Radiolink has better range. GT5 has the advantage at crawler mixing.

[@Weaselpro]

I still wondering, why did they not hide an antena inside and make this upper hole for fixing the camera or smartphone. Its so logic.

[@BeaversHobby]

I guess making the internal antenna is trickier than just carrying over the previous design. Personally I'd like them to make a flip antenna like Flysky GT5. That'd make this radio much more easier to carry.

[@Weaselpro]

@@BeaversHobby The antena itself in RL is 4 sm long wire and its nothing to do to make it flip or outside. It fits everywhere inside the body. I did it by myself easily.

[@ronnyventura1711]

One question I have. one of these is being deprogrammed from the factory. how can I put it in functional again, please?

[@BeaversHobby]

Deprogrammed? Does it turn on? When you move the trigger and wheel, does it show on the screen? If so and it doesn't connect to the receiver then you only need to bind it to the receiver. Turn the car (and receiver) on then hold the small button on the side, it'll blink. Then turn the transmitter on.

can you tell me the brand and model of the servo, motor, esc and battery

[@BeaversHobby]

The ones you see in the video are old stuffs that got replaced with never versions. So I'll tell you what are available now. - Servo: AFRC D1802MG - Motor: Surpass Rocket 1410 V2 - ESC: DasMikro V3 or PN Racing V2 - Battery: This is a stock WLtoys K989/284131 battery but if you are looking for an upgrade, check out GNB 2S 350mAh or 450mAh if you need a bigger one.

Not directly. You will have to use multiprotocol module hooking up to the Radiolink and set the module to Mini-Z FHSS. Here's the tutorial for hooking up the module. kzbin.info/www/bejne/sHvQmJKdq5hnq9U And here's the Mini-Z with multiprotocol. kzbin.info/www/bejne/iIacl3uprZKImcU

For onboard gyro use channel 3 (VR dial) to adjust the gyro gain. If you use an external gyro, turn the gyro on the receiver off first then use channel 3 to control it.

[@ReezLah.]

@@BeaversHobby you mean for the external gyro place it in channel 3 also to control it from VR?

@@ReezLah. Yes, exactly. You can use channel 3 as a regular VR channel by turning off the onboard gyro.

[@chadranney]

I recently built a GLD with this as my radio. Works wonderfully. I am having a hard time with one thing however. I can’t seem to get my gyro (not the built in one) to function through the transmitter. It works when I manually change the gain, but it would be nice to get it set up on the remote. Are there any other settings you would recommend tweaking on the transmitter to make the GLD perform better? Thanks!

[@BeaversHobby]

Make sure the onboard gyro is off (green light) then set channel 3 to VR and plug the 1 wire plug from gyro to channel 3 and you should be able to adjust it on the transmitter. However, make sure you don't touch the dial accidentally.

[@chadranney]

@@BeaversHobby one more question: what upgrade parts provide the greatest increase in performance?

[@BeaversHobby]

@@chadranney Front aluminium bulkhead. It doesn't have steering stopper (not that you need one in the first place) so the steering angle improves a bit and it also lower the front shock down so you don't have to pad the shock with as many clips. You'll have to get front aluminium shock tower as well because some holes on standard plastic shock tower won't fit the upgrade bulkhead. Another essential upgrade is caster adjustable plate. So, to me these 3 improve the car a lot and definitely worth the price. - Front aluminium bulkhead - Front shock tower (needed to use with new bulkhead) - Adjustable front caster mount

[@danielkingo1602]

Which is better this or GT3C?

[@BeaversHobby]

Definitely this. Get the current version which is V3. GT3C is really old now, the signal is not that strong or consistent. Build quality also much worse compared to RC4GS.

[@maxmayev]

Hellow. How do you think, is it possible to connect fpv transmitter and camera directly to the receiver? What current can the receiver produce? There are a 5 volt 500 milliamp fpv transmitters,will they have enough power, won't the receiver burn out

[@BeaversHobby]

The receiver gets the power from the BEC on the ESC so whatever the ESC outputs, that's what the receiver gets. Mostly the BEC is 5V so you can plug the camera + receiver into the receiver no problem at all. I do it all the time with Runcam Nano 2 + Eachine DTX03 TX DVR.

I'm get the hgp408 hummer. Can i use one of the buttons or switch to change the transmission settings from high to low?

[@BeaversHobby]

I suppose the transmission is controlled by a servo and it has 2 speed. If so, yes, you can. You'll need to set it to toggle switch then set end point on that channel (3 or 4) so the servo that controls transmission knows where to move from one end to the other.

It depends on your budget. Best under $300 = Noble NB4 Best under $150 = RC4GS If you want the best response time, best resolution from the beginning, get the Noble NB4.

[@BeaversHobby]

@@efaracing4000 Again, it depends if it's drift car or touring (grip) car setup and track length. For drifting 2500KV is for small track under 2x2m, 3500KV is a universal standard and it's easy to gear up or gear down, for a large track like 5x5 and over I recommend 5500KV. As for touring you'd start at around 3500KV, it's easy to drive because it'll give out the power around a standard brushed motor. 5500KV is faster and versatile, 7500KV if you have long straight. Don't worry about using sensored motor with sensorless ESC. It'll work just like a sensorless motor. I used Swave ZM2 motor with GL Racing ESC while saving up for a sensored ESC too.

I am having issues running multiple MRC cars at the same time they seem to be picking up Radio interference. Do you think it might work for me to switch to this radio with included esc to fix the problem?

You can try re-bind the car first if it has a button on the 2-in-1 unit. Yes, you can replace the radio to fix the problem. However this radio (or actually this radio in the market) doesn't come with an ESC, just a receiver so you'll have to get an ESC too.

​@@R-EVLMNKY Ball differential is a differential that can adjust the tension. It's more suitable for touring because you'll need to adjust how the car get the power down. For AWD drifting you'll need locked diff at the back and front one way at the front. For RWD drifting ball diff adjust it to open will allow easier slide control but will initiate a slide a bit harder. Tighter diff will get the power down easier and initiate a slide easier.
