Making the Radiomaster MT12 Even Better!

[@pietronetutube]

Niiiice looking forward to combine this for a long range FPV car with that radio in a next video

[@BadLuckFPV]

14:25 I just died laughing when you started deleting the timers and the remote said stop one last time 😂😂😂😂😂😂

You're the best JB!

[@TheDepep1]

A flysky noble is 300 dollars, has a color touch screen and other nice features. If radiomaster made a 200 dollar MT12 pro with edge tx color screen edition I would buy it in a heart beat.

[@davidfruehwald3353]

You can also disable the steering along with throttle by adding another override for that. Now NOTHING will move until I hit the button. Now I just need to figure out how to take it to the next level and make it so I can't accidentally disarm when throttle is applied.

[@AllevRot]

I have setup SB for that, its location is difficult to accidentally hit in my opinion. I even very much prefer it over the SD that is easily accidentally pressed. Sorry Joshua :)

[@cameronr.massey2578]

Great article. get it all set up but doesn’t work unless you go into sys.and press TBS agent light every time you power up? Isn’t channel 1 usually steering

[@ateaserc]

Keep making these videos on this radio! Great job and easy to understand and it appreciated.

[@TravisGintz]

Thanks for the great videos on this new radio.

[@Mstom178]

This is great, you should make a video on how to bind to a FMS, SCX24, FCX24 and overall how to find out what protocol you have and how to bind the 4in1. I lot of car guys dont know anything about this.

[@JoshuaBardwell]

Unfortunately, most car BnF protocols are not supported by the multiprotocol project. So adding an ELRS receiver may be required.

[@power21100]

@@JoshuaBardwell i just found out from another youtuber. To bind SCX24 v1 receiver units to Radiomaster MT12 with 4-in-1 module choose protocol type "Pelikan" subtype "SCX24".

That's exciting! Is there anybody who is collecting common BnF protocols and how to bind them?

No they are not, I feel it is worth a Vid on it. FMS is blowing up with new items and alot of us buying the MT12 want to know what we can bind to with this radio.both planes and cars @@JoshuaBardwell

[@jamesdash1906]

I just want a radio that doesn't have brown outs !!!!!!! I've got two very expensive pile of parts that were two RC cars. Both did a full throttle rip across the parking lot head-on into a concrete curb

[@CorruptName1]

Most cars use CH1 as Steering and CH2 as Throttle.

[@power21100]

Yeah, but with edge tx you can program it to have channel 16 for steering and channel 8 for throttle, it doesn't really matter its all up to you.

[@fordman3571]

Very helpful videos,do you by chance know how to factory reset this transmitter? Any help would be greatly appreciated. Thanks

[@cedricdelain1856]

Hi Folks ! Great video ! Quick question : is it possible to bind the Radiomaster MT12 (4in1 version) to an esc for CT8A Remote Control. I've received a a RLAARLO Omni Terminator (Carbon Version) but I don't feel confident with the CT8A TX. I tried to bind the MT12 with this esc with the Radiolink protocol (Surface and Dumboc version) with no success. Thank you for your support by advance?

[@blikzems]

Im late to this... i know... the timer is important when practicing rc electric racing... in 1/10 offroad runs are usually between 5 and 7 mins. It is useful to have a timer to stop practice runs at the right time to check temps etc. Over gearing could work out for 6 mins although running hot but might catch fire at 9 mins...

[@jacojojo42]

yea keep making videos about this radio specifically. getting one when off pre-order. would be great

[@JoshuaBardwell]

If you don't preorder, you won't get one any time soon.

[@power21100]

​@@JoshuaBardwelli literally pre ordered it on nov 1st, it took another month to arrive

[@LowetheTechGuy]

I placed my pre-order 2 days after JB's first video of it.

[@zayyandzikraka3833]

Im new to this radio.. how to turn off the fancy led light..?

[@TimBoundy]

3:02 - Timers are used for more than just battery voltage. You might want to practice for a specific amount of time that correlates to the length of a normal race. You might want to check the temperature after a known time to see if gearing needs to change. You might want to use it as a rudimentary lap timing system. You might want to use it in the middle of the race so you know how much time is left in case you need to make a last ditch attempt to pass. You might not even have a battery, some vehicles are powered by fuel.

[@imadabualia4843]

More on this please. Thanks Joshua

[@OGRadGrow]

Awesome explanation of functions 👍🏾

[@NorgeSquad]

Only good reason for timers that I see is when you Race Nitro buggys and the timer let you know when to pit stop

[@LowetheTechGuy]

Also practicing so you can get the optimum mah for racing. Plus stopping at a certain voltage preserves the battery the best.

[@NorgeSquad]

@@LowetheTechGuy yes that too

You’re making me wanna order this Radio for my Kraton 4S. Very informative vid, thank you for sharing.

[@scottoblander9419]

In rock crawling competition, the timer is helpful as you typically have 6 minutes to complete a course before you get a DNF.

[@Sega-and-Mao]

Great tips as always!! Is there any channel delay function on this particular radio Joshua??

[@JoshuaBardwell]

Yes it does have delayed channel function.

@@JoshuaBardwell thanks so much😊 Keep up the good work 👌👌👌and many thanks for all the things I've learned into your channel all those years🙏🙏🙏

[@michaudag]

Very good video, though im having an issue that I can’t quite figure. Trying to use a switch to override a channel just as you show ( physical switch and not a logical one). I can get it working exactly as i want in the special function page, but as soon as i power cycle, the special functions stop working until I scroll through the special function page. When i go to that page and back, then they start working again without any other changes. Any thoughts on what i might be doing wrong? Thanks for the info!

[@Addicted_2RC]

Just came across your channel while looking for info on my Radiomaster MT12 4n1. Awesome job explaining the features and functions of the MT12. I ordered the ranger nano elrs module to have all protocols on one controller. I've never owned a Radiomaster edge tx elrs controller but I'm very excited to learn all about it. I've learned so much watching your videos on repeat while diving into the transmitter settings. I've quickly caught on how to create logical switches and special functions but I can't figure out how to add a cruise control on a dial. Using p1 or p2 as throttle cruise control would be awesome. Any ideas on how this can be done? Awesome videos new subscriber here 👊👊👍👍

[@jaredgreen502]

These videos are very helpful. I am trying to decide if want to pull the trigger on one for sure. It is overkill for trail trucks & rock crawling I do but it also looks like a TX I could use for years. Thank you for sharing

[@99savage1]

it has all the things you could ever grow into at a budget radio price. It's pretty high quality, it can bind to tons of receivers, has extremely long range and has the same if not even more functionality and customizability of a top end radio all while having more channels than most radios under $1k

[@coyoty41]

This radio looks, good but when you bind the FS-BS6 Receiver which has a gyro you can't shut off the svc also when you bind the FS-BS6 Receiver the servo travels to only one direction on steering. also the throttle is ok back and forth is good can you tell me how to fix this problem.

[@jaymitchrc]

On rc surface radio channel 1 is used for steering and channel 2 is used for the esc. Are you able to reassign the channels as the rx seems to be the opposite by default?

[@JoshuaBardwell]

Yes you can assign the channels arbitrarily.

[@davidfruehwald3353]

Yes, you can reconfigure to make it the standard 1 to turn 2 to burn for all models when they are created. Go into Radio Settings, Page 3, Default Channel Order, set to ST from the TS

[@slappomatthew]

go ahead and make more content please. TONS of things that we could dream up to program on this radio. lots of new surface guys have a huge amount to learn about edgetx. basic car things like setting sub-trim, maybe a 3 hour video on how to bind elrs, lol. mechanic adjustments to the radio, programming fun things with the extra button modules etc.

[@blackjungle308]

Awesome on the "arm switch". Everytime I grab a ground RC thing, or even PWM fixed wings, I rant about them not having an "arm switch" to prevent accidental throttling.

[@nickvledder]

Amen!

[@Rckid28]

Only reason I won’t pick this up yet is because it doesn’t have three-way switches near the steering.

Can the timer vibrate? Timer is important for nitro racing or team racing. I have a great video Idea: Visit a local RC track. You will have a great time I am sure.

[@JoshuaBardwell]

The radio has haptic feedback and can be configured to vibration on various conditions.

[@snviper]

@@JoshuaBardwell Thank you!

[@ApappieK]

According the manual the MT12 has Haptic options. All 3 timers have the options: silent, beeps, voice and haptic feedback. Voice feedback is a great thing to play with. With this radio you have more possibilities than you will need or can think of 🙂

If you do another Pro Features can you add a Readout of RxBt whenever you press a Single Press Button. That way we have a Low Battery Warning but also can play Battery Voltage Readout at any time we want to know what the Current Battery Voltage is.

It’s just another special function to play a value whenever a switch is in a certain position.

[@blakeshermer2963]

What would you recommend for your first FPV Lipo charger? The last video about this topic was around 3 years ago and im a little lost.

[@TheEditBro]

I would recommend the isdt q6 it is a good all round charger with decent specs and price. Although it doesn’t have an inbuilt power supply. This means that you would have to buy a power supply separately.

[@Lance1739]

Mr Barwell, I have an idea for some fun content, simulated nitro button, set up a linear throttle to run only to maybe 50% and then a button (NOS Button) overrides and gives 100% throttle, obviously more impressive the more power you have !

[@mrskyrydr]

Josh do you ever dable in LUA stuff? We could surely use a lua for anti lock braking and traction control (opposite to anti lock ) You would need to control length of brake on travel and duration of that traveled length and it needs to have ajustble start points as well as a curve to control its intensity. This works stellar for 2wd stuff to control lockup in corners and such as well as 4wd nitro for cornering to increase your speed entering corners by having steering while braking hard. Great job by the way on your MT12 videos I'll be watching and learning something😊

[@GeezerGramps]

Normally on surface radios ch1 is steering & ch2 is the throttle. This order can be changed in the 1st System menu

[@YRMiniZ]

Any idea about using abs functionality ?

[@dr0n3droid]

Side note: That ESC probably has LVC, making voltage monitoring less important.

[@mootine2007]

Knowing your Voltage is great for determining how much longer you can drive. That way the LVC doesn't just cut out your power when your vehicle is at the other end of the park. FPV pilots like to monitor Voltage at all times. Lol

[@overdosed51]

I have battery voltage and motor Temp telemetry set up in all my rigs. Can't bash without them now

[@davidfruehwald3353]

@@mootine2007 - I wouldn't rely on LVC alone. On my car it discharges to anywhere between 5 % to 10% left which at least from my airplane knowledge is pretty hard on the Lipo.

I set the trim steps to medium or coarse. You can do it in the Model Setup screen.

[@jonnyphenomenon]

I started a GitHub project to build an elrs surface radio last year. I have a couple 1:32 scale rc cars with cameras that have terrible range on the typical radio links. I used a pwm firmware for the rx, and am Arduino for the brains of the radio, along with a elrs jr module. It works great, when it pairs, bit out has trouble pairing and I'm not sure why. Regardless, the moment I got a notice that radio Master was putting out a surface radio I immediately put in a preorder.

[@BigWillieFPV]

I can drive two cars at the same time how do you fix this?

[@JoshuaBardwell]

I'm not sure I understand the outcome that you're asking for? All receiver protocols will control multiple receivers if powered up at the same time. The answer is, don't plug jn 2 different cars at the same time of they are bound to the same controller.

[@BigWillieFPV]

@@JoshuaBardwell yeah understand same as ghost, I thought maybe I hadn’t bound properly, in the setup I choose one car bound to receiver 01 and the other to 02 and thought they’d had some sort of model match, thanks for clearing that up. First time using elrs

[@slaupen]

You could get a crawler liker TRX4 and put switches to control gearbox, lights, differential and a winch

[@JIPPERR_1]

Something like the traxxas trx4 would match this radio really well as it has several accessory features like locking diffs and two speed transmission. Add some lights and fpv it with pan and tilt gimbal. You'll be using a ton of channels mixes etc and be able to take advantage of all that range as well.

[@danjones4002]

How do these custom setup effect different models? Can you customize generic settings for every model, then have model specific settings? Also how do you switch models, i heard you can drive 2 things at the same time. This could be a problem as alot of times at a race you mite finish a race with one car and right after drive a different class, planning on ordering one of these soon!

[@dr0n3droid]

Short answer is yes, you can do anything you've ever thought of doing with a radio. EdgeTx has a fairly steep learning curve, but the possibilities are endless. Press MDL, scroll to the model you want, select it. Only do that though if you have a custom throttle rate/expo that is model specific. A touchy throttle on one car for example. If your models are basically the same throttle/steer, bind them to the same model. If you power them at once, they'll both go. Probably don't do that in the race.

[@slappomatthew]

you can select different models with the model button. most of the settings are per model, although If you want them to be similar you can clone one model and edit it as needed for the next model so your programming is copied over. in the drone world (largely what this software was made for) you do a lot of setup for each model in the flight controller so you can have all your drones bound to one model setup and they are just all always active IE if you powered 2 drones at the same time the Tx would control both. this is less relevant in the surface world as you have different EPA and Trims for each model. but other than that most of the settings would be the same. so setup your first car ( model 1) and then when you goto setup model 2 you can copy it, name it model 2, setup your trims and bind and you are good to go.

[@danjones4002]

Ok so every model is a different bind signal like any other radio im used to. Thanks

With cars you can just run the car until the car stops. Car esc‘s have a cutoff function (I know there are a very very few exceptions but not enough to be relevant). Timers are very very useful when practicing for racing and training for racing. I moved from fpv drones to racing rc cars a while ago (just couldn’t deal with people who yell at you for flying in the middle of nowhere anymore). Seeing you do a review like this was a very welcome sight

[@NUeB_RCFPV]

… but when your into long range FPV driving, you *do* want enough battery to return.

[@slappomatthew]

maybe the max model will be color touch screen? this is afterall their first surface radio and its insanely good value. maybe the next model will be balls to the wall pimped out with color TS and billet everything.

[@RCPhysics]

Great video as usual. Here are a couple of notes from a long-time surface guy who just switched over to the MT12. The Start/Stop timer is really for lap timing for the guys who are racing on a track. It's a pretty useful feature if you are practicing without a race timer system. The one issue is you really should have a way to reset the timer easily, too. That can easily be done by programming one of the other switches as a lap timer reset, but it would have been nice if that could have been set up by default. I've been using battery telemetry on my surface radios for years though FlySky Rx's. I just posted a short showing how I set up my low battery warning using my existing FlySky Rx telemetry. In cars, we usually set up our Low-Voltage cut-off at ~3.2 V/cell since we don't have to worry about our cars/trucks falling out of the sky when our batteries die. I set up my Low voltage warning at ~3.3V/cell to give me enough time to drive back to my "pit" area without worrying about having to do the walk-of-shame to go retrieve my rig.

[@themountain59]

When those radios appeared before Haloween I was intruiged but as more as I watch reviews about it I have to say that I will probably never use one of those. For RC crawling its way to complicated .

[@power21100]

No its not, i literally got this for my furitek cayman pro with 4 wheel steering. I can set it to turn all 4 wheels with one switch that's linked to the steering, or flip another switch to turn it off and just use front steering or flip another switch to manually control the rear steering with the pot. There's no such thing as complicated if you wanna learn and try.
