RadioMaster MT12 - How To Make It Fast & Latency Test (Beginner's Guide)

Using ELRS with EdgeTX for the first time might be confusing especially from a car transmitter user's perspective.
Also, it baffled me that despite the hype about it being low latency, it's really slow out of the box. Then I found out why.
Hope this video helps newcomers who transition from a surface transmitter to this air transmitter operating system and module.
Also, latency test! Yay!

I'm trying to make as many videos as I can before I go to the dentist and won't be able to record anything for a while.

[@Mossman04]

I’ve been loving your videos! I’ve been trying to find a good brushed motor upgrade for the 284161 so I don’t have to upgrade the esc and then radio. If I do upgrade the radio, I’m going to follow this video. Thanks for these videos!

[@BeaversHobby]

@@Mossman04 Take a look at PN Racing. You will need a motor that has mounting holes at the front. PN seems to be the only one who makes brush motors with mounting holes.

[@rulyiman7597]

is this good enough for drift race? or maybe head to head with sanwaa mt4?

[@BeaversHobby]

@@rulyiman7597 I'd say strictly for racing, Sanwa is better. Personally I think this transmitter is borderline experimental and way too complicated for a racing environment.

[@aquilinefpv2592]

Joushua Bardwell had been a great resource to me for learning Edgetx. Please give a shout out to all the developers who worked on ELRS!

[@wucet1267]

Hello. Thanks for great videos :D I'm planing to buy new radio for rc drifting and rc rock crawling. I'm consider Radiomaster mt12 elrs and Flysky g7p. Which one would You recommend? Is it worth to spend more on mt12 (cost of tx/rx and complicate) to have faster system than g7p? Also do You had throttle runaway issue on mt12?

[@BeaversHobby]

G7P will be more than enough and it already has a good latency with consistency. It also has crawler mixing that is easy to setup. MT12 is only good if you want to tinker with the settings and you are already familiar with the EdgeTX.

[@maxiferrari08]

I would love to see a review and latency test of a sanwa radio like the mt 5

[@BeaversHobby]

I'd like to try it as well but I have no plan to buy another transmitter in the near future. From the spec it should be a few ms faster than this but I don't know if it'll show up on my camera because of that 4ms window for each frame.

[@셰어링youtube]

I bought the 4in1 version and then added the old jumper elrstx I originally used. But it only supports up to f500. Would that be okay?

[@BeaversHobby]

F500 should be fast enough.

[@michalkalavsky]

Thanks for video. I have a question why did you change also non servo channels to 333hz. Is it ok to do it for Hobbywing 1060 brushed ESC? Spec sheet says it has 1kHz PWM frequency. Can this setting damage ESC? Thanks a lot.

[@BeaversHobby]

Hello. I change all the channels to standard digital output frequency to make them a bit faster. If your component has 1kHz then 333Hz will not damage it. Lower frequency than the component is safe to use. In this case you can also set the ESC channel to 1kHz to utilize the full range of data/resolution/speed. Anyway, I keep using 333 just to be safe.

[@ProRCCrawler]

My radio did come with the 1000, however the ER4 receivers still come in at 50. Just changed it to 333hz thanks to your video. I noticed you can go higher, will it hurt the servos?

[@BeaversHobby]

Yes, higher rate will stress and most likely will heat up the servo more. It's recommend to run the same rate as the servo.

[@rickzfpv3118]

Hey Beaver do you know if the MT 12 will bind to a kyosho Mini Z I am doing a lot of mini z racing this year and really like the mt 12 i know it will bind to my Radiolink receivers but would be nice to know if i buy one it will also work with my mini z’s

[@BeaversHobby]

Yes, it will. Choose the 4-in-1 Multiprotocol version and it'll be like the TX16S I did but pistol instead of sticks. Another way if you will also use ELRS is get the ELRS (like I have here) then get a 4-in-1 module. That'll work too.

[@BigWillieFPV]

I am having trouble getting futaba servo CT -701 working on mt12 I have to unplug servo and plug back in to make work, when I restart servo doesn’t work again

[@BeaversHobby]

It's a know issue with the SBUS components on PWM ELRS receivers. Tx/Rx pins will blast out the signal at startup so the component will glitch out. Which pin do you use? I believe the Tx/Rx are on 2 and 3. Try and change the servo to use other pins. Either change the channel or map it to other pin other than 2 and 3. If you use the 3 channel receiver then... oops there's nowhere else to go. I also mentioned this issue in my review. kzbin.info/www/bejne/kKCwhaGmmbSbiassi=LnF6Lg-SQOfFT9x2&t=1011

[@BigWillieFPV]

@@BeaversHobby thanks mate works on channel 4, any down side to using ch4? Thank you, also I was playing around and I removed the esc servo lead from channel 1 and the motor kicked into go for 1/2 a sec lucky I had the pinion disengaged or would have sent car crazy across the bench into my computer, tried it again and same thing, not sure why, esc is Nitride Elcerem, I won’t be doing that while motor is ready but it could happen if I forget later down the track

[@BeaversHobby]

@@BigWillieFPV Don't worry. There's no downside for CH4. Channel 1-4 and 6-9 got full resolution anyway. So you don't have anything on CH1 and only ESC on CH2 then it got initiated with full throttle at startup? That's a bit strange but the signal blast problem might have caused it too. Anyway, using 5 CH receiver is pretty much preferable so we can move anything out of Tx/Rx and have 3 CH receiver in the end. Just assign another channel than CH5/AUX1 to the pin 5 and you'll be OK.

[@BigWillieFPV]

@@BeaversHobby esc was is channel 1 I tried channel 2 and was getting random bursts of throttle, I might move throttle to channel 5 and see if that’s safer

[@BigWillieFPV]

@@BeaversHobbyoh I love your little drift car 🚗 what model is it? Thank you

[@jamesotto8919]

For Mini-z, would you recommend this or the Noble?

[@BeaversHobby]

It depends if you have old FHS (blue antenna) or will just use it with new FHSS (white antenna) and EVO. If you still have the old car then you'll need this MT12. Otherwise Noble is better in every way.

[@jamesotto8919]

@@BeaversHobby it looks like it. I just have a number of receivers. Would be nice to pair them all down

[@BeaversHobby]

@@jamesotto8919 I that case check if your receivers are compatible with 4-in-1. If so MT12 is your one stop option to have everything in 1 transmitter. For a car driver's perspective MT12 is overly complicated but it does a lot of things, way too much for surface vehicles in fact. That's the reason I usually recommend Noble over this. Keep it simple, all the necessary functions are there with easy access.

[@todd92371]

Probably dumb question. Does any of these tips apply to the 4 in 1 version?

[@BeaversHobby]

Unfortunately, no. Only the setup for the car (channel output, etc.) can apply to both versions.

[@LakAyo123]

Wow🎉🎉2024 ของใหม่มาอีกแล้วครับ

[@adamlives]

Mine came set as F1000, got it late January 24.

[@BeaversHobby]

That's really nice! The first time I used it I thought it was so slow. Anyway, do the receiver still come with 50Hz as default setting or they up it to 333 for digital already.

[@adamlives]

@@BeaversHobby Not sure about included er3c-i, didn't take note but my other er5c-i set servo outputs at 50Hz. But creating new models don't set the rate to F1000 either.

[@BeaversHobby]

@@adamlives Thanks for the info.

[@rulyiman7597]

and it have snake game

[@flyboirichh1710]

Bring back the tto1

[@BeaversHobby]

Definitely! This will most likely replace my Futaba 3PK as an outdoor transmitter.
