Fantastic tutorial, Lee! Thanks a bunch! 😃 March 28th I'm going to buy the rc truck I mentioned in a comment the other day. Then I'm going to need to get a new brushless esc for it (it's 2 in one with the receiver, unfortunately) and, then, I'm going to get the MT12 and 2 receivers. 😊 The car I already have has a brushed motor and I already have a 60A esc, which going to be overkill for it, but hey... I already have it. 😊 Anyway, stay safe there with your family! 🖖😊
Hi Lee, Great video and information about the Radiomaster MT12, actually I just purchased it. Thanks again for the video and looking forward to seeing more videos on the MT12 and your truck
I very happy I found your video. Thanks u for making this. I'm not good at English so I will need time to understand it. But I allready see how good u designed the whole video. Looks very nice and clear for me.
Have to say you’re a mind reader. I saw this transmitter the other day and wondered how it all worked. I race rc cars, pan cars, touring cars and buggies. You’re spot on with the steering expo. Nearly everyone runs -35 for steering. Some people also run -10 on throttle just to keep the car smooth out the corners. To set the steering on a car without buying a setup station. Get some hard plastic or some setup wheels. Put car on plain paper. Measure the width of the setup wheels so for example 100mm from wheel to wheel. You’ll need a ruler for this part. Draw two lines 100mm apart and place the car so the wheels are aligned with the lines. Turn the wheel left, then mark the outer angle with a ruler. Do same for right hand side. Then measure the distances. Make the left and right the same. That will stabilise the steering. You can also measure your steering angle this way. You can do this in the end points save messing with steering turnbuckles. If after you’ve put a new receiver in and your steering isn’t straight. You can use the sub trim under steering to level out the wheels to true. You don’t have to mess with turnbuckles that way. Most people don’t run 100% steering rate with a wheel. So back it down to 90-95% that will take a lot of the slap out the steering when you let go of the wheel. If the radio has channel timing you can add or subtract 0.01s to the channel if the steering is way to snappy as well. Will make it feel smoother.
Matek do a PWM ELRS receiver (the vario one) that has a second UART to accept a GPS, which is cool for speed running or just having a live speedo (and telemetry luas!)
Excellent video. Been working on my truck properly talking to my tx16s. Had the fwd/rev and sterring working good from the start. Only thing thats stumping me is the LED light on front of the truck. Have it on ch. 3, and elrs receiver channel setup for on/off mode but the radio only dims the LED halfway. Had it working b4 then it started just dimming again. Any tips?
Make sure the channel controlling the lights goes full travel (-100 to +100), it sounds like it's only going to middle channel value one way. Use the channel monitor to check... Happy flying
does anyone know can someone explain how do i make rc car with FORWARD AND REVERSE? i got only quad components... esc, brushless motor.. ive constructed with hotglue makeshift rc car but it only goes forward. i have radiomaster pocket elrs...i would expect it to be able to behave similiar to yours pistol controller just not with trigger but with stick which is self centering. my english isnt best but i hope you understand... how do i tell it to go forward or back? do i need any special components for it? drones are able to spin motors in both directions usually so i dont understand
Besides still looking for a way to move my pan servo *more* than 90 ° there's one more thing on my mind: brake/reverse light; so whenever throttle is less than -10 brake-light shall go on. How can I do this? I also get wrong voltage readings / warnings, once the voltage drops below warning treshold, even after changing the car's battery; this is quite annoying.
@@Painless360 No idea, how I could do that. But when mounting the camera to that car I just noticed, that I can not use much more than 90° anyway - it needs a protecting frame around the camera which blocks sight to the sides. LOL :-D

Best of luck, I am told that my accent isn't too hard to follow from non English speakers!
@Painless360 your accent is great. Nice, clear und easy to understand. I do just don't know much English words.
Just what I was looking for Lee. Thank you
Hi Lee, Great video and information about the MT12. Well as you know, I purchased the MT12 4N1 version, but switch to the ELRS Version
oh?
may i know why u do that?
Waiting for my new rlaarlo omni terminator and looking to add the radiomaster for sure 👍
Great intro!
Can you point me in the right direction for adding speed or rpm telemetry from a vehicle to the MT12 (ELRS)?
I'm not sure. A gps sensor would be needed... best of luck

Stay tuned some cool tricks with steering rates coming in a video soon...

@Painless360 thanks. Will check it out.
Love it ... whats next .. add a FC and ardurover in it as well :P
Maybe!! 😁
Thank you, kind sir!
so i have internal receiver from WLToys 104009
is there anyway put an ELRS without change the ESC ?
Weill radiomaster Mt12 a ELRS work with Mini Z FHSS protocol?? With super low latency ?
Just subd fpr this video. Thanks.
Awsome! But question. Can you do Avarage cell battery volt? Im bad at math lol
Doesn't look obvious - github.com/EdgeTX/edgetx/issues/3030

Car ESCs are designed to provide forward and reverse... see my car videos...
