R/C Cars and Open/EdgeTX: Adjusting the sensitivity of the steering automatically

[@robertrupp9247]

PAINLESS 360:) Thank you so much for your response - I will place in affect immediately!!!!

[@vince086]

Would be nice if there was a "pistol style" TX that could run Open/EdgeTX. Bonus points if it can take a module.

[@RollnHeavyKevy]

I totally agree with this. I even emailed jumper about this. Never heard back. 😕. I've thought about building my own out of one of the game style controllers like the zorro.

[@vince086]

@@RollnHeavyKevy Try Radiomaster, they seem to be more on the ball. Thought about it as well. There's a fair bit of work involved. Would need the cheapest OpenTX radio and a donner pistol grip radio.

[@RollnHeavyKevy]

@@vince086 yes radio master was next on my list.

[@MartinHapl]

Exactly!

[@heady2008]

I would imagine that by now you are aware of the new RadioMaster MT12?

[@MCsCreations]

Fantastic, Lee! Thanks a lot! 😃 This can be really helpful!!! Stay safe there with your family! 🖖😊

[@robertrupp9247]

I had to chime back in I AM THRILLED WITH THIS SIR!!

[@stevo43068]

The *TX, is awesome, the control one has over so many variables.

Excellent video Lee, For the last couple of years I have been trying to figure out how to do a 4 wheel steering on a Rock crawler that I could switch from crab crawl to separate steering or turn it off. I definitely need to look at this and do some reading. Thanks again for the video and information about a F.C in a rc car.

[@Painless360]

I have a video on that I think.. check out the cars playlist... if it isn't what you want then let me know... best of luck

Let's say you're using CH4 for your front steering and CH5 for your rear steering. Firstly duplicate the CH4 mixer for CH5: ADD Aileron (Weight 100, Offset 0) Then let's say you want to use SC to toggle the direction of the rear steering - Add the following line to the CH5 mixer: MUL MAX (Weight -100, Offset 0, Switch SC) This will invert (Multiply by -100%) CH5 if SC is enabled. You can also make this variable using S1 - Instead of the SC line, add the following to the CH5 mixer instead: MUL S1 (Weight -100, Offset 0) This will mean that when S1 is set to 0%, CH5 will follow CH4 - But when S1 is set to 100%, CH5 will be inverted. (And anything in-between) You can also add the SC switch from before to this line to allow it to be toggled on and off.

I'm a drone guy but decided to add RC Cars on my hobby list. Learning so much from you. This vid on steering sensitivity is priceless. I actually don't like the RC Car wheel & trigger remotes. Following your advice I've set up my Radiomaster Boxer to use my roll stick for steering & my throttle stick for throttle with a switch for reverse (resolution is a great benefit). Is there a way to get the car to break without have to throw the switch? As in going to zero throttle and break like the trigger control. Thanks for all you do.

[@NATGEOANDSTUFFPaulbrannan]

Awesome Lee sorry not been commenting my friend I been real busy .doing alot of school talks lately and on a house build.hope your well

[@jwc4520]

Interesting, while I dont do autos it still has perhaps some use on canards? However have you done a sail boat? Got one a few years ago, haven't a clue , makes a great dust collector as I could not figure the winch out ...lol take care .

[@Painless360]

Are you a Patreon? Happy to help you figure it out...

[@GeezerGramps]

I like open tx I just wish there was a pistol grip radio that ran it.

[@rogueFactor]

i wonder if i can do this with just the GUI on the Flysky Noble Pro.🧐

[@jamesceastep8874]

Lee: This is perfect for an oversteer problem I have with several of my brushed monster cars (quite fast). Do you have any tips that would allow driving these vehicles using my multimodule hobby grade transmitters? Thanks! - Jim

[@Painless360]

You need something programmable to do stuff like this if it isnt a built in function...

[@crazicat]

The multimodule devs have been adding the ability to bind to several surface receivers. I can now bind my TX16s to the Axial crawlers.

[@jaredsayrc4947]

I wish you use spektrum Pistol grip remote

[@Painless360]

I don't have one here. Most have very basic features too.. Happy driving!

[@TheWebstaff]

Now you have that sorted time to get a car and pop some fpv on it?.. 🙂

[@Painless360]

Already done that on the channel, check out the car videos.... happy flying!

[@yngndrw.]

A slightly different method, with linear control via one of the knobs on the radio: (Uses a dummy channel to calculate the amount of adjustment) Mixer for CH32 (The dummy channel): ADD Throttle (Weight 50, Offset 50) MUL S1 (Weight 50, Offset 50) [The knob] Mixer for CH4 (The steering channel): ADD Aileron (Weight 100, Offset 0) [The normal input] MUL CH32 (Weight -100, Offset 100) [The adjustment] I did try to use telemetry to drive the adjustment by assigning a telemetry sensor to an input and using that in-place of S1, but I couldn't get the telemetry simulator to work - The idea for this being that you could use the current speed of the vehicle if you had the appropriate sensors.

[@giuseppe.marino]

Hi, I would like to do something like that. I want to gradually reduce the sensitivity of the steering servo by using one of the knobs on my taranis q x7. I have only two channels: channel 3 for throttle servo Channel 4 for steering servo. How can I do that?

[@yngndrw.]

@@giuseppe.marino You just need to latter part of what I said, add a new line to your channel 4 mixer: Source: S1 (The knob you want to use) Weight: -100 (Counterclockwise will increase sensitivity by up to 100%, middle will be normal, clockwise will decrease sensitivity by up to 100% - You can change the weight to say -50 to get a -50% to +50% range instead or you could remove the minus to invert it) Offset: 100 Make sure you set it to multiply and not add
