3 channels, 4 functions. How do I cheat my radio?

[arthurc10]

Is there anyway to cheat or mod a 3 channel radio to control 4 functions?

Fundamental throttle and front steer, but then I want to run rear steer and shifting the trans.

No, I know I can mix front and rear steer on the same channel and switch the polarity to do normal steer, but what if I want to crab or do rear only?

I have not purchased a radio, but I can promise I cant afford a 3pmx or a 4pk, so suggestions are welcome.

It would help if we knew what sort of radio you have.

I am very fond of the MX3, but I dont know what mods have been proven on one for this kinda thing. Two speed trans, so a 2 position switch for shifting would be perfect, and a 3 position would work for the steering. Doesnt necessarily have to be a pot for the rear steer. I wont complain if it is, but its not needed.

Tmk there is no 3ch radio that can control 4 channels like you want. Radios with steering mixing still use all 3 channels. You need a true 4ch radio. Since you are on a budget, go to overkillrc and get one of their hacked flysky gt3b's or new gt3c's which can have 3 to 8 channels from a pistol grip controller for under 100$ the one who owns and runs overkillrc is losikid (a vendor on here) and he provides great support for it

I have a 4ch airplane radio. Should I use it, or buy a GT3? I have read lots about them, and like the functions and price. The thing looks kinda funky, but if it works, it works.

I just messed around with that 4 channel stick radio. I can shift/ rear steer with the left stick, and throttle/ front steer with the right stick. It will work, just takes some getting used to. I dont comp, so I think the radio will be "fine." Should I just be cautious and make sure no one is flying? Which rarely ever happens anyway, but still.

I dont know if a plane radio on the surface is taboo or not.

Just to be clear, its a gt3B or a gt3C that is hackable, not a gt3.

It's illegal to use a 72 mHz radio for surface operation.

That may be true but who is going to enforce it if you are bashing your rig in your back yard. And a lot of the guys who are into the 1/14 semis and construction equipment use air radios for the number of channels including myself till I got the hacked gt3b

I dont think any planes are out where I crawl, and if they are, what is the likelihood they still use 72 and mot 2.4?

But I did some Google on it, and found lots of threads stating how bad of an idea it can be, and how no matter what, accidents can happen with interference.

So I can have it retuned, or buy a different radio altogether.

Or just say fug it and use it? lol

Damn crawler. What to do, what to do. I can afford a quality radio, but not $250 radio lol.

^ get one of those and you will be able to what ever you like for a reasonable price.

+1, unbeatable quality / price of the GT3B/C
