I have tried looking for a thread for someone doing this but can't find one. If you can point me in the right direction, please help! :)

Looking to use two eBike /Scooter hub motors to drive a small 4wheel vehicle by remote control (radio operated).
I am looking to use something like this

to control two cheap Chinese controllers with reverse capability.

Something like this

Does anyone know if the outputs of this type of RC controller can control the 2 bldc motors to create a "skidsteer" style vehicle?

If you were doing something like this, how would you do it? I am not married to any of the above components and just looking to get the result!

Thanks so much!

actually I guess I would need a controller with reverse capability! Perhaps the attached?

First, that RC transmitter outputs a RC PWM signal while those motor controllers need 0-5V analog signals. You could use something like the product below to convert the signals, but even still, I'm not sure those controllers will reverse the way you want them to.

You could also use motor controllers that accept RC PWM signals like VESC's or brushless RC car ESC's.

Second, that RC transmitter doesn't look like it has programmable mixing where it can output the signals for tank steering. You'll need a nicer transmitter or a V-tail mixer such as the one linked below.

I would probably go with VESC's myself and a nicer transmitter that can do the mixing itself.
