I have a wheel chair I would like to use the parts to make a remote control mower for my hill. It is a invacare system it has a motor controller and joystick. So I would like to use the existing controller with a wireless controller or buy a motor controller and wireless controller so many can control it. So I need parts and wiring the information.
Thanks
The most common approach is to purchase a new motor controller. Do you know the specs of the motors including nominal voltage, continuous current under load and stall current?
The motors are likely pretty powerful, so a variable speed motor controller will likely be from this category:

Thanks
I have ordered a saber tooth 2x25 controller and a futama remote. This is for the wheel chair motors. I hope this will work together. It seems pretty basic to hook up. I have given up on trying to use the existing controls that the wheel chair came with.
Be careful - many wheelchair motors consume much more than 25A, so there is chance that it may not be powerful enough! If there are specs written on the motors regarding current, it’s important to choose a motor controller which can provide at least that current.
Ok I’ll check the motors out. Thanks for the heads up.
I am hooking up the board and transmitter now. I have a question the receivers have three wires going my to the board for each channel but only one screw. So I am guessing I just us the white wire as the others are to supply power to a servo that I am not useing
There are four screw terminals: GND, V, Ch1 and Ch2.
You connect both of the black wires to the GND terminal, both red wires to V and one signal to Ch1 and the other to Ch2.

Thanks used the wizard to set the dip switches and it’s working now. It’s fast is there anything I can do to make it go half speed?
You’d need to use a programmable RC remote control.
built a RC mower useing the 2x32 controller worked good for two mowing sessions till I blew it up the controller, it had a hard life, now that the trial and error is done time to build it the right way. Using mineral oil helped keep it cool. Not sure how the post pics on here with my phone.
Is there something I can put between the RC reciever and the motor controller to make the controls work more smoothly? I have seen pictures but don’t know what it is.
You can program your joystick to react exponentially to input (if it has that feature).
