hi guys, thanks for the advice, the 4 motors, 2 controllers and the 1 joystick came from 2 identical wheelchairs they are quite old controllers and joystick, they are penny + giles d49464/5 controllers, what i had planed to is use both controller, with both the wiring looms from the chairs and wire the looms into 1 joystick, speed control but i wasnt sure if this would work? or if the 2 controllers would be to much for the 1 joystick, speed control, im not that cleaver when it come to electronics as i am new to all this kind of stuff???
