Hello!
I would like some help on electric motor speed increase from manufacturer spec.
I just replaced left motor as last one failed. The replacement
motor is slower than the original. On the radio i use left stick for left track,
forwards and reverse. Same for right stick - forward and reverse for right track.
I can get the mower to run straight at slightly reduced speed, probably fine for
mowing. So the replacement motor was made slightly differently to it's original.
800watts, 24volts. I guess this happens occasionally! Is there a way to increase
voltage via the speed controller, nothing is obvious on the unit. The two black
units with small fans. Could I replace this one with a Sabertooth Regenerative
Motor Driver or Smartdrive Driver. Can you adjust one channel for longer
travel. Is there another way where the replacement motor speed is increased
where both radio/transmitter sticks are maximum travelling at same speed.
Any help would be great! Current Radio: Microzone MC6C.
Thanks a lot
