Hey Lee, I'm always fair. I'm picturing an S10 with a 11" motor. Your
foot in it, shift it a couple times and get out and sweep up the
pieces of u-joint on the ground.
If you have a big enough motor (and controller and batteries), you can
easily produce far more torque than the stock drive train can handle. No
doubt about it! But this has nothing to do with your reversing setup.
I was just observing that you don't want to make it *too* hard to go
from forward to reverse quickly, because there are times you may need to
do it.
Most EV controllers are in fact derived from industrial EV controllers
for fork lifts etc. They already have an adjustable ramp-up time, so
they won't go from 0 to full current instantly. They also have
adjustable current limits, which limit motor torque. Some even have
interlocks to limit current in case of rapid forward/reverse
transitions. These features are there so you *won't* break things by
careless operation.
Obviously, you can set up your controller to defeat these limiters. Then
you are free to go very fast and/or break the vehicle, as you choose.
