One of the ways to slow down a dc motor fast is with an H bridge mosfet
cct. You can have forward, reverse and brake functions. The H bridge
slows down the motor a lot faster than a diode, I tried it on a model
airplane electric motor and the diode made almost no difference at all
in the slow down rate but with the H bridge the motor comes to quick
stop. You could also put in a feed back pot and slow down the pulses
when the cap. gets close to the right position.
