I recall a mention of the electrical motor running while clutches changed the drive from one authority to another. Is the stopping of the wheel reliant on a clutch slipping? It seems from this thread that the smaller diameter wheel might be a bit of a challenge.
I asked before, but does anyone know how long the motor runs on for? I find it hard to believe it is powered down after every single pulse of the thumb switches, so I assume a lag in the power-down.
