The motor shaft is about 1 inch dia. I'd say it's not a potential weak point.

The forklift controller has an "acceleration ramp" built in, and I believe it's also adjustable via a pot. On the plus side (?) We're running relatively low voltage from a small pack, so we're not going to be putting out prodigous amps (relative to the Tesla roadster, for example).

I thought the soft coupler was pretty clever too, until I talked to a commercial EV builder last week. He suggested we were going to wear out/chew up that urethane spacer in short order, and actually said a fixed connection between the motor & input shaft would have been fine. Hmm! There are all kinds of ways to do this.

Hopefully this evening I'll get a few more bits 'n' pieces out of the car in preparation for the motor-ectomy.
