W speed transmission for electric cars?

Tech Regular
HPI made one that fit an As. RC10 trans. It worked just fine in a RC10DS. For the most part 2 speeds are not required for electrics. The torque produced by the motors we use as soon as they start turning eliminates the need for a 2 speed. Don

Yokomo has one too which fits the YR4-M2 J Pro. The torque curve of electric motors however eliminates the need for it.

Used to be one on my Kyosho TF2. It was pretty fantastic to use, I still have all of the parts. But there was a 1 way bearing involved which was it's major drawback. It was Extremely delicate, if your car rolled backwards at all (ie a spin, even if it was only for 5-10cm rollback), all the rollers inside the bearing broke, the bearing was set inside a spur gear hub.
My local hobby shop could never get the hub by itself, and it cost $170AU for a new 2speed. I did it twice and then never bothered again
