Just wondered if anyone else uses these electric motors and if you do, have you sucessfully linked an electronic engine sound module to them?
if you have,............. how?

I cant get a sound module to pick up the volt change from a robbe motor, to enable the "rev's" to climb.
I can get normal engine tickover noise, but if you raise the throttle, the revs [noise] dont pickup, but motors increase speed fine, no problem.

I have tried both a roobe large engine sound module and a caldercraft unit, both to no avail.

Please, any info would be appreciated,
