Russell, Why have the electric motor? Why not a simple knurled wheel to drive your bowden cable, ala Douglas DC3? (if any of you mob are old enough to know that one!) They had a small, adjustable friction wheel in the centre of a fairly large (~ 250mm or 10")trim wheel beside the co-pilot's (?) seat. A modern version for gyros might use a lever control with a smaller lever used to lock the control in position, or even a rachet, to give positive, continuous trim adjustment. Yeah, I know! Electric everything is cool, but also less reliable, more bits to go wrong, etc. Do you know that on the Apollo space module, everything that could possibly be made so was made mechanical rather than electrical or electronic? Even the throttle control for the rocket motor was a cable linkage for reliability and low weight.R.J.W.S.
