I've always preferred operating elevator trim from a rocker switch on the control stick. This Bearhawk is going to use electric trim.

Many iterations of the trim actuation have been considered, but it long, drawn-out discussions with my BH engineering partner, akschu, we arrived at a completely electric solution that uses only a single linkage: the one where the servo output shaft connections to the trim tam control horn.

Servos used: Bristol SG B6-11T, mainly for its brass output shaft.
