June 13, 2025Application(s): F5J : Introduction (Holien) Electric Powered Sailplane Elevator, Rudder, Flaperons.
Comments: I’ve bought 9 Frsky Hv5612 servos for 2 Introduction Electric powered sailplanes, 1 spair.
After 3 Years I needed to use the spair, as the Elevator in my main tootsie had a dirty potetiometer; varied the center 10% or so.
It was still useable, but too teadious for me.
I like these, not super acurate, but strong and reliable.
