RE: Hitec Servos & Futaba Receiver?
Strange that people haven`t heard of the HS-81 servoes... They are in fact been very popular in sailplanes together with the HS-85. Nylon-gear on ailerons and metal-gear on flaps. Have some dozens myself, and me and a lot of others have good experience with those in sailplanes, but not that good experience in motorplanes. Their potmeters don`t like vibration, like a lot of other cheap Hitecs. Put it on the throttle and they die fast.
