RE: Servo Buzzing
I appreciate the answers; let me clarify; The Plane is a P-47, the retracts are Robarts Pnuematic, and the servo controlling the valve is alright never binds, no buzzing, the gear door is mechanical, servo articulated; does not buzz on the ground when doors are open , gear down; its when the gear is retracted and the door is closed the servo buzzes and probably still buzzes while in flight. If I adjust the EPA, trim or the linkage to stop the buzzing, the gear door does not close completely; allowing the winsdtream to enter the gear compartment; if the flights were about 15 mins, do you think the drain on the 1600 Mah battery from the servo buzzing be significant, I thought of putting some thin foam tape around the door edges to seal off the door so I wouildn't have to close the door as tight to possible stop the buzzing; or to solve the problem completly, use small air cylinders and another servo/valve to open/close the gear door. What do others use to operate gear doors?
