This is drag from air ducted to cooling components.
A motor-driven device for moving control surfaces and throttle of a radio controlled aeroplane.
The removable arm or wheel which bolts to the output shaft of a servo and connects to the pushrod. These are often cut and modified to suit the paricular application. Careful positioning of the holes in the output arms will allow you to produce a mechanical differential effect for airlerons or even throttle control where more precision is required around the idle setting.
This radio feature allows you to install the servos where they can give the best pushrod routing without concern about the direction of servo rotation. When your installation is complete, turn on your radio and check each channel. If a channel operates opposite of its intended direction, a simple flick of a switch corrects the problem.
A device used to reduce noise from the exhaust side of an engine.
This is drag due to the surface texture and area.
