engine.
‡ Control Surface
Any one of the various moveable portions of the wings, tail surfaces, or canard.
‡ Conventional Gear
The landing gear arrangement where the airplane has a main gear and a tailwheel.
‡ Coreless motor
In a conventional servo, the motor has a steel core armature wrapped in wire that spins inside the magnets.
In a coreless design, the armature uses a thin wire mesh that forms a cup that spins around the outside of the
magnet eliminating the heavy steel core. A coreless motor does not have magnets as standard servo motors
do, so they have a smoother, more constant, and stronger action. Regular servo motors have either 3 or 5
magnets (poles) which when the armature is between these, the servo motor is at its weakest.
