Tech Notes


Be aware that high vibration gas (not glow) engines combined with large control surfaces and large throws (3D models) can put undue strain on the gears. Metal geared servos are recommended for these applications even if under 12lbs.


Do not use thread lockers on Karbonite geared servo as it will cause the output shaft to fail.
