An Easy, Inexpensive Way to Maximize Flight Performance.
Avoid control problems in the air — check control throws on the ground with the AccuThrow Control Surface Deflection Meter from Great Planes. Once it’s attached, simply align the “0” mark on the ruler with the edge of the control surface. Deflect it from your radio, and you'll know in seconds if it's in “spec” or in need of adjustment. Great for setting up dual rates, too.
