RC Master Class 8: Trimming, Washout, and Angle-of-Incidence Tuning

High-performance RC aircraft rarely fly perfectly out of the box. Even the best designs require trimming (a combination of transmitter programming, airframe adjustments, and test-flight techniques) to achieve neutral, predictable handling. When properly tuned, a trimmed aircraft tracks straight, holds knife-edge lines effortlessly, and recovers from stalls cleanly. This master class covers washout application, angle-of-incidence tuning, and precision trimming methods used by competitive aerobatic pilots. 1. The Goal of Proper Trimming A well-trimmed airplane should:...
