Servo Tester

This is a device I made to test and setup servos for my RC airplanes. My most recent build was a sailplane with V-tail and spoiler. The servo setup got quite complex. Each ruddervator servo had inputs from both the rudder control and the elevator control. The ruddeer stick required nearly twice the response on the ruddervator as the elevator stick. In addition I wanted dual rates and expo. When the spoiler is activated I needed to mix in some up elevator to offset the loss of lift.
