John:

I am positively a beginner in this hobby for about two and a half years, now. From all I could determine, the model should fly level at half throttle. The Guardian requires zeroing out the transmitter trim adjustments and ensuring the transmitter throws are at 100% (I interpret transmitter throws as end point adjustments.) I, like you, mechanically set all the control surfaces even with whatever they are attached to. The Guardian maintains proper yaw and roll even with poorly adjusted surfaces. But--a couple of my planes want to climb at half throttle so the Guardian is obviously in need of pitch adjustment. That adjustment requires that I have the plane in its "level configuration" before telling the computer to adjust and record everything (I use a small laptop running Windows XP to program the Guardian.) I've tried compensating after flying, but that is becoming a pain. I need a general way of determining the pitch (while it is at the bench) of a plane that will fly level at half throttle with no transmitter trim. Is it a line from the center of the propeller to the elevator, or the elevator is level, or the bottom of the wing (if it's flat) is level, or what? Or am I stuck with guessing? I am reluctant to but in on some forum and ask my questions. I don't want some "expert" to give me a ration of crapolla. But if that"s my only resort, I would gratefully appreciate any advice/suggestions.
