What is a high thrust line?
A design where the propeller thrust line sits above the center of gravity, the layout most modern gyroplanes use. Adding power pitches the nose down and reducing it pitches the nose up, an effect a properly sized horizontal stabiliser is designed to counter. It is the layout behind the power push over failure mode, engineered around on today's designs, not eliminated outright.
Also called HTL, non-CLT
That is the whole entry for now. The longer version, with the mechanics and worked examples, is still to be written. See autorotation for how those read once they exist.
