Normal curve adjustment
*Normal curve creates a basic curve centered around
hovering. Use it along with the normal pitch curve and
adjust so that up/down control results in a constant engine
speed.
Idle up curve adjustment
*Set a idle up curve that maintains a constant speed at all
times, even during operation which reduces the pitch
performed in flight. Create a curve matched to loop, roll,
3D, or other purposes and the idle up curve according to
the performance.
Operation precautions
Warning
When starting the engine and flying, always
set the idle up condition switch to OFF and
start the engine at idle.
