12degrees collictive pitch

[slyflyer1]

My motor is tuned but when I give a hard collictive seems like lm loosing head speed
do l have too much collictive at 12degrees or is my head speed too low ? I don't have
A tax. So im guessing in normal 1700 to 1800+ in idle1 2000 to 2150 ln idle2 2250 to
2350.

Headspeed too low... You want to be at 2500 - 2700.
