I had 4 flights today with apc 22x10e which is much much quieter that 22x10 pro zinger as it should. I believe I have achieved my goal on proper cooling on both ESC and the motor.

Temp measurement after 10min flight shows 88deg with 72deg ambient temp. While ESC recorded 99deg. The motor actually felt cold to the touch.
4 flights with non modified CF gear with no problems.

This plane, although tracks better and flies lighter than my PW extra, has some snapping tendensies which makes me a little nervous. Hope to get more acquainted with its habits during next few flights.


The final intake opening has a concentric cylinder with gap of 3/8inch causing all incoming air to directly affect the motor temp.
