I try it this week.
I change the gear ratio to 1:8.5, engine and colling fan.
The result is I think I create a monster
She fly at any rpm and any extreme pitch with no bog at all. The trust both on normal fly or inverted fly is tremendous.
Guys, the only things I regret is I don't try this earlier
The fly time is slightly down, but I don't care.
I fly with confidence, know that she will react on my command without bog al all
