I already have the spinner cone and its already cut for a three blades. My DLE 30 turns the same prop 7,250 rpm and a 32 RCGF 7,150 rpm. So at 7,320 rpm and maybe picking up another 100 rpm when broken in, the NGH 35 is close to what I was expecting. Anyway, just holding the airplane at full throttle, it seems to have plenty of thrust and will be more than enough power. Worried about the 1.2 lbs increase in weight, not lack of power. The cg is exactly where it was before so it should fly ok.
