Hi

I have the WM clipped cub also and a buddy has one. Mine is powered with a magnum .52, and his is a TT pro .46. Mine has plenty of power for the cub and scale speed at 1/3 to 1/2 throttle. His will how do I say this a HOVERING CUB? Well either engine will work but the .40 would be plenty of power.
I fly off matting so don't know about grass. I guess that's why I never had the nose over problem. I also ease into the takeoff roll to maintain tracking down the runway and have no problem. Others feel it is a groundlooping squirrel and just nail and take off ASAP. Again either way gets you in the air but I think the classic style looks better. Anyway its a another great little plane by WM.
