RE: Nitroplanes Piper Cub
Well, I maidened the plane a couple days ago. Although running the motor with the plane on the ground it felt like there was enough power, I kept wondering if this thing would fly well enough with this motor.
I had asked one of the more experienced flyers at my clud to maiden it for me, and he started laughing when the plane took off in a couple of feet! It literally rocketted up to the sky. It has unlimited vertical with this motor, which surprised me - not a bad deal given the price!
The total weight with the battery was under 2 lb. I tried to make it light so to balance it I had to put the battery right behind the fire wall, which makes installing and removing the battery somewhat challenging. But this way I only had to add 1/2 Oz to the nose to balance it. The manual says the CG point is 56mm from the leading edge, which is what I used and it works really well (I moved the CG very slightly forward but it probably wouldn't have been necessary.)
It flies really well.
