Thanks Geeby! I just tried out the calculator and it seems to be giving me odd results. The recommended power setup is way Under Powered.
This was for a 70" 3D HobbyShop Slick. Here is what I entered. 3D flight, 4 kg, 61.3 sq. dm and 8S.
The results were 1350 W. That is way to low for 3D 1800 Watts to 2200 Watts is what I expected.
Battery capacity was fine but discharge rate was off. It recommended a minimum of 15C where I don't think I would fly with anything less than 20C on that setup.
Propeller was also off. It recommended 15.8 x 7.8. That will not move the plane. The smallest prop for 3D for a plane this size would be an 18x10.
