Currently I am thinking of using Li-po batteries. 3S 30C 11.1V 3900mah. Will this be enough to meet the requirements? This is a ball park choice as I don't know how t calculate what specifications I will need.
I also need to choose an electric motor for the plane.
Any help will be greatly appreciated, thank you.
What kind of model airplane are you working on?
IMHO, a 40 minute flight for an electric model will be very difficult to accomplish. (Read as expensive) That would be more in the area of a glow or gasoline powered model.
