Need help choosing battery specs
Hi I am new to wattflyer and am looking for advice on my RC that I am building.
The maximum weight for this plane is 5kg and it is required to fly continuously for 40 minutes on a single charge. Based on these weight and flight time requirements what specifications for batteries should I choose?
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.
