need propulsion sytem
I have built my plane. it is about 15 pounds with payload not including powerplant.
Problem is i dont know a thing about powerplant. I have to use electric motors. I have it constructed with two motor mounts.
I really need help desinging a propulsion system. Two electric engines, 40 amp controller, props, and batterys. Money isnt really a big issue. need about 10 minutes fly time. must take off in less than 200ft. im thinking a good T/W is about 0.35 maybe.
please help

RE: need propulsion sytem
One suggestion, download motocalc.
The latest version does multi-motor and multi-battery calculations and offers a wiring diagram on how to hook it all up.
