Converting Goldberg Anniversary J3 Cup to Electric
by Donald G
A friend gave me an old Goldberg kit for the J3 Cub. I have built the plane but can't figure out what servos, batteries, motor to use, although a few online sites suggest a large brushless motor with about 1000 to 1100 watts. The rest of the electric is proving difficult. Plane will weigh in a just over 8-pounds.
Do you have any suggestions for this effort?
