Converting Goldberg Anniversary J3 Cup to Electric

by Donald G

Hi,
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?

Thank you.

Carl Goldberg kits are old old kits that were built and designed to be heavy to offset the weight of old glow engines. This kit was designed for a 40-60 (.40 to .61) two stroke glow engine. So you'll need a minimum of an electric motor comparable to a .61 two stroke. An E-Flite Power 60 should be a good starting point.
