I'm rapid prototyping a mounting bracket to add an AEG gearbox to the underside of my RC helicopter.
What I'm wanting from you are suggestions of what gearbox to purchase. I need the lightest and most compact full auto gearbox I can find. It doesn't have to be super quality and the smaller the batteries I can use, the less weight ill have to contend with.

Any ideas?

Thanks.
