RE: home made electric motor
It's one thing to buy a motor KIT but another to make one from scratch. You need to cut out multiple pole pieces, make endbells with bearings and then make a commutator unless it's brushless and a host of other things. This is a "lie down until the feeling goes away" sort of deal.
Way back in my teens Lindberg used to provide little electric motor kits with some of their plastic airplane kits so you could make a motor and it would spin the prop. THe motor would barely turn itself over so this was only to turn the prop. Despite careful work I only got about 1/2 of them to work. Making a motor totally from scratch as you suggest is just way over the top given the price of super cheap and powerful motors these days. For sport flying you don't need the fancy brushless stuff and the expensive controller that goes with it. The GWS gear drive motors work great and there's pretty much a size for every occasion. And if you can find the little Johnson motors they work great on direct drive for about $2.50 each. Add on a Gunter prop for another buck and it doesn't get much cheaper than that.
Anyway this is obviously in the wrong forum. I have to move it to the Electric Universe.
