Hi, I am just getting into rc planes and I need some guidence on buying the right motor, esc, and battery. I'm the kind of person who just likes to build things so I'll probably just get one or two sets of electronics and scratch build planes to put them in. Since I'm going to be using the same internals in multiple designs, I wanted to see if someone could recomend be a basic setup that I could toy around with. I dont really know what kind of planes I'll build in the future but Im starting with foam and will move up from there at my own pace. I don't have a huge amount of money to spend to price will be a factor. Any feedback would be greatly appreciated.

EDIT: I already have a good transmitter, receiver and servos from other projects so guidance on this isn't necessary.
