Keep in mind as you outfit your plane that you pretty much get what you pay for in this hobby. For electronics and engines, buy the best quality you can afford without getting overly complicated. Airframes at the outset are 'expendable' and can be replaced rather inexpensively. But engines and electronics can usually be reused so it pays to invest in quality here. I still have my original trainer engine, a .40 size bearing engine, in an old timer I fly in climb and glide vintage contests. It's 17 years old, spent one winter buried in a cornfield and still purrs like a kitten.
