Thanks trailingedge, I guess I'm pretty much a beginner... I just graduated college, and picked this up as a hobby... I think I have a major addiction coming on. I always wanted to fly RC planes, but never had the money in the past.
Start with two strokes, the advantage of four strokes is subjective, some prefer two strokes. They cost less and you will have less lost in a crash. I would try a .75 Tower or .74 Fox for the larger engine. I have no idea how small you want the smaller engine. .15, .46?
