You may want to consider the Stik 40 Plus from Balsa USA. Price ain't bad. Simple build, about 1 step up form an ARF. And solidly built so it will survive some beginner's prangs. Worse comes to worse, they do sell wing kits. BUSA is a good company that has been around.40 sized 2 stoke or 50 to 60 4 bangers. Doesn't need a high end expensive engine and works fine with basic servos.Easy to convert to trike gear.Tom
