If you think the plane is too expensive forget about it. There is nothing cheap about setting up a foamy for 3D. Brushless w/ ESC, lipos and mini receiver and servos will cost about $300 so the 20$-80$ you could spend on a plane is the least of your worries. Some will say you can do it cheap with a brushed motor and nicads but you won't have a 3D machine like you read about in the forums. My Foamy Factory blows people away at the field and I only have $20 into it before the electronics. When I tell them what it'll take to set up they lose interest real fast.
