Well,All these folks have some great ideas,I guess I'll put my 2bits in to I had a Super Chipmunck and that was a inexpensive arobat,it does pretty good 3D and flies strait and does great at high speed. Mine was a .40 but i'm kinda crazy so I put a O.S. .91 in with a.p.c.13x8prop
best cheap plane i ever had (don't let your friend crash it for you[&o]) so for $100 bucks give that a try I ordered another one
Happy hunting.
