I downloaded plans for the EZ-400 ( Eee-zee-400 ) from here. I must say, this is simply a great flier! What a treat! It's fast, build it and check out it's roll rate!! WOW! I've flown mine a number of times, landings are quite hot, unless there's heavy wind. It flies inverted as well as it flies right side up. Aileron control is simply +ve, great high speed turns! I love this model! Climbs out at 45°! Immense climb... what are you waiting for...go build one!! Long flights are possible. A flight full of aerobatics will last about 6mins, just cruising along can give you 8-10mins.
