but my worst plane to date is a SPAD. The SPA3D to be exact. When I considered building one everyone seemed to like them but all I got was a 3D plane that was way too heavy for any serious 3D maneuvers. I built mine exactly to the plans and the biggest problem with the design (besides the weight) is the aluminum rail fuselage is so flexible that the tail would always be a half turn behind the main wing while doing a roll. Handling was lousy at best.
I have a spa3d and so does my brother. mine has no fuse flex. but i can't stand to fly my brother's. it flexes so bad its scares me. and they WILL do 3d. i have a 6 year old tower 40 on mine and it will hover no problem...
