It's horribly top heavy! The first one I built by the plans, I changed the name to SloRollover.
I redesigned the whole plane, changed the fin/rudder, size and shape of the wings, longitudinally reinforced the fuse with full lengths of 9mm EPP and moved everything electric towards the center line and CG.
NOW it does everything well besides hover (which it didn't do that well either, since it was top heavy and kept tipping over and rolling out and you had constantly fight it with with all the control surfaces.)
I've since gotten bored with it and moved on to an Ultimate 200 BiPe I designed from scratch. The Alpha model flew nice, the Beta is just wrapping up final fine tuning, then on to the final version - pretty accurate to scale, flies fast or slow, 100% 3D and still does VG pattern. It has wheels too.
Live and learn, it's what life is all about.
