I've been flying this plane for about 4 months now. I renamed it a flys funny instead of a 3D funfly. I crashed it twice due to the fact that you tend to fly it on the hairy edge all the time. Kinda like you get what you deserve! I have rebuilt it recently and made some pretty effective modifications. I removed the wing tips and made the tail completly over. It now has a much larger elevator and rudder with countr balance built into them. I redesigned the fin to allow more support to the fuse. I also added struts to better support the stab and fin. I have a honking Enya 50SS up front and am using the 12.25X3.75 APC prop. THe planes does alot of unbeleivable undescribable stunts but the thing I think is does best is harrier landings. Srap the POS landing gear and put a big pair of wheels on.All in all for the money shes a blast to fly. Mine weighs 3.9 pounds and I too have the cg at 4.5". Good luck with yours.
