Guys, I need help!!

I've been flyin' my Flip 3D and I'm not really impressed at all. It's super light and I'm using a West 50 T1 for power w/ an APC 13x4W.

1) I can't get it to hover easily. I falls off to the side and I try to catch it w/ the rudder/throttle, but it's too much of a struggle.

2) Harriers are really sloppy. Takes alot to get Hi-Alpha

3) Knife edge really sucks w/ this one. Pitches violently towards belly in either direction.

4) When I stall the Flip at a low throttle setting, the nose pitches down at about 50-60°

*My CG is at 6½" (w/ no fuel in tank)
*Max Hi-rate throws w/ 60-70% expo
*JR DS811 on all surfaces
*Flying weight 4lb. 11oz (w/ no fuel in tank)
*CF pushrods on all surfaces for stiffness
*Wing tips have NOT been removed

Could this be a CG issue? I'm kinda' afraid to move the CG any further back, because landing is now becoming a mission. Or should I continiue to move it back 'till I get the results that I'm lookin' for?
