Yeah. 2 lbs is a lot of weight to add to that plane. My EMax GT 4020/07 weighs 8.8 oz, and I use an ICE 75A ESC @ 2.3 oz, and 5s4000 mah lipo pack weighing 18.5 oz. I put my lipo just forward of the battery box rear and it balances well at 4 - 3/4". I balance my aerobatic planes so the nose is slightly down on the balancer, not a steep nose down.
