Gizmo, they done got smart and offset the stopper in the tanks now too so most of the tank is above or below the stopper. That way the center line of the tank can be more easily in line with the carbs. Tailskid, is that a 6V 2000mah pack? I'm now sold on the LIFE packs for rx. They are about half the weight of a Nimh pack. My GP Razor 3d had that canopy problem too. BTW, the Razor is a fantastic 46/55 size plane. I have the 55 inverted with a Mac's black profile pipe on it and it screams.
