Me and TManiaci found a way to mount the batt. pack father back. What you do is, with some scrap foam You lay down a piece on both sides and you keep on layering it untill the two sides come up level with each other and lay a peice of velcro across from the first compartment into the second compartment so that you have a nice level area to slide the battery back into the second compartment. Thus allowing you to get your hell raisers C.G. back farther. With this I can get perfectly level inverted flight( with hardly any down elevator) and regualr flight. as well as extreme 3D manuvers. It is difficult to do this with an already built plane. We did it while every thing was still in pieces.
