she def gets nose heavy with a newengine on it, i put a evo .46 on mine and it was extremly nose heavy, if I could do all over again I would have just moved the battery behind the servo tray, but instead I took 2oz o lead and stuck them on the bottom of the stab right up against the fuslage then i took two screws and secured them, it flew great till I got a bit cocky with her.........may she rest in pieces. good luck
