hi guys need your help. just finished putting on the "superskids" and did a dual tail motor mod. got it all put back together and the tail is waaay too heavy. it drops alot. in order to balance it i would have to put the equivalent of a battery pack on top off the 3 in 1. is this wrong or should i have to add this much weight? if anyone has any suggestions i would be glad to hear it. hate to think i would have to get rid of the dual tail after just getting it on. thanks
