Hey 9116 flyers,
I have come up with a wonderful and relatively inexpensive upgrade kit for the 9116. I have the xtreme 180 pro motor with ball bearings, I am running an xtreme 850mAh 25C 7.4 battery and last but certainly not least is my pride and joy a tail motor that took quite a bit of research and testing to discover. This tail motor is so powerful I cannot get this bird to sway her tail even if I punch it from standing still to full throttle, she just lifts into the air. I wanted to share so I put a few on ebay. I do the full upgrades on my repair site rchelicopterrepairservice.com check me out!
