Quanum Trifecta battery holder

This is a remix of Ares1's battery box.

I was annoyed by the battery strap provided by Hobbyking along with the frame, the batteries just didn't hold well. So I wanted to use the more common 20mm loop straps that work much better.
Since I use 2200mAh batteries, I also extended the flat area towards the rear.
Fixation is much better now, could probably do flips and more acro stuff without being afraid of loosing the battery :)
