So I bought a new battery...

It fits in the same tray I'm using now which is a big plus. It also shows how far LiPo tech has come in the last year... The old pack was 3300mAH 25C and was 160x44x50mm. This new pack is 4200mAH 35C and is 137x43x46mm. I am counting on the extra punch to make starting the outrunner easier.
