Just picked up the Electrafly setup for Lipos- Polycharge, balancer, and 1250mah battery. The battery seems huge compared to the stock one, but it is the same size as the 910mah that Tower recommends. All I can see is hanging this joker from the underbelly- otherwise it wont make weight and balance. Where are others putting these big packs (I know that the Thunder power is not as big)?

On another note: You might think that products within the same line/name/family would be plug and play with each other, but not so with Electrafly charger and balancer. Had to change plug ends to make them work. Not a big deal, but unexpected and had to make another trip to the hobby store.
