But like I said - the best setup I used was 7 cell 700 mah nicad. Try the above link and look for N700AAC. They will build you a pack for 5 bucks extra and i think a jst connector installed is 3 bucks. Good service from these guys. My all up weight with the 7 cell nicad is 17.5 oz and it flies like it's on rails. Original motors have 20 6 min flights and they are still going. I would go with lipolys but my funds won't allow a new charger and the cost of cells. Besides there are still too many horror stories for my own comfort! Good luck and let us know how it goes!
