RE: 9CAP battery
I made my own battery pack for my 9C using shrink wrap and battery tabs from radicalrc, and some 1850 mah nimh batteries I bought from Walmart for $9.48 a pack (4 in a pack - and you need two packs). I used the old connector from my 9C battery, and soldered all the batteries together so that they looked just like the old pack. The new pack works great - and it has much better duration! When I was done with that - I took the original nicad batteries from my 9C and made up two 700 mah nicad flight packs!!! I spent about $23.00 making my own - plus I ended up with two more flight pack batteries!
