I didn't say Dans packs are junk, Just said be careful Gearing etc due to the 15C.
I still have few of Dans packs and I concur on the under rateing, but you have to play it safe with all that weight.
Heres where a LOT of memebrs including myself have purchased Lipos from, the prices are great and selection is through the roof.
They also have 2.4 radios for under $40.00, not a typo !
