OK, you have the DBS2 version, not the MaxxRange version. The DBS2 will work fine in the ProCraft or TT Helipak backpacks. As for the MaxxRange, I see no way to store that in a backpack with it installed on the RC, even if you removed the flight batteries to reconfigure the backpack. However, you might be able to figure out something if you detached the MaxxRange antenna using the quick-disconnect clips, but leave the cables attached. With longer cables this may alleviate the hassle of screwing and unscrewing the cables to the RC each time you fly. I'd never want to screw those cables on and off all the time, as many times as I fly. It's just too much hassle, slows me down. I don't have the MaxxRange to play with, so maybe someone else who has a ProCraft backpack with Maxx Range antenna can work on that. I personally don't think it's doable, given the size of the MaxxRange Itelite antenna. It's pretty darn big.
