RE: LI-FE battery pack, good or gone?
Oh there's still a place for the Nixx technologies. Both are still tougher than lithiums and don't require balancing. I'm a big fan of LiFe, but even I don't recommend them for beginner pilots.
Warjet, I see you're from my driver's hometown. My 5 year old daughter named he puppy "JJ" because of him. Are you expecting the see the 6 pack this year?
