A new version of the X4 with proper battery pack would be sweet esp if they can go closer to the 1hr mark, but even 40 min would be cool. I briefly looked at the current X$ sometime ago and the lipos all janky like strapped together was a turn off, if only for the reason of having to charge a bunch of them later. SP140 nails it; plug and forget.
I absolutely love the idea of easily breaking the motor down to fit in the back seat of a car!
