I have seen mine bounce off teh ground and not break. The battery it comes with is a 7 cell 8.6V nimh, but if find it to be a junk battery. I have less than 20 runs on the plane and the battery has shown significant loss in performance and duration. Hopefully sometime next week that problem will be solved as I ordered acouple elite 1500mah packs from Cheapbatterypacks.com. If they are way better than the stock pack like they were VS the pack that came with my Mini LST2 the plane should have gobs of power on tap.
