Just might be an issue as so many reports surfacing on the landing gear, tho in my case will readidly admit I came in way to hard and a bad angle, several landings since several hop skids but holding fine now. The stock battery on mine fits like a glove and the extra slightly smaller 2100 battery has some extra room but I just use a small packing in the strap to keep things inplace. Mine is very close to correct COG right out of the box with the included battery. Find the handling on this one is exceptional, I like it. This one moves out abit faster and just might be part of the delemas. Giving this one more room on the approach solved my earlier landing problems. I'm not gifted on landings, but otherwise having good luck todate. BEST ..<>...
