So I just got my DR-1 in the mail the other day. I've flown it seven times now and the last three flights have seemed really short. I timed the last one and the battery only lasted a little over two minutes. I'm starting to think I have a bad pack.

Out of the box the battery was already in the helicopter and connected. Even with an on/off switch isn't that a bad idea?

Also the pack seemed a little bent near the plug but I just assumed that was the packaging. It isn't crash damage - I've brought it down quick a couple of times but I haven't actually crashed it yet.

About how long should my flight times be?
