My PV2+ must be a lemon. Sent it in August 20th, returned November first week of November due to it's instability and dropping like a rock for no reason. I haven't been able to fly it much due to safety concerns with it crashing down on something or somebody. It has a crash rate of specifically of losing altitude of about 1 out of 3 flights. It flies great until it decides to drop. Today I was at about 250' and was slowly descending using a somewhat gentle see saw lowering technique to avoid Vortex Ring State when it suddenly started the familiar wobble at about 150' until it crashed on the side of a bridge, hit and bent the gimbal which was generously replaced under warranty on the mentioned repair by DJI. Also they replaced the main controller and two motors. The crashes occurred on the current rollback firmware but not with the shortlived 3.?. Does anyone have an idea of what could be causing this problem? One thing I've noticed is that all crashes have been when the battery is less the 60% Today it had 12 satellites It's never crashed on it's own above the 60% battery level. So I'm wondering since this was one of the first to come out, (pre ordered) is it possible that I have 2 bad batteries? Something else? I give, I want to upgrade to the new Inspire 1 but if they are as bad as this one I can't commit to one especially since it's around $3,000 with extra batteries etc.
