Be very sure the batterys have been stored OK and charge UP Ok too......id check the battery level closely for a few flights...Be sure they are charged to 100%. and let us all know how your doing ...Happy Flying !
I charged the batteries right before flying, they both showed 100% when I took off. I only flew once with one battery for about 12 minutes and then landed but didn't shut down. While I was talking to my neighbor I got a warning that I was down to 30% power. I think everthing is good with batteries. Here's a link of an edited video I took. I was looking at a red tail hawk nest that produced two chicks this year, they're gone now.
