Leonard, I live life on the edge I guess. I have never taken my Li Poly pack out since I got it over a month ago. Charge it in the plane and never take it out because the hatch is a pain if I want to take it out.

I use the Astroflight 109 charger and charge at 1C charge rate. I will stay somewhat near the plane when I charge but I leave it in the garage with the plane.
