New P3A owner here ... let me just say the thing is awesome. My only regret is not getting one sooner, as I have a lot to play around with and learn about these things. Apologies if this one's been covered already, but what are some best practices for charging the RC? With my batteries, I've of course been charging them after my flights. I've also been fully charging / topping off the RC as well, just for the hell of it, but am wondering if I really need to. The gauge has always indicated 4 bars (that I've noticed anyway). Do you guys go through several MR batteries before charging your RC? Or do you charge RC whenever you can?
