Hi Greg, I just want to stress it is not very safe keeping Lipo's in your pocket. The exposed contacts of the micro flyer battery could easily short to a loose coin in the pocket. It is true it's best to keep Lipo's warm but we can't underestimate the damage these things can cause. I bought a micro flyer because of the videos on your website. Have you flown it indoors yet? Do you plan any modifications to your MF? I am thinking about converting mine to work with my JR radio.
