Thanks guys, so I keep the amps down to say 3 or so?

I am only using the one Smart Fly fail safe switch to take the 18 g deans to the power expander in the 35%.

On my EF-88 I did my 2 cell A123 at 5 amps after a day of flying and put 699 mAh back in in 10 minutes flat.......before I could break down and put it in the trailer, done! That was after about 5 flights at 10 or more minutes each. Cool stuff.
