I use a lipo dapter (A123 version) with my astroflight nicad/nimh charger.

Charger was pricey so there was no point buying a new one.

I dont bother balancing the cells. Even with the abuse I have put them through they are never that out so I dont see much point.

Lol not 2 mags, I wish! No the magmotor in hornet is now made up from the good parts from two nackered magmotors, a frankenmag if you will
