I found my biggest hindrance to electrics is the learning curve. There is only one other guy that flies brushless electrics at my field and he flies much bigger, glow conversion type stuff and I havn't had a chance to talk to him about it. I can't tell you how many hundreds of dollars I spent on batteries, chargers, and motors until I found a combination that works. The absolute FIRST THING anyone should do is get a copy of motocalc and buy a decent hobby charger capable of charging lipos (they are available for around $50 now and are useful for much much more than charging flight packs)
