forgot all about a fast charge ! a fast charge would probably be ok once in a while, but definetly not for the first few charges. i just think it`s wrong for manufactures to advertise "ready to fly in 1 hr " or less just to try to get someone to buy their product. i built my first plane 20 years ago when there were no arf`s. it took days or weeks until it was ready to fly. now u can buy a arf for a little more than a kit. i really like them but i still build once in a while,probably 1 in every 3 . conk
