Syma Forum

I don't remember anything about that, but I do remember one of the old timers from when I joined did extensive testing on what batteries to use for best performance. According to his testing, two 150mah stock Syma batteries weigh significantly more than one 300 mah battery, and unless you do some serious weight savings, that big of a battery is too big and heavy to be effective anyway. I don't remember the exact mah rating of the ideal battery, but I believe it was in the range of 200-250 mah. I want to say 250 was where it reached the point where the weight was taking too much to lift, wearing down the batteries, along with the motors, and that it is equal to the flight time of a 200 mah battery, with the 200mah being cheaper and much, much easier on the motors and other mechanical parts. Thing is, that was two years ago now, so I don't remember the exact rating that was ideal.
