if any of you guys out there buy one of these little quads for your kids. be sure to check the length of the bolts for the battery bracket. i had the bolts rub a hole in one of my kids batterys. lucky for me i bought mine localy and was able to get a free replacement.

i added some washers to space the bolts out. but you may also want to insulate the movement of the battery by putting some rubber tubeing on each side of the battery.
