Are you do is buy 4 picture clips, used to hang pictures with. I will give you a piture to look at, so you will know what size to use. Put 2 piture clips on each side, put the clips in the top and bottom groove. It is where the regular battery clip fits at, do that to all 4 of them.
When i tryed it, it looked like it made it react faster to the motor, made it pick up a bit faster. The only problem is taking them off and Back on. Plus they dont weigh as mush as the stock battery clips do.
