I flys nice stock but it is a lot funner with a 5 cell battery instead of the 4 cell pack. I had some loose 270 mah batteries and made a couple of 5 cell packs and had a lot better climb rate and power. Plus it handels a bit more wind with the extra cell. Check the control wire about every time you fly because they seem to like to work there way loose.

For a little better turning add a 1/2" of foam to the controls on the tail. The bigger surface give a little better control.
