The more battery you have the more weight you have. A 4000mah should give you around 10 minutes of mixed flying.

The prop suggested on the site is a 12x6 with 4s or 13x8 on a 3s.

If you used (2) of the 4000 mah packs, you would be hauling around almost 2 pounds of batteries.

You can always send me the O.S. .48 engine if you don't want it.
