Thanks for the replies guys. Since posting this, i upgraded to a 3Cell 2600mah battery, and a park 480, turning an 11x4.7 prop. This might sound like over kill, but it's perfect. I never use full throttle, (since it would make with wing flutter). I can fly around much better with the aileron upgrade i installed, and and take offs at 1/3 throttlein the back yard are very scale looking. I can fly for 20+ minutes with this setup. I HIGHLYsuggest this upgrade.
