Not trying to be sarcastic but if the wind flipped it over at an altitude of only 15 feet I doubt very much that you had time to do all the things you've described. If it was indeed inverted on you that low to the ground you should have simply pushed down elevator as you were more than likely already at full throttle. Never try to roll out of inverted flight that low to the deck. Once it got inverted (that must have been one heck of a wind gust), any aileron or rudder input is very likely to only worsen the situation. If you panicked and mistakenly pulled up elevator, well, that was over with in a hurry. Crashes suck any way you look at it, but try to learn as much as you can from it so it's not a total loss.
