Aircraft; Weather; Procedure
While practicing off airport; back country landings I experienced an unusual gust of quartering tailwind immediately following liftoff which destroyed lift and resulted in an impact with the ground.No injuries but substantial damage to the airplane. All required reports were timely made. This was in a large meadow on top of a butte with a slope up to the south. Landing was made to the south into the wind; uphill and uneventful except for a downdraft experienced on short final. This should have been recognized as a factor to be considered.Normal takeoff from this location is to the north down the gradient. Unfortunately on the incident day; the wind had increased velocity after our landing; a stop was made here. In retrospect; it would have been safer to takeoff into the wind or maintain more time on the ground to build airspeed with the downhill takeoff.Also; it is now clear that takeoffs with little or no bailout opportunities in case of problems should be avoided.
PA-11 pilot reported aircraft ground strike on takeoff which damaged the aircraft.
