The pilot reported that he was taking off from a private dry grass airstrip that was slightly uphill and into a slight wind. As the airplane accelerated, the pilot had "increasing trouble keeping the airplane from going left." The airplane departed the airstrip to the left and collided with terrain and hay bales. The airplane sustained substantial damage to the left wing. The pilot reported that there were no preimpact mechanical malfunctions or failures with the airframe or engine that would have precluded normal operation.
