>Mike Patey put a 680 shaft horsepower PT-6 and 102” four bladed prop on the front of the last Wilga ever built. With an empty weight of 2400 lbs and a typical flying weight of 3000 lbs, Mike can be off the ground in about 120 feet, pitch to 30 degrees and maintain 4,000 feet per minute... while accelerating 50+ mph by 1,000 feet! He designed a completely new airfoil that dropped the stall speed about 20 mph to about 37 mph.
