I would call out to Dessert Aircraft I have a DA-50 on order. When I talked with them Last friday they were doing some test flights with a 31% plane with unlimited verticle !!! This may or may not have been the aw 31%. But they quoted me some very impresive numbers and said this will outperform the g62 and in the same airframes would prove to be a better engine combo (more power and less weight)
