Brooklands I think you'll find that the 152 US built Aerobats have LESS power than the Reims built 150 Aerobats cos they had the 130hp O-240 engine in them. However, I think there are one or two US built 150 Aerobats around with the 100hp O-200 though.
The only aeros I've flown have been in an Aerobat and I thought it was loads of fun. Also nice to be doing it in an aircraft that I was already familiar with. The 130hp engine was a real bonus in the climb.
