Angus Fleming bought the Chevvron 2-32 with a 45 hp Hirth 2 - stroke flat 4 to Halton to demonstrate. Knowing he'd considered the Mid West single rotor engine of the same power output I asked him about it and he said it was OK, but with an EGT sometimes exceeding 1,000 deg C it wasn't a good proposition.
