Yes Ian. It was built by John. To me, it is a 4 cylinder Sierra, but he calls it a Cheetah. He added a fair bit here and there, including flaps, and it came out at least 50Kg heavier than mine, but still climbs really well and cruises at 110Kn. It is a very nice aeroplane.
Not a bad flight envelope - stalls at 22 knots and cruises at 110.
