I have not flown one but I am helping with a rebuild. My impressions is of a typically British built aircraft,well over engineered.For a light aircraft it is far to complicated and not much fun to work on. Parts are a problem. A guy in the US holds the rights to the aircraft and doesn't like letting go of any of the draws.So getting any thing other than service parts is difficult.The aircraft I'm helping with is fitted with the Hewland,which I am told has stopped once or twice in flight. I'm told its nice to fly and if you can find one with out the Hewland engine it might be worth it. Saying that the guy who designed the engine is able to rebuild them. But I would advice an extensive survey as they are getting a bit old and as we have found corrosion has started to take hold
