Im far from a seasoned ace in them myself (thank god), flown just 2 of them and they both sucked. (fixed gear musketeer I'm referring to)
The 200hp one wheezes its way to 105-110 perhaps and struggles to get above 4500 feet on a warm day with 2 people and gas...
When I compare that to a Mooney or Cardinal and what they can achieve with the same horsepower I wonder why they bothered.
