I had one.Great fun .Flew much better than it looked!(beegee)
"The Plank" (well known red one) used to regularly go continental from Andrewsfield.
I believe the prototype did 32 consecutive loops.
As with any of the lower powered aircraft ( or I suppose ANY a/c) they are only as good as the engine installation but a good one will give excellent service and maximum bang for the buck.
