RE: New SV Gassers
The chinese engines are not in the same class as the bid dollar engines, and people should not be using them for competitive flying in the first place. They are just nice little sport flying engines, not state of the art high performance, competition engines.
I have a Great Planes Super Stearman that weighs 16 lbs, and my SV26 pulls it wonderfully, always starts right up, and runs like a dream every time. Sport flyers like myself don't need state of the art performance, just nice little dependable engines that run smoothly.
