I'll have to agree with you Steve..I had two original Bridi Kaos' and an original Sun Fli 4 and one outstanding trait of both designs was the ease and smoothness of the landings. I'm putting a new Webra Speed 61 on this one so power should not be an issue.
All the Sun Fli series are SPA and CPA legal...the SF4 was designed in 1969 .
