I have a Pegazair that I built from plans . Tapanee also sells kits.
I put a 0320 in mine , Tapanee has a up dated plane to up the gross to 1850 that may not be on their site. Their small but great people and great planes!!
While the tail is some what of a copy of a 701 thats about all that is .
It is a great plane and you about have to fly one to understand.
A few years back Eaa had a write up on a 801 with a 180hp 0360 in it. If that write up was true then My 160hp Pegazair with 2 people aboard will best the 180hp 801 with 2 people in all ways by a fair amount, thake off, cruse, and landing .
Check it out!!
