I had one some years ago , good plane (dont think you get kits any more) what motor , I really dont know but I think maybe its a bit narrow in the nose for the new Hacker Q80's so I think any "normal" outrunner will do, maybe some off this "not" competiton Hackers or the Himax 210 it depends on you budget.
The plane I had was sold to a nice guy i Stavanger and its now over 10 years old and has around 800 flights and as I know still going strong.
