RE: identify aircraft
For shure it is a Joker !
Wolfgang Matt designed it in 1984 and was EC in the same year. The kit was produced by MK until 1989 aprox. This one has not the original canopy and probably some minor changes. I still save mine with a YS engine, .61 2C long stroke, rear exhaust, hatori header and pipe, MK retracts
