Hi out there RCU pattern-experts, please help me to identify this pattern plane. Bought it some years ago second hand, the owner had no idea what plane it could be.

Fuselage is about 44" long, made from polyester resin cloth, wings are foam core covered with dark veneer wood, unknown kind, same as stabilizer. Wingspan will be about 51", wings are prepared for fixed tricycle landing gear.

Any hint is appreciated!
