Graupner Extra 300
His looked really nice also and flew nicely for about 5 minutes.
I hope it's just a fluke, but the stab is fairly big and not air-foiled so it is doesn't have the thickness of an air-foiled stab sticking out from the fuselage. most flat stabs of any size are wired.
Good luck.
PS:
I wasn't being sarcastic about it flying good for 5 min.
It really did fly and track nicely.
