Jeff,
Thats unbelievable! It is the Sig Kit. I started one in 1980 and I realized it was over my head so I sold it with the wings built.
I always regretted that decision and I decided to put it on my bucket list. I found it challenging but having spent 45 years in the RC hobby I’ve gained a lot of knowledge and experience. I will post pictures soon. Thanks for sending the pic.

Robert
