Chris,
That is a model I build from magazine plans in the late 50's. I think it was Flying Models. It was called the Crusader. It was considered a stunt trainer. It was the best flying control line model I ever built. I also had a Nobler and a Smoothie. Both on them lasted about 1 flight. There was also a stunt model called the Crusader about the same time that someone flew in the Nats. It was a twin boom plane. Can't remember who flew it. I might have a picture of it somewhere. Fox .35s were the engine at that time.
The pictures were taken so I could prove to AMA that I had the AMA # 5646 so that I could have it again when I started flying again after a 25 year layoff. Most people with 4 digit numbers have them because they are CDs. 5646 is the number I received when I first joined AMA in about 1956.
