User commentsI had one of these when I was a member of the USAF. It was a beautiful kit, all machined parts and no die-crunched sheets at all. The fuselage sides were unusually thick, with grooves cut into them to accept the formers, not possible to build it crooked. My radio, however, was a piece of crap, a Citizenship APS analog unit that left a lot to be desired. It suffered from a serious range problem, finally solved by mounting a vertical music wire whip antenna just behind the wing that flopped around like an old CB radio antenna. The servos never really returned back to neutral position very well, and I was unable to make a good landing that didn't bounce. I went back to single channel after that and didn't enjoy a decent radio until 1968 when I paid 300 non-inflated dollars for a good PCS system, a private label made by Kraft. You can imagine how long it took me to save up that money when I got paid 68 dollars every two weeks.

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
