Mach 1 - Mach I - Classic pattern plane.
Update: - "Model Airplane News continues its Parade of Champions with this latest entrant in the contest arena - imagine a plane that can win the Masters, Tangerine and Southwestern Champs in the short period of five months!
I don't know how much 'master-minding' really went into the design of the Mach 1, but I like to think that maybe a little bit did, anyway, especially in view of its contest performance record over the last couple of years. Since its introduction in the spring of 1971, it has placed first in nearly every sanctioned contest entered. Of the 12 contests entered during 1971, there were ten firsts, one second and one fourth. Since the end of 1971, the record is a little better. All contests entered were won except one, the Nats, where it placed fourth as it did the year before. Of course, the best win to date was the 1972 Masters in Huntsville, where the US FAI Team was selected. This win, I suppose, required what one might call a little bit of masterminding.
At first glance, the Mach I might look like a conventional design. However, closer examination will reveal several departures from the usual Pattern shop used today. The fuselage is 57in long and the wing area is 715 sq in, and that I think you'll agree is a large airplane in anybody's book..."

Did we get something wrong with this plan? That happens sometimes. Help us make a correction
* 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.
