About this Plan

Mambo. Radio control sport trainer model. Wingspan 48 in.

The Sterling Mambo (oz4073) kit first appeared in the late 1950s. This here is a later CAD drawn plan from Bob Harris Models. Note this plan includes parts arranged for laser-cutting.

Note this plan appears here on Outerzone courtesy of the designer himself, Bob Harris of Early RC Models.

Note the primary drawing here is the CAD zip download (in dwg format). That's the file that Bob sent us, and that is his design, his work. The PDF file you see here is really just a taster, a PDF file in this slot for Oz users who don't have a CAD viewer.

Direct submission to Outerzone.

User comments

The Mambo was the first RC model I ever flew. It wasn't mine, but my buddy Al's. It didn't fly. At first. We believed the Sterling plans that showed how to modify the elevator position if you had one of the new "lightweight transistor receivers". That's what Al did. Big mistake. My excellent hand launch threw it right into the ground. Twice. Now this wasn't our first rodeo, we already knew how to make a model fly. Previous hand glides had worked fine. Later, advice from Ray Seay, one of my paper route customers, let us know what was wrong, which everybody but us knew. The plans were wrong, and should have been built without modification. It was tail heavy too, and a little weight up front made it flyable. Second attempt finally gave us success, but Al's anemic Fox 09 was barely enough to get it over ten feet in altitude. It ran well just not quite enough, despite our lightweight transistor receiver. A replacement Fox 15 made it into a rocket ship. Al's cure would have made Rube Goldberg proud, an added throttle control made from a rubber toothbrush tamed the Fox enough for controlled flight. In 1962, this was a normal part of radio control. We didn't care, we were Seniors in high school and could do anything. The Mambo did give us some success, we received our one (and only) "A" in English class where we wrote about it.

Notes

* 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.

Scaling

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.
