About this Plan

Rodeo. Radio control sport biplane model.

Quote: "A realistic semi-scale biplane that is pretty in the air, steadier in the wind than the average monoplane, and fully aerobatic with a .35 to .61 engine.

Do you feel like a change from the usual aerobatic low wing monoplane? Are you apprehensive of the time and effort involved in building that scale model you've always promised yourself - and, even if you did build it, would it be 'too good' for weekend flying sessions? Do you like your models to look like full size airplanes? Above all, do you like biplanes? Then why not get some romance into your aviation with a vintage bipe, particularly the open radial motor, golden age type airplane of the 1930s - that exciting era in aviation history. 'Rodeo' offers you a fairly simple to build, yet realistic semi-scale model, based on the lines of these classic American biplanes_

Pretty in the air, delightful to handle, and fully aerobatic when called upon, it requires only moderate power (think of the fuel economy) - the prototype performing very adequately on a good .35 (Merco). Nevertheless, the model is large enough to handle a .61 should you really want to tear the strip up. The take-off is very straight and easy. in fact, the pilot is hardly involved. "Rodeo' ' just looks after herself - (I know you have heard this one before, but this time it's true!)

The approach and landings are really a dream - if you can't put this one down. you'll never land anything' You can haul it back with a link steam on and she will sit down, in a light breeze, with virtually no forward sriccd. at all. One of the features of "Rodeo" is its resistance to tip stalling. I wouldn't say it couldn't tip stall, but we've tried, and we can't! There is nothing fancy about the wing design, the airfoil section is NACA 2412 throughout, with the top and bottom wings at the same incidence, with no washout. And don't let anybody kid you that biplanes are tricky to fly in a wind, those who know will tell you that they are probably steadier in a wind than the average monoplane.

Having now come to the end of the commercial, let's have a look at the construction. In general, Rodeo is of all sheet construction, with cantilever bolt-on wings of balsa covered foam. The structure is conventional and simple and designed to use medium and soft stock. The selection of light wood for the sheet components is important, especially for the rear half of the fuselage, and covering of the tail surfaces..."

Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

User comments

The RCM&E plan for Rodeo wanted here, because it shows the open structure wings alternative to the foam wings. In the RCM&E article, it says quote “As an alternative to foam wings, open structure wings are also shown on the plan.”

* 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.
