Steen Skybolt (oz10564)
About this Plan
Steen Skybolt. Radio control scale aerobatic biplane model.
Quote: "Exciting scale development of the famous aerobatic hipe that has won every contest entered, including a Fourth at the 1976 Nats! Steen Skybolt, by Bob Noll.
Everyone likes biplanes, and I am no exception. Stay with me now and I will introduce you to a top performer and a good looker, the Steen Skybolt, an exact 2-1/4 in per foot copy of one of the most exciting homebuilt biplanes around.
Designed by LaMar Steen of Denver, Colorado, the Skybolt is a high perfor-mance aerobatic biplane. It can be found with either a 180 hp or 200 hp power plant and a gross flying weight of 1650 lb. The Skybolt is not factory produced, but rather is homebuilt using detailed construction drawings available from the designer.
First, let me explain how I came around to the idea of building my Skybolt. During the summer of 1974 considerable interest was developing in the sport biplane class of acrobatic competition. In the fall of that year, I decided that I would rebuild a 1960 Astro Bipe (oz4674) which I had had so much fun with during the early sixties, until it sustained some major damage due to inherent difficulties of the 'reed' system that I was flying at that time. The Astro Bipe was a .45 powered semi-scale Pitts special designed by Fred Dunn in 1959. As for the reeds, if you don't know what they are you're probably better off, and it won't show your age.
As most projects turn out, what was to be a simple rebuild began looking more and more like a total redesign in order to accommodate today's larger engines and improve general construction qualities. About this time I discovered that my heart was no longer in the project which was pushed to the back of the workbench.
Then it happened! I took a Sunday afternoon drive to Endicott's Tri Cities Airport to check the winter flying activities and a beautiful full-size red, white and blue biplane was sitting there glistening in the December sun. A closer inspection revealed that it was the magnificent 'Skybolt' that a friend and fellow modeler, Hale Wallace, had just completed after three years of work in his basement.
You guessed it, my sport biplane project changed instantly to a full-scale copy of Skybolt N1HW. It had everything I wanted from sleek design to eye-catching color scheme. Those who know me, know that red, white and blue airplanes with stars just turn me on as witnessed by my Yankee design (oz8766) that I have been flying in Pattern for several years. Who could possibly turn down the opportunity to copy a plane that is hangared at your local airport, especially when you can borrow the construction drawings that were used to build the real thing?
It wasn't long before the previously mentioned sport biplane project was moved from the back of the workbench to a not-so-safe place under the bench and a new sheet of drawing vellum was stretched out on the drawing board. Before I knew it, the model design began to develop using the set of official Skybolt construction drawings that Hale used to build his 'pride and joy.'
As the design progressed I found myself more involved in this project than in any previous one, and the idea of creating a full-scale model began to develop in my mind. Just imagine doing snap rolls, inverted spins, reverse spins and hammerheads all with a smoke trail and a parachute drop for added fun, with a plane that can win first place in sport scale as well. If you, too, are turned on by such things let me suggest the Skybolt for a very satisfying project and one which will make you the envy of many other modelers. Show me a modeler who doesn't get excited by a biplane and I'll show you a man who thinks Farrah Fawcett is a new kind of spigot.
Construction. Although the construction of the Skybolt is not as simple as that of a foam-winged monoplane, it is however very basic, but should not be attempted by an inexperienced builder. With this in mind, I will not give you a step-by-step construction sequence, but will highlight some of the different features used in this design. Oh, yes, the first thing you should do is purchase a set of full-size plans from MAN.
Wings. The wings are balsa built-up construction. You remember - ribs, spars, shear webs and cap strips. Of course foam wings could be built, but that would take away from some of the fun..."

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

ScaleType: This (oz10564) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.
If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.
ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Steen_Skybolt
Wikipedia page addresses may well change over time.
For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

User commentsHi Steve, Here is another photo [pic 007] to add to the several you already have posted about my Steen Skybolt oz10564. It was taken at Tri-Cities Airport in Endicott, NY where Hale Wallace built his full size Skybolt.

* 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.
