Slingsby T.49 Capstan (oz7184)
About this Plan
Slingsby Capstan. All-sheet radio control scale glider model. Uses a Jedelsky wing construction.
Quote: "Light rudder-only glider based on the Slingsby two-seat trainer by Jack Headley. The Slingsby Type 49B Capstan is a simple wood and fabric training glider, with side-by-side seating, intended for all stages of training and glider club flying. The simplicity of line was one of the things that attracted us to this model, together with the wide cockpit area which provides ample space for all the radio gear.
Our model is a simplified version of this design, for single-channel radios, including galloping ghost types. Also included on the plan is another version of the design, the Type 49C 'Powered Capstan' - a standard Capstan with a 45 hp Nelson engine mounted on a pylon above the wings. This type first flew in 1968.
We used an 020 engine for our model version, and this unit provides almost scale type performance. If you make the powered version, don't forget to use fuel proof dope when finishing the model. (The following construction notes apply to either version)..."
attached is Jack Headley's Capstan from American Aircraft Modeler magazine issue 08-72.
Direct submission to Outerzone.
NOTE ----- Correct wingspan of this plan is not documented. This version here is scaled to a 53in wingspan. Let's be honest, I can't remember the last time theshadow was wrong about anything.

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 (oz7184) 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.
Notes:
ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Slingsby_Capstan
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 comments
I got a copy of this plan via a friend in the US not long after it was published. It flew quite well for him but mine had a nasty habit of tip-stalling if it turned too quickly. The wing was trashed on its last 'arrival' so I rebuilt it with about 5 degrees of washout in the last two ribs to the tip and it then floated around really well. Then he told me, he'd done pretty much the same himself,.. from the start. Now that we have micro servos, I'm going to build another with two channels. As the plans are very easy to adapt, I might also scale them up slightly and possibly add a simple air-brake on the inboard section of the wing. This is because the last one also seemed to float along the ground at about 9" height before it found sufficient grass to snag its progress!PeteBraven - 04/02/2016
I flew the full-size prototype Capstan in 1964 at the Scottish Gliding Union's field at Portmoak. If my memory serves me well, its wing did have perceptible washout. I remember that it wouldn't stay in a deliberate spin for more than a couple of turns before the inboard wing un-stalled itself and you were in a fully controlled spiral dive - most reassuring!

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.
