About this Plan

Fancherized Sig Twister. Control line stunt model. Kitbash of the Sig CL-22 Twister. 490sq in for 25-40 engines. Drawn by Bob Kruger 14 Jun 2002. Last revision 2 Jul 2005.

Quote: "HI, GROUP! Probably the most consistent complaint I receive on by monthly musings is that the material I cover is too 'high-tech.' While I don't feel that the CL Stunt column should be considered a beginner's forum, there is nonetheless a lot of merit to those complaints.

In response, I have undertaken a project which I at first thought would be a pain in the neck but which has proven to be both enjoyable and educational. I built me a Sig Twister!

Most of this and the next two columns will be a fairly detailed coverage of my experiences dealing with Stunt from the viewpoint of a beginner. Using only commercially available supplies and trying to limit a nearly uncontrollable urge to 'make things better,' I'm going to build, finish, and flight-trim a profile Stunter appropriate for anyone from a beginning pilot (not a rank novice) to an Intermediate or new Advanced flier.

If I've had any luck et all with the Instamatic, several pictures should accompany the columns. These will help illustrate some of the techniques and features. Let's get the hardware out of the way first. I chose the Sig Twister, kindly donated by Mike Pratt and Sig. I used both a Merco .35 engine from Tom Dixon and a box-stock OS .40FP, and I used a Taffinder four-ounce profile tank, modified for uniflo.

The hardware package included with the kit was used with the exception of the bellcrank, for which I substituted a Fancher Circular Crank to which I am partial. (There is no significant value in doing so at the beginner level, and I don't necessarily recommend it. I wasn't even going to mention it except that my fancy ballcrank caused some problems in the initial test flights, and I didn't want you to think it was the fault of the perfectly adequate Sig bellcrank. More on that later..."

Note this is a modern CAD-drawn plan in PDFvector format.

The design first appeared in Model Aviation 1986.

* 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.
