Update 27/10/2018: Added PDFvector plan tracing, thank to belli. Found online at this seems to be a faithful copy, although it does show modified tail parts for 2 channel RC, with hinged elevator and rudder parts.

Update 29/10/2018: Added CAD files, thanks to belli. This is a zipfile containing 2 dxf files, one with original layout, one with mods for RC.

Supplementary file notes

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

Hi Steve and Mary, I have included some pictures of my KK Scorpion, built in 2002 and still in one piece, albeit with loose U/C fittings and a rather oily front end [more pics 004-009]. In its time it has been powered by an ED series 2 "Bee", AM 10 and AM 15 engines. Although a bit of a "builder's" model it is well worth the effort and makes a great flyer.

* 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.
