About this Plan
Polydi. Rubber duration model.
Plan includes full building instructions, and flying notes.
Quote: "The Polydi 40 inch span duration model. Building instructions. Build the isdes of the fuselage direct on the plan, the one side directly on top of the other. When cement is dry, carefully separate. Cement and pin the balsa nose former in place and pinch the tail end of fuselage together. The crosspieces are now measured from the plan, cut to size and cemented in place, see plan for details of all other fitting. To make wing, pin spars to plan, rasising front spar slightly to allow for the undercamber..."

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

User commentsHi Mary & Steve, There's something strange here. This is a "Keil Kraft Kits" plan, released at the same time as the Junior 60, in 1946. If you look in the bottom left corner of the plan, "Keil Kraft" has been deleted, just leaving the word "Kits"! Also, the KK address is mostly deleted, just leaving the "E2" as the end of the Hackney address. Why would anyone delete all reference to Keil Kraft from the kit plan?

Excellent, thanks Brian. Have listed this now as a Keil Kraft plan. I wonder if the simplest explanation is maybe there was a tear in the paper, and that part of the plan was just missing when the plan was scanned?

I've had a quick look at the original DBHL scan: I can see the plan was torn before it was scanned, hence the missing bits. OZ would never remove any info that helps identification. And theshadow is ... theshadow: a skilled restorer and beyond reproach :) He would never delete material.

* 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.
