Quote: "Hi again Steve, As promised in my earlier e-mail, I am attaching a pdf drawing of 'Parts and Cutting Plan Layout' to accompany Outerzone Plan oz13239. At the time oz13239 'Champion' was added to Outerzone, only Sheet 1 of 2 sheets from the kit design was available. Sheet 2 would have shown the various component parts. I have drawn up the individual parts and a cutting plan layout, so perhaps this could be appended to help future builders? I am in the process of building this version and would hope to let you have a photo in due course. Kind regards, Jeremy"

Quote: "In the absence of Sheet 2 of the original kit plans and instructions this drawing has been developed by making a CAD tracing of Sheet 1 (Outerzone Plan oz13239) and drawing the individual parts. As the only clues to the wing and tailplane aerofoil sections used are those shown on the fuselage side view, these were used as a basis from which individual rib outlines were developed, making allowance for the angled ribs. A wing and tailplane were then built, with any inconsistences discovered then being corrected in the drawings.

On a practical note, a small change has been made to the original design to introduce Part F13A between the wing seat and the front wing retaining dowel to provide additional support for this dowel. Additionally, particularly if R/C is to be fitted, it would be recommended that an additional 1/16" (1.5mm) dihedral brace is added at the spar position although none is shown on the original drawing. Wing and tailplane ribs are drawn with a 2mm allownce at both leading and trailing edge to allow trimming to exact fit.

No details are available of the instrument panel layout or of the compass mount shown on the drawing as attached to the rear of F4."

Very nice. Has anyone got Sheet 2?
RMG - 15/08/2021
As it is a kit plan there may well not be a sheet 2 (I'm assuming you are expecting a parts drawing sheet). All the 'plan' build drawings are here along with some detail instructions. The angled ribs are the biggest challenge but even that is surmountable.
M Hodgson - 15/08/2021
Currently, this is all we have. No copy (as yet) of the printwood, the formers. Looking at this plan sheet, I would have guessed that was it. I mean, in the original kit the printwood plus this sheet would seem to be all you need? But you are right, it does say sheet 1 in the bottom right hand corner. Maybe sheet 2 was text instructions? Anyone out there can shed some light on this?

Lovely to see here, but with respect it is a free-flight model. Would carry modern radio easily though of course.

Doh, my mistake. Free flight, yes. Fixed tags now. Many thanks.

The note just below the nose section of the fuselage top view has a reference to Sheet 2 in "See sheet 2 for details of bearer spacing etc. for different engines"
Gerry de Groot - 16/08/2021
Yes. Also, now I see sketch # 15 in the assembly sequence says: See sheet 2 for cabin interior detail.
SteveWMD - 16/08/2021
I have a untouched kit some-where in the loft.

Well Richard? (Don't keep us in suspense - we'd like to know things like: what's the wing section, does your kit have a Sheet 2, etc, etc?)

* 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.
