About this Plan

Comet Clipper. Free flight gas model. Classic design. This seems a modern, faithfully hand-drawn copy of the 1930s Comet design, here drawn by A Kreiger. This version of the plan includes the wing ribs.

Direct submission to Outerzone.

Pic is from an ad in May 1939 Air Trails, thanks to JeffMac.

Update 29/02/2020: Added zipfile of CAD drawing of airfoils, thanks to Edson Nóbrega. (includes 3 files in dxf, pdf, cdr format).

Quote: "Hi Steve. Here are the files. On the right side the airfoils are ready, just apply a scale to adjust to anyone's project. I also attached the files in Corel Draw in case anyone wants to edit them in that software. The profile flows smoothly between rib 1 to rib 9 and smoothly from rib 9 to rib 18. At the root is under cambered, the W-9 is flat at the bottom and the tip is symmetrical. Regards,"

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

The airfoil is incorrect. the comet Clipper, by Carl Goldberg, Has a under cambered rib at position 1, a flat bottom rib at position 9 and a full symmetrical at rib 18. The lower airfoil curve is designed to flow smoothly between rib 1 to rib 9 and smoothly from rib 9 to rib 18. The top airfoil curve, at maximum height is a straight line between rib 1 and rib 18.. i was a friend of Carls and produced the P&W Partial Kits. John Pond made a plan for the 10 foot Clipper Mk 1 that showed the airfoil under cambered from rib 1 to rib 18. This is not an accurate scale up!!

* 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.
