About this Plan

Delta 16. Rubber powered delta from Frog. This is a tiled plan.

Note photo of completed Delta 16 was found online at the excellent House of Frog site at: and shows model made by Sidney Higgs.

Planfile includes full build instructions.

Quote: "This is a model of a modern fighter aircraft, based on the latest military jet aircraft to go into service with the RAF, and is airscrew-driven (by elastic bands) to simulate a prop-jet drive.

The model Is quite simple to build incorporating novel construc-tional features, which also make it very robust when completed. All the main parts are ready-cut to shape and numbered to correspond with the drawings, as in all Frog Kits.

To ensure a satisfactory job, study the plan and check the parts with it before commencing. Assemble the model step by step as described.

Cement and dope are not included in this kit, but they can be bought at any model shop. Use quick-drying balsa cement such as Frog Universal. You will also need a balsa-cutting knife or a razor blade and a few pins.

When you have built this model, remember there are many other Frog models equally attractive, which you will enjoy building.

Fuselage: Commence by pinning 1/8 x 3/32 balsa strip over plan (shown shaded) also cement together Fin parts 6 and 7, and pin over plan (see Fig.1). While the Fin parts are setting remove all bulkheads and parts 8 from panel, then cement half bulkheads 1, 2, 3,4 and 5 to keel. When dry add part 8 and three 3/32 x 1/16 stringers as shown in Fig.2.

When this half of the fuselage has set, remove from plan and add the remaining half bulkheads, part 8 and stringers. Nose rings parts 9 and 10i may now be fixed, cement these to bulkhead 1 with the grains of the wood at right angles to each other.

Cut an 8-3/4 in length from the 1-1/4 x 3/32 (wide) strip and set aside for trailing edges of wings, use the remainder of this strip to fill in between bulkheads 1 and 2 (see Fig.3). The sides and bottom between bulkheads 1 and 2 can be covered with stiff paper after fixing front undercarriage leg. Sand nose of fuselage to shape when dry.

Next bend the front undercarriage leg to the shape given on drawing and cement it in place on bulkhead 2 using a piece of scrap balsa wood to hold it in place (see Fig.3), use plenty of cement..."

Update 13/10/2020: Added ribs file, thanks to rchopper56. These have been redrawn from scratch.

Quote: "Hi Steve and Mary, It took me longer that I expected but here are the Delta 16 wing ribs that should work. They are all in the same family and (I hope) the correct length and height. Gene"

Update 12/03/2021: Replaced this plan with a single sheet version, thanks to DerickScott.

Direct submission to Outerzone.

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

The templates for wing ribs W2-W5 are not included on the plan. Or am I just missing them somewhere?

The ribs are not shown on this plan. That's why we have tagged it as 'formers incomplete'. It's a plan from a 1950s kit, and the ribs arrived in the box as printwood for you to cut out, so they are not shown on the plan. If you follow the link in the AboutThisPlan section to it says: " will have to draw up most of the ribs yourself. The shape of the root rib is given, and you can measure the height of the others from the front view, so this should be enough to work with. The sketches indicate that all ribs were flat-bottomed, with no reflex built-in."

I am curious where the center of gravity should be on this model? I don't see anything on the plans to indicate where it should balance.
Also, curious if anyone has built it without the landing gear and whether that messes up the center of drag.

About the C/G, see:
What I could read the result should be on the safe side, a bit forward. Next best thing would be a little card model with the same proportions. Words like 'Wurzelrippe' etc. can be found by Google for instance.

* 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.
