About this Plan

DeHavilland DH-4. Free flight scale model, for rubber power. Wigspan 22 in.

Planfile includes full build instructions.

Quote: "Build the fuselage side frames on the shaded layout of the fuselage ide view. Use wax paper to keep framework from sticking to plan. Use stright pins to hold the strips.

When side frames are dry, glue former F3 between the side frames. Now glue back ends together. Glue former F2 in front of F3.

While that is drying, cut the crossbraces you will need one of each. See note near fuselage. Glue these formers to the side frames. Look at the top and side view to see where they go.

Trim the 1/32 thin balsa nose section so that it fits between formers F4 and bends nidely around them...

    ScaleType: This (oz352) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.

    If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.


    Notes:
    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Airco_DH.4
    Wikipedia page addresses may well change over time.
    For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.

I always enjoy an aircraft with a story behind it. Comet Models DeHavilland (Airco) DH-4 (oz352) was originally designed to represent a United States Mail aircraft of post-WW1, however I’ve rendered it back to its original wartime configuration [main pic, 003-006]. I was inspired by the color scheme of N6416 “Sultan Selim II” of RAF 220 Squadron operating out of Imbros in the Aegean Theater of operations, 1918. The name and scheme were something of a tongue-in-cheek challenge to the Ottoman Turks, as Selim II, son of Suleiman the Magnificent was said to have been driven mad by pleasures of his harem. Of course none of that was historical fact, but it still served as a wonderful if not dangerous (had the crew gone down behind the lines) goading by its British crewmen.
The DH-4 was a very stable aircraft with one critical point, that being the large gap between the pilot and the gunner…a gap the was occupied by a fuel tank. Obviously crew communications was difficult and if that tank caught fire, the gunner/observer had no chance at survival. The gap was removed in the successor DH-9, an aircraft that unfortunately did not have the flight qualities of its predecessor, and so the DH-4 soldiered on to the war’s end.
The model’s scheme is the product of computer graphics and printing. Isn’t technology wonderful…usually. Thanks, Steve and Mary!

Neal, Thank you for the magnificent build. I cannot seem to see the size of the dihedral on the plan. May I ask what angle or height at the wingtips did you use.
Thank you, Lewis

Maybe compare this with the 27 inch Guillows plan at De Havilland DH-4 (oz4174) that one shows 1/2 inch under each wingtip (labelled as scale dihedral) but then has a note saying to increase wing dihedral for better flying stability, so both wings 1-1/4 inch under each tip.

Notes

* 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.

Scaling

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.
