About this Plan

DH.88 Comet. Radio control scale twin, for electric power with 2 x Speed 400 motors.

Quote: "DH 88 Comet. The original full-scale de Havilland D.H. 88 Comet first flew in 1934. The Comet was designed and built to compete in an air race from London, England, to Melbourne, Australia: the 'MacRobertson' race. The prize money for this race was about $100,000. The race was run over a distance of 12,300+ miles. Charles Scott and Tom Campbell Black's red-and-white 'Grosvenor House' Comet (one of three Comets entered) won the race. A KLM Douglas DC-2 came in second, with another Comet finishing third. (Incidentally, the first stop after leaving London was Baghdad!)

The D.H. 88 was a beautiful aircraft that has motivated many modelers to build replicas. I was motivated to build my Comet by Mark Rittinger's article about his Sportwin design, which was published in the July 2001 issue of S&E Modeler. The Sportwin inspired me to have another go at this new Comet. My electric-pow-ered scale model is not quite to scale out-line; if it had been built to scale, it would have wingtips just 2 in. in chord. To "tame" the airplane, I increased the wingtip chord to 3 in. and added 2 in. to the moment arm — the distance between the wing and the tail. This is my second attempt at building a model of this aircraft. The first model was heavy and tip stalled very eas-ily, as did the full-size Comet.

Lightweight construction and strength are now my aim when building any model. Even so, the wing loading of this new model is quite high at 21 oz/sq ft. Consequently, I have only launched my Comet with the aid of a pedal launcher (described in the September 1999 issue of S&E Modeler). A strong arm and a straight throw might also get the airplane up to flying speed, though.

Wing Construction. I used cyanoacrylate (CA) glue for all of the model's balsa-to-balsa joints, and carpenter's aliphatic glue for the joints between plywood parts.

The wing's construction started with the assembly of sheets of 1/32-in medium-grade balsa wood to form the one-piece upper and lower wing skin surfaces that extend tip to tip.

After you have the wing skins made, mark out the locations of the spars and ribs on the lower skin. I recommend using carbon paper to transfer these spar and rib lines to the balsa..."

    ScaleType: This (oz10229) 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.

    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/De_Havilland_DH.88_Comet
    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.
    Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

* 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.
