Douglas Skyrocket (oz370)
About this Plan
D-558-2 Douglas Skyrocket - Jetex powered scale model, from December 1948 Flying Models.
Quote: "DOUGLAS SKYROCKET by Joseph H. Wherry Build this triple-threat model of the swept-wing D-558-2 as solid scale, or jet or whip-powered flying scale.
Here's a CO2 capsule-powered flying scale model of the US Navy's Douglas D-558-2 sonic research plane. It flies on 20 ft nylon lines ; it also will perform admirably as a whip job. In either case a variety of control systems will work - ours may be seen in the photograph above and in the accompanying plans.
If you're a solid scale addict, you can construct a neat model by building the Skyrocket from solid blocks, directly from our published plans. Close attention to airfoils, fuselage cross-sections, wing droop, landing gear details, and the nose device will result in an exhibition model that will catch the eye of your fussiest modelling friend. A solid model built from our plans will be to the scale of 1/4 in = 1 foot. For a flying-scale job, the plans herewith should be enlarged to twice the size shown. This will give you a ship to the scale of 1/2in = 1foot.
Building the fusealege: Cut two of each bulkhead-half, as indicated on the plans. Notch all bulkheads to receive top, bottom and side keel pieces, which are 3/32 x 3/16 balsa. All other stringers are 1/16 x 1/8 hard balsa. Build directly over the enlarged plans, pinning the top and bottom keel pieces in place first. Bulkheads cemented in place will result in a partially finished left half of the fuselage. Let dry, then remove from your workboard and cement the opposite bulkhead halves in place.
Next, place the stringers in position, cementing opposite (side) stringers, to prevent warpage. Not shown on the plans is the reinforcement of the top stringer between bulkheads 5 and 6, needed to carry the conduits which handle the control lines. This is accomplished merely by cement- ing extra sheet balsa to each side of the top stringer. Cut away the stringers on the top of the fuselage between bulkheads 2 and 3 and cover the space with clear plastic, as shown..."

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

* 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.
