Dewoitine D-510. Scale model French fighter for control line.
Quote: "This sleek Dewoitine D-510 experienced great success in the French Air Force during the early thirties. Its Armament and speed were superior to the conternporary Boeing P-26A. With a 20mm cannon and two wing-mounted machine guns, the D-510 had a maximum speed of 250 mph. Its 500 hp Hispano-Suisa 12 cylinder engine took this ship to an altitude of 9,840 feet in three minutes 36 seconds. The P-26A, armed with only two machine guns had a top of 221 mph.
The D-510 was widely exported. Unfortunately for France, it wasn't to be long before Germany's powerful Focke Wulf 190's would shoot them out of the skies. While the D-510's saw active service with the French Air Force during 1939-40, their effectiveness had long since passed by then.
Begin fuselage construction by cutting two 1/16 sheet balsa sides. Mark bulkhead locations. Glue 1/2 x 1/2 in hardwood motor mounts to each side; taper mounts slightly near nose (see top view). Glue in bulkhead F-10, proceed toward front with other formers. Rubber bands insure slight fuselage roundness. Build in the Perfect No.8 gas tank when installing 1/8 in plywood bulkheads F-1 and F-2.
Install 2 in bellcrank and push rod after inserting 3/16 plywood mount. Drill motor-mount holes, secure nuts to hard-wood (solder to imbedded tin plate). Install pre-sanded x 1/2 in balsa block on motor mount top. Bind 1/16 in landing gear wire to F-1 with soft wire...
Model should balance just forward of main wing spar. A .15 engine should be the maximum power for this model. I used an 8-4 prop and fifty foot lines. Due to its long tail moment this D-150 is unusually stable for a scale job. If you employ an engine smaller than a .15 shorten your lines. Flown off grass or concrete, your Dewoitine will provide many happy hours of flying enjoyment."
Hi Steve - Here is Donald E. Mowrer's Dewoitine D-510 from American Modeler magazine issue 10-62.

Did we get something wrong with this plan? That happens sometimes. Help us make a correction
* 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.
