Curtiss Owl (oz7459)
About this Plan
Curtiss Owl. Free flight scale model by J Bridgewood. From Model Aircraft August 1953.
Quote: "This is the writer’s second model of a US. Army observation monoplane, and it was originally designed around the ED Bee. The scale is one inch to a foot and the completed model weigh 14 ozs. After only two hand-launch tests, it 'flew straight off the drawing board' requiring only a small amount of weight on the tail. After sixteen flights the writer decided to install a Mills 0.75 and remove the tail weight.
This still gives ample power, and forty-six flights have been made to date. The first of seven flights made during the Daily Dispatch Rally gained second place in the EJ Riding Memorial Trophy scale event.
Commence by carving the fin and tailplane from 3/8 in sheet as these are fixed permanently before completing the fuselage planking. There are two reasons for the sheet fin and tailplane - to give the true scale metal covered finish, and also to put a little extra weight at the tail, which all high wing monoplanes seem to require.
Fuselage. After building the crutch, fill in between F-3 and F-4 with 1/8 sheet, then cement engine bearers in position. and add the bottom half formers F-3 to F-9. Make certain that the crutch is securely pinned down before the 1/4 X 1/8 strip is attached. Fix two planking strips, one on either side, to ensure the lower half of fuselage is kept true when it is lifted from the plan.
Now add F-1 and top half formers F-2, F-3A, F-7A, F-8A and F-9A, and 1/4 x 1/8 strip from F-7A to F-9A, also cement in position F-4A, F-5A and F-6A adding 1/8 square strips which run from top of F-3 to F-7. Note that this strip does not run straight, but requires cracking between 5A and 6A..."

* 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.
