Quote: "A Control-line model of a dirigible-borne single-place fighter. Curtiss F9C Sparrowhawk, by Capt David H Brazelton.
For those who like historical aircraft, here is a model of a little airplane that performed great deeds. It is a shame that its exploits are so little remembered because they were the basis of many present-day experiments in launching and retrieving aircraft from an airborne platform. The 'Sparrowhawk' was standard equipment of both the dirigible 'Macon' and 'Akron.' This model is patterned after the aircraft carried aboard the Macon. The Akron model differed in coloration and included full wheel-pants and aircraft-carrier hook. Both aircraft were each armed with one .30 calibre Browning machine gun.
So, if you have an .09 setting around and want to build a model that looks good on the shelf, and in the air, get your knife and some balsa and let's go!
TAIL: Elevator and rudder are cut from 1/8 balsa and sanded to streamline shape. Cut the rudder loose from the vertical stabilizer along the heavy line and cement them back together with the rudder offset to the right, as shown in top view. Bend the 1/16 music wire elevator interconnect-wire to shape and solder the control horn as shown. Cut the elevators loose and slit the leading edge to insert the interconnect-wire flush. Cement the interconnect wire in place and cover the leading edge with silk.
Hinge the elevator to the stabilizer using your favorite hinging method. We prefer alternating cloth strips. Bend a 1/16 wire pushrod, about 6 in long, to fit through the horn and hold it in place with a small washer and solder. Sweat a 1 in piece of 1/16 id brass tubing half way on to the end of the pushrod, so that you have about 1/2 in of tube to accept the other end of the pushrod.
WINGS: Lay out the leading and trailing edge and wing tips of the upper wing. When the cement has dried, crack the leading and trailing edge just outboard of the 5th rib from the tip. Lay the 1/8 x 1/4 in main spar in place and prop up the tip so that it comes flush with the top surface of the spar. Place the 1/8 square rear spar in place and crack it at the same place as the leading trailing edge, so that the outboard edge can be kept flush with the bottom surface of the edges. Cement the 1/32 x 1/4 strip to the trailing edge of the rear spar 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.

ScaleType: This (oz1565) 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/Curtiss_F9C_Sparrowhawk
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.
