About this Plan
Skyhawk. Control line team racer. 18 span 1/2 A CL team racer. Aeromodeller December 1957.
Quote: "Jet lines provide a new look for Class A Team Racing and sport flying. Skyhawk, by Laurie Ellis.
Laurie Ellis enters the team race and sport flying field with this unusual design which has already hit the 85 mph mark in prototype form. Trike u/c, long fuselage and jet lines make it a real out-of-the-rut model, which will appeal to those who are looking for something quick to build with a robust crash-proof structure.
Anyone who has built a few powered models will have no difficulty with the construction and the model can be completed in about twenty hours of spare time.
The wing must be built first. Lay out the leading and trailing edge pieces flat on the table, and cement together. Cement to the wing tip fillets. Do not bevel the trailing edge before assembly. When dry, raise the wing outline from the board and slide small pieces of 3/8 in balsa underneath at regular intervals. This raises the svingframe enough to allow clearance of the wing ribs. Cement all ribs in place and cover entire surface with 1/16 in sheet.
The centre section is covered with the grain horizontal, the main body of the wing is covered with the grain running parallel with the leading edge. Note that the sheeting butts against the rear of the LE and the front of the TE When dry remove from plan. Make up bell-crank unit and fit to 1/8 in ply. Cement unit in place. Drill LE for brass tube line guides. Install lead out wires. Cover surface of wing with 1/16 in sheet. Cover centre section as well then cut out an elongated hole to allow access to bellcrank and installation of push rod.
The fin is made out of 1/16 in ply. Sand carefully, give two coats of sealer, then dope with two or three coats, sanding between each coat.
Make the tailplane from 1/8 in hard sheet. Sand to aerofoil shape. Install elevators with cloth hinges. Cement 18 SWG elevator link in place and secure with small pieces of gauze. Bolt elevator horn in place on under side of right elevator..."

* 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.
