About this Plan

Skua. Control line stunt model.

Quote: "Looking for a realistic stunter to suit the latest .19 and 3.5 cc engines? Skua, by Dave Christopher.

TEN YEARS AGO rival camps in control-line development in this country were centred upon Weston-super-Mare and West Essex. In the intervening years, interest has swayed from the original enthusiasm for control-line stunt in these quarters, but we are happy to report that 1960 has seen a big revival in the Somerset community, particularly in the field of combat and precision aerobatics.

At the British Nationals, Dave Christopher from Weston made a considerable impact through his most attractive Skua design, entered for the Gold Trophy. Jet-like lines coupled with a mottle camouflage finish made his model one of the most attractive on the field and but for Dave's (as yet) limited experience among the expert acrobatic flyers, the model might well have placed very high. Originally created for the American .19 size engine, it is also suited well to the 3.5 cc motors, particularly the new Rivers Silver Arrow which is detailed on the plan.

Construction: Skua closely follows the current trend of design for precision aerobatics with coupled flaps and elevator and fairly long nose for smoothness of manoeuvre. It also offers an intermediate size between 2.5 cc and the larger 5 cc. types.

Fuselage construction is commenced by cutting engine bearers to length, and making up the 10 swg undercarriage which is bolted to the 1/8 ply former F4. Similarly, F1 and the tailwheel brace are cut from 1/8 ply, and pre-cemented as well as checked for engine bearer spacing. Fuselage sides are cut from 1/8 medium sheet with 1 mm ply doublers cemented on to the inside faces, then bearers added. Join sides with F1, F4, F9 and F10 (lower sections) with tailwheel brace added, and F11. Note, rear end of fuselage is left open for jet pipe effect. After fitting the tank, with its centre line on the same level as the needle valve, put the fuselage to one side and build the tailplane.

This is a simple structure using 1/4 in strip of different widths for most parts. Elevators are built separately, and a 14 swg wire connecting piece, with control horn soldered centrally, links them. Nylon hinges are preferable. Completed tailplane can be cemented to fuselage but first see notes on plan concerning the removal and later replacement of the fuselage sides in this area. Add the 1/8 x 3/8 longerons, F7 and F8.

Wing construction is started by cutting one 3/32 wing spar and pinning vertically over one of the wing plans. Make ten ribs from 1/16 sheet by the sandwich method detailed on the plan, and cement and press them into place on the spar..."

* 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.
