About this Plan

Blackburn Shark. Free flight scale model biplane carrier-borne torpedo bomber.

Quote: "A Fine Flying Scale Model for .75 - 1 cc Engines. Blackburn Shark, by HG Moore.

THE Shark flew beautifully 'straight from the drawing board' after a few initial trimming adjustments. A 1/2 oz weight was put in the tail box to make the model balance slightly nose heavy at 50 per cent of chord on the top mainplane, and a small amount of down and right thrust was necessary to get a good flight pattern with a standard prop on the Mills .75.

Building Instructions. Fuselage. Mark out accurately on 1/8 in medium sheet the sides of the fuselage, also the lower mainplane dowel holes and former positions. Steam sides to shape, add all formers working front to rear. Bend the cabane parts to shape on the plan, making sure they are cut to correct incidence; bind them well to picees of 1/8 sq; cement and gusset in place across fuselage and add brass tube on top for upper mainplane runners, checking again for incidence.

Cut out 1/4 sheet to fit across bottom of fuselage to carry U/C pivot and lower centre-section dowels, cut V's so that dowels fit in and to allow 1/4 in sheet to fit flush with fuselage bottom; make up U/C pivot and bolt in place. Then cement block in place on fuselage, push lower dowels through and cement. Cut out 1/8 in ply motor mount, cement in place, cut out cowling as shown on plan, and attach to motor mount and fuselage front.

Make up lower C/S by cutting out 1/16 in hard sheet to plan and well cement in place on bottom of dowels and fuselage ; cement on to this the LE and 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.
