About this Plan

Shark. Radio control pylon racer. Joe Foster's Formula One Pylon Racer. Wing area 452 sq in. K&B 40 shown.

Quote: "BY ROBERT MORSE and JOE FOSTER. If speed's your bag, good looks plus flyability, then Foster's Shark is for you! Why, you ask? Answer is simple, for this pretty bird really moves. The Shark.

We are presenting here a wood construction version of the new Francis Products' fiberglass racer kit which is based on Harvey Mace's 1969 Reno racing beauty. Mr Mace is quite frank in stating that the Shark was designed primarily with appearance in mind which explains to a great extent the beautiful lines of the model.

Joe Foster, the 1967 NMPRA champion chose the Reno racing Shark because of the many compound curves which would lend strength and rigidity to fiberglass construction. Joe was held back for some time because of the apparent difficulty in construction of an elliptical wing. Joe solved this problem by using the flat back airfoil. This type of wing construction has proven not only a simple, fast, and accurate method of building a wing, it has proven itself in the air.

Joe's first three timed flights on the Pioneer R/C Club's Pylon course resulted in one heat at 1:39.5 and two heats at 1:37.5, taken simultaneously on two stop watches. Posting times like this in his first three heats tend to point out that Joe has come up with an excellent aerodynamic arrangement.

In the version presented here, we have changed nothing but the method of fabricating the fuselage. Due to the compound curves in the fuselage we've chosen the comparatively simple method of quarter paneling instead of the laborious planking method. If you'd like to fly a Shark, choose either method you like, fiberglass or wood - they both build quickly and fly fast.

FUSELAGE ASSEMBLY: Begin the fuselage by cutting out all parts (3/16 sheet sides, 1/32 ply side doublers, 1/4 sheet balsa forward doublers, and so on). Complete the fuselage side assemblies by contact-cementing the ply doublers to the 3/16 sides and fiber-glassing the engine mount retaining nut plate on the aft side of the firewall.

With all components cut out and sub-assemblies completed, build up a simple assembly jig like that shown in the phototographs. We cut the jig formers from 1/8 cabinet grade ply to the width shown on the plan view and then cemented them to the building board. The entire jig construction took only 30 minutes of our time, and paid us back handsomely with a true fuselage.

Assembly of the fuselage begins by placing the side assemblies in the jig and then cementing the formers in place. Install the 1/4 in doublers in the fuel tank area, being sure to butt them solidly against the firewall.

It's time now to try the fuel tank on for size; if it fits well, slides in and out easily, proceed with the top planking.

Cut the quarter panel sheets roughly to size, then sand the lower level to fit the top edge of the side assemblies. Keep sanding until a nice fit is obtained - it won't take long! Once the quarter panels are in place, add the top sheet forward and the inside blocks in the nose section and finally add the cockpit turtle deck structure. Pull the fuselage from the jig..."

* 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.
