About this Plan

Nucleus - Delta wing, class A or B team racer for 2.5-5cc engines. From Model Aircraft February 1957.

Quote: "Delta Wing Team Racer, for Class A or B. Nucleus, by WP Woodrow.

Nucleus is the development of four models, and though primarily designed for Class A racing, owing to its large wing area it can quite easily be converted into a Class B job by modification of engine mounting only. The Class A version with an ED Racer and 8 x 6 Stant prop has regularly clocked 75 mph, while the Class B version with an OK Hothead, has been timed at 95 mph. The model is very stable and easy to fly, and it is an ideal trainer for the newcomer to C/L flying.

Wing. Make up the rear undercarriage from 16 SWG wire and bind and cement to the ply mount. Cut out the centre section ribs, cutting the lead-out holes in the port rib only. Cement the under-carriage in place. Cut out formers W.1 to W.4 and cement into place, carefully checking that the assembly is square. Whilst the centre section is setting, make up the trailing edge and elevon from laminated sheet as shown on the plan, recessing both to take the silk or tape hinges. Fit the elevon horn, and when set, sand to shape.

Now cement to the front of the trailing edge the 3/4 x 1/8 in rib support and then cement the assembly to the centre section, again ensuring that the whole assembly is square. Cement the centre section and leading edge into place, also the tips. Do not forget the tip weight in the starboard tip. Make up the leading edges from 1/4 in sheet and add the rib supports, then cement into place. Add the two spars either side. Now cement into place the strip ribs, making them from hard balsa. If soft or medium is used, they will buckle as the wing covering shrinks.

Drill the port leading edge to take the lead-out wires and cement the brass tubes into place. Drill, and cement the bellcrank mounting platform of 1/8 ply between W.1 and W.2. Make up the control mechanism and fit into place, taking the extra precaution of soldering the two locknuts of the bellcrank pivot. Holding the elevon in the neutral position by bulldog clips at the tips, bend and fit the push rod to the horn, at the same time ensuring that the bellcrank is also in the neutral position. Check for freedom of movement and then bend the ends of the leadout wires to take the lines.

Now cover the centre section with 1/16 sheet and cut a slot in the underside for the push rod. Sand the leading edge to shape and also the tips. Do not yet fit the wheels to the rear under-carriage..."

Notes

* 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.

Scaling

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.
