About this Plan

Supermarine Spiteful. Radio control scale model fighter, for .40 power.

Direct submission to Outerzone.

Update 12/10/2021: Added article, thanks to RFJ.

Quote: "Pete Nicholson designed this model of the Spitfire's successor for .40 two strokes and five function radio. Model spans 52 inches.

All full size military aircraft usually start life as a ministry specification, so I decided I would draw up what I thought would be the ideal attributes for a scale model and look for a shape to fit them.

The specification was as follows:

WWII piston engined fighter.
Wide track retractable undercarriage.
Good looks.
Large wing area.

Above all, it had to be little-modelled and different. After all, with accurate flying scale models we can put into the air shapes that were rarely filmed or recorded and, within reason, get some idea of their flyng qualities.

It so happened the first 'Aeroplane Monthly' magazine I bought (way back in December 1977) contained an article on the Supermarine Spiteful. Looking at the photographs and reading the history of this machine, I decided that this was the shape, Aviation News (27 July - 9 August 1984) contained an excellent three-view, and now the stage was set.

I designed the smallest size model practical for taking retracts. It would be based around a .40 two-stroke and have the absolute minimum of surface detail. It must be highly practical - and operational most weekends!

With the exception of the finishing method the following construction notes are more a sequence than a stick-by-stick instruction feature. When read in conjunction with the drawing, construction should unfold as straightforward and fairly rapid.

Watch That Weight! A few pointers on weight prevention should help save those vital ounces.

Construction is a mixture of stressed skin, thick sheet and block. All block and thick sheet (3/16 and over) should be soft but firm and free from 'shakes'. Thinner sheet needs to be a light, rigid medium grade. For the wing skinning, avoid wood with soft patchy areas.

With a few exceptions, I use cyanoacrylate throughout. This in itself saves a few ounces since fillets of epoxy and PVA are heavier. To use the adhesive economically, make the joins using spots of cyanoacrylate every inch or so (similar to stitch welding). This is perfectly adequate when the structure is considered as a whole.

Accurate joints are required when working with cyanoacrylate, but this has another benefit as less filler is used to fill gaps at the finishing stage, which saves a few more ounces. The use of plywood and hardwood is kept to a minimum, it being used for the firewall and localised hard points only. Do not add weight by replacing the dihedral braces and other parts with these materials, as the structure is more than adequate without them ( the heavier they are, the harder they fall!).

Before beginning construction, plan the installation of all the servos, engine, tank, undercarriage, etc, drawing the details on the plan. This can then be transferred to the necessary parts and any holes or cut-outs made to accommodate them.

Wing Construction: The wing is built in four sections then joined before adding the skinning. Begin by preparing the wing sheeting, making oversize panels by joining sheets using PVA adhesive.

Pin down the lower spar and false trailing edge over its packing piece. Add the ribs, upper spar and leading edge followed by the Visin. vertical grain webbing. Remove the wheel bay portion of W3 and add the circular lining (formed around a suitable cylinder and left over length). Carefully sand to airfoil shape and add the upper 1/16in. sheet using impact adhesive.

Sand roots of panels flush and join outer panels to centre section panels. Add dihedral braces, servo bay linings, aileron bell crank details, block and gusset reinforcements, undercarriage, bearers and bay lining. Sand structure and add bottom sheeting, again using impact adhesive. Be careful at this stage not to 'lock-in' any warps.

Carve and sand leading edge to shape, add tips and do likewise. Mark out ailerons accurately and remove from wing using a razer saw. Add 1/4 in spars. Using the centre section dihedral brace, join the wing halves. Trim the roots at the fuselage area and add the wing dowel.

Fuselage: To the basic fuselage sides add the longerons, doublers and treblers. (Note that the port fuselage side is lengthened to allow for the engine sidethrust.) Using the plan view, erect the fuselage upside down over the plan. Add the 3/8 triangular firewall fillets, lower parts of formers F2, F6 and the 1/2 in balsa and 1/8. ply tailwheel formers with tailwheel.

Glue the 1/4 in bottom sheet to the formers and add the rear lower infill. Chamfer the lower fuselage side edges and bottom sheeting to match the formers and add the 1/4 in lower side sheeting. Square off the sheet with a razor-plane, but do not sand to final shape at this stage.

Lightly fibreglass the tank bay area and install throttle cable, elevator and tailwheel linkages. Add the upper parts of all the formers and the top 3/8 sheet. Shape sides and top to match the formers..."

    ScaleType: This (oz13368) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.

    If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.


    Notes:
    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Supermarine_Spiteful
    Wikipedia page addresses may well change over time.
    For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
    Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

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.
