About this Plan

Folland Gnat T1 (Hawker Siddeley Gnat T1). Radio control PSS model, for slope gliding.

Quote: "Build from our full-size plans! Folland Gnat T1 Power Scale Soarer by Alan Hulme.

A few years back, I built a Red Arrows Hawk PSS model designed by my friend Andy Conway of Edinburgh. It was controlled by strip ailerons and all moving tailplane, had a span of 46 in and weighed 2-1/2 lbs. It flew superbly. Since then I have designed and built a number of PSS models including a Venom, Mustang, Nimrod, Fulmar, Kawasaki Tony, FW152H and a Corsair but always had a yen to try a Gnat.

Plans for this model were completed late 1993, and the model has since flown at PS5 meetings during 1994. Controls are similar to those used on the Hawk. The model is roughly 1/8 scale, spans 39" and has an all up weight of 11/2 lbs.

Making a start: Building starts by cutting out the 3/16 balsa sides, attaching the 3/4 and 1/2 in triangular strips to the inside edges and then, using Bostik Contact Adhesive the 1/32 ply doublers.

Formers F1, F2, F4 and F5 are next added and the white polystyrene foam blocks are stuck to the balsa external sides between the two formers F2A and F4C. PVA white glue is suitable for this. When the adhesive has dried, the blocks are lightly sanded to the former contours and are then covered with 1/16 soft sheet balsa using Copydex. Now add the soft sheet balsa to the underside of the fuselage and in front of the cockpit.

The Micromold N63 bellcrank and 10 swg piano wire shaft are now fitted between the 1/8 ply rear fuselage bearers, the pushrod is connected to the bellcrank and the former F4B is located. The 1/2 in soft sheet balsa and 1/4 x 1 in soft balsa strips are now added to the top rear part of the fuselage. Now cut a 3/16 wide slot through the 2 balsa pieces to locate the fin.

Sand the fuselage to shape. I recommend builders purchase the 1/72 Matchbox plastic kit of the Gnat and after assembling the plastic fuselage with Sellotape, use it as a guide to assist in obtaining the correct fuselage shape of the model.

The wing: The wing cores are now cut from white polystyrene foam using the two template outlines on the plan. Note these show a lead in piece at both leading and trailing edges to assist in aligning the cutting wire.

The soft balsa leading and trailing edges are now added to the wing cores. I recommend that the leading edge balsa strip be cut to allow 1/8 in oversize above and below the core surface, The trailing edge strip is fitted to be flush with the top and bottom core surace. This will enable you to butt the soft 1/16 balsa sheeting to the protruding leading edge strip when skinning the wing. I use Copydex adhesive thinned down as a skinning adhesive..."

Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

    ScaleType: This (oz14883) 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.

    ScaleType is formed from the last part of the Wikipedia page address, which here is
    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.

Had to correct original article notes. First RAF display team to use them was the YellowJACKS.

* 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.
