About this Plan

Ariel. Rubber powered sports model, mid-wing semi-scale. Aeromodeller Sept 1948.

Quote: "The Ariel was one of two rather similar mid-wing monoplanes built during 1935 and early 1936 as a freelance design for a fast single-seater light plane of that period. Ariel was the second of these two models and after more than twelve years of active flying is still going strong. The model was completely stripped and re-covered for the first time last year after a collision with a car, but apart from new tissue and a section of the mainplane the model is flying with all the original components intact including the airscrew.

Fuselage Construction. First cut out the fuselage sides from medium weight 1/16 sheet balsa, sandpaper smooth and mark the position of all cross struts and the holes for the front and rear wire wing fittings, mark the hole positions very carefully so that they are exactly the same on both fuselage sides, otherwise there will be a difference of incidence of the left and right wing when the model is assembled.

In order to have a rigid framework when building the fuselage, cut temporary bulkheads from 1/8 sheet balsa. One the exact depth of the fuselage sides at the third cross strut from the nose and the exact width between the fuselage sides at this point and a similar bulkhead for the sixth cross strut position. Pin these bulkheads in position between the fuselage sides.

Next fit the tail block and No.1 bulkhead at the nose. When these four pieces are fitted in position the fuselage sides will take a natural curve from nose to tail and the remaining cross struts and formers can be cemented in place. Note that 1/8 by 1/16 cross struts are fitted at all the former positions and the formers cemented on top of them, finally these cross struts are partly cut away to give clearance for the rubber motor.

The engine cowling and fuselage deck fairing from the nose to the rear of the cockpit is cut from one piece of stiff cartridge paper and the undercarriage leg fairings are made from the same material

The undercarriage is shaped from one piece of 18 gauge steel wire and is held in position by two pieces of celluloid tubing cemented between two fuselage cross struts, the rubber band shock absorbers are hooked in place with a piece of wire through the open cockpit. Before covering the fuselage sides cement celluloid washers at the points where the wire wing fittings pass through the fuselage.

The nose block is shaped from 1 in block balsa and is located by two pieces of celluloid tube reinforced with wire cemented into the rear of the block. These projecting tubes fit tightly into corresponding holes in the ply and balsa front bulkhead of the fuselage..."

* 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.
