Chilton DW1 - free flight scale power model. Scale 1/8 model of the 1930s racer. From Nov 1949 Aeromodeller.
Quote: "THE Chilton D.W.1 is a small single seat racing monoplane of all wood construction and powered by a 32 hp Cordon Ford engine mounted in the upright position or a 44 hp Train 4t mounted inverted, the latter type is known as the DW2. The Chilton was designed in 1936 by two ex-D.H. technical school students who founded the Chilton Aircraft Co and put the machine into production at Hungerford.
Several of them are still on the Civil Aircraft Register: one, G-AFGH a Corden engined version is jointly owned by members of the Denham flying club. Cover shows this latter machine rounding a pylon, closely pursued by H K Hughes' Tiger Moth in the Grosvenor Challenge Trophy Race at Elmdon on August 1st last. The Chilton was piloted in the race by H. Bilborough of the Denham Aero Club.
About a fortnight previous to the race, A-FGH had sustained serious damage as the result of a forced landing near Watford, but with the assistance of the present owner of AESZ (now stationed at Thruxton, near Andover) who supplied various components needed for the repair work, the machine arrived at Elmdon on the day before the race was due to take place. A Train engined version, G-AESV, is owned by Squadron Leader Porteout. Reference to EJ Riding's Civil Aircraft No. 27 in the February, 1946 issue of the AEROMODELLER will provide information as to the colour schemes, registrations and history etc., of the full-sized machine.
The model is a replica of the prototype DW1 G-AESZ. It has a red fuselage, silver wings and tail unit, the registration is in red on the wings and silver on the fuselage. The number 29 is in black on the fin and was the machine's racing number in the 1937 Isle of Man race.
Rugged and simple construction is used throughout, the model can be taken apart into six separate pieces which are easily carried about or stored away. Two engines have been tried out in flight, the Clan .9 cc and the Amco .87 cc, the Amco gave the better performance since it is the lighter engine. However, almost any engine of under 1 cc that will swing the scale size propeller at over 5,000 rpm will be suitable.
The pilot shown in the photographs is a paper pressing made in the same way as is described for the under-carriage trousers. The finish on the model is Titanine cellulose dope sprayed on to clear doped rag tissue the letters being drawn on with a soft pencil and printed by hand.
Construction. All the main components, fuse-lage, wings, etc., are so simple to build that anyone who has built one or two duration models can tackle them with ease. The only parts likely to cause difficulty are the engine cowling and undercarriage trousers.
The top cowling is made of 26 gauge aluminium and is in two halves hinged together along the centre line. The 16 swg hinge pin is inserted at one end into the fuselage and at the other, forward end, into the nose of the 'power egg,' this makes it impossible for the cowling to come off unless the power egg is detached from the fuselage.
It is advisable to make a paper template before cutting out the aluminium panels, there is no double curvature so there is no beating to be done, the metal can be easily cut with scissors and trimmed with a file..."
Update 12/01/2015: Replaced this with a much cleaner plan (patterned background removed) thanks to TonyP.
Quote: "Hi Steve, Recently found your spectacular website. I found myself talking to a couple who are building a full size DW1, and being an aeroplane I have always liked I searched on-line for a plan and found your site. I am not sure if I am going to build one but as my second career was in computers (the first was aircraft) I thought it might help if I cleaned up the plan. Although building is not affected by the hatch lines printing certainly is, the extra ink used is considerable. The file is attached... Congratulations on a splendid effort."

* 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.
