RC Airplane Plans of the Hawker Demon

The above image of the RC Hawker Demon is interactive. You can use your mouse wheel to zoom in and out and if you press the shift key and the wheel you can rotate the image.

To return the image to the start point click on the house symbol in the top right hand corner.

The icons at the bottom of the screen have various effects but the "explode" icon is very spectacular!

The icon at the extreme right will give a full screen image.

All of this is available as I used Fusion 360 3D software to design this 1/5 scale Hawker Demon.

My Version of the Hawker Demon

The 3 photos below show 3 versions of the Demon, that is virtually the same as the plans depicted here. It was built many years ago and was originally a Hawker Hart bomber.

It was powered with an O.S. 120 4-stroke and I flew it for many years.(Photo #1)

I then modified it to a Demon fighter and changed the colour scheme. The power was now a Laser 150 4-stroke.(Photo#2)

The final version, as shown in the third photo, was also flown for many years and was well known all over southern Ontario and Florida.(Photo#3)

This is an easy flying and landing model that will not disappoint and should give you years of service as well!

Fuselage Details

The fuselage construction starts with making the fuselage sides from 3/16" thick balsa, as shown in photo #F1. Don't forget to make one side left hand and one side right hand! (Handed by the score and "crack" lines)

The fuselage top is made from 1/8"ply and 3/16" balsa. The top surface is flat.(Photo#F2)

Now we can start the basic fuselage box construction. Here you will see the advantage of interlocking construction.

Build the front part of the box first-the part that has no taper. This can be done "dry" with no glue. Tape can be used to hold things together and ensure everything is square. Use your precision square everywhere.

Only when you are completely satisfied with all, "wick" the CA into every joint.

The rear tapered end of the Hawker Demon fuselage can now be assembled.

Formers can be glued to the fuselage top, ensuring squareness again. Then the sides can be folded inwards and the fuselage bottom added. You should now have a perfect basic box that is straight and true. (See photos #F3&#F4)

Now the outer formers can be added, then the 1/8" dia. dowel stringers and the 1/8" balsa sheeting.

The gun troughs can be added as well as the other smaller details.(See photo #F5).

RC Hawker Demon: Fuselage Assembly.

The final fuselage will look like this. The cowl is made from balsa, but should be fiber glassed for durability. The Vickers machine gun and the Lewis gun are made from balsa and ply. The exhaust stacks use balsa dowel.

Power Options


The motor is an E-Flite Power 160.The batteries are 5S 5000Mah. They are retained by a velcro strap and can be changed quickly. 

Note that the upper hatch is retained by rare earth magnets.

Gas engine

The gas engine shown is the DLE 35RA. The muffler is concealed inside the cowl and makes for a neat installation.

Tail Section

Tail construction of the Hawker Demon uses the well proven 1/16" balsa core method. 

Ribs are added to both sides of the core and the whole assembly is bolted to the fuselage. This makes for a more scale appearance and means that replacement, if ever required, is really simple.

Robart hinge points are used and Dubro horns and hardware are suggested.

Please note that the 1/16" balsa covering is removed from the fin base, to show the internal details.

Upper Wing

The upper wing is constructed in three parts-

  1. The Center Section-See Image #UW1
  2. The Left Wing Panel-See Image #UW2
  3. The Right Wing Panel-See Image #UW3

An Aluminum tube aligns the 3 parts and the outer panels are bolted into position.

To start construction, the wing ribs (Typically as #UW$) are vertically slotted onto the Shear webs (#UW5& #UW6).

Note that all these parts have tabs on the bottom edges. Keep these in intimate contact with a flat building board. They will be removed when the initial construction is finished.

This image shows the arrangement using magnets and a steel surface on top of the building board. See here for more details of  magnetic building. 

Note that a full size plan is shown. This is the only time this is recommended in the building of this Hawker Demon. The upper wing has a sweepback of 5 degrees and thus to keep parts in the correct position this is a required process.

Now we take a look at the aileron construction. 

A 1/16" balsa core is used with ribs added top and bottom. 

Hinging uses 2 Dubro Heavy Duty Nylon Hinges and a wire at the root.

Return to Page Contents

Lower Wing

Construction is very similar to the upper wing, but is simplified by the omission of ailerons.

The above images show the three elements of the lower wing. 

Note that #LW1&#LW3 has the top sheeting removed to show the construction details.

Here we see how the upper and lower panels are assembled, for transportation, by using the special strut between the 2 panels.

It is held in place with long rubber bands.

The front landing wire must be unclipped from the fuselage but the remainder of the flying wired can stay intact.

PLANS of the R.C Hawker Demon

We are offering the plans as PDF files only. There is a total of 101 sheets.(236Mb) They can all be printed on 'A' size sheets. A few sheets need to be printed full size  and these are listed below. 

Because of the interlocking construction, the majority of the model can be built on a flat building board, referring to the printed sheets for information.

The sheets that do need to be full size are listed below. I visited a local Staples store that has a 36" wide printer. I found them most helpful and they happily adjusted the size of the prints to ensure they were exactly at a 1 to 1 scale.

  • X2020LC1to LC5- Only if you are cutting out the parts and not buying a set of laser cut parts.
  • E2020TWGA-2&-3  Note that top wing has 5 degrees of sweepback and the ribs are parallel with the fuselage, so a full size plan is required.
  • C2020LAG1&LAG2  These are the wire parts of the landing gear. (See this page for tips on wire bending)
  • X2020LC6&LC7  These are the markings for the ShuttleWorth Demon. Look here.

Below are 6 examples of the sheets in the package-

The price of the complete package of 101 sheets plus the 22 sheets of the BOM is $75.00USD.

Total package size is 236Mb and I will use a cloud storage service to send them.

To Order the PDF files, Just click on the PayPal link and I will promptly email the packages to you.

The Full Size Hawker Demon.

It is interesting to note that the Demon is part of the Hawker Hart family. The first Hart was a bomber and when it first flew in June 1928 it was faster than any fighter available to the RAF! 

As a result Hawker developed the Demon fighter from the Hart.

Take a look here for some beautiful  photographs of the Demon. This example is still flying and is part of the Shuttleworth Collection at Old Warden in the U.K. There is also a great video of the Demon flying!

The plans package includes PDF drawings of the fuselage and wing markings as well as the 3 different sizes of numbers.

They can be supplied by your favorite vinyl markings company , or cut from Monokote as I have done before. The Monokote method produces results a little thicker than vinyl, but it is a more cost effect!

The above 2 images are an example of the drawings in the plans package.

Scale Spinner

The unique scale shape of the spinner was a real challenge to produce economically. To machine one out of sold aluminum was a very expensive operation and hard to find a potential supplier.

The answer was to use the latest 3D printing technology -Selective Laser Sintering(SLS).

The material is a hard white nylon, that can be painted silver. As you can see, it has the cooling features that will help the electric version and will also aid in keeping a gas version cool.

If you would prefer a cone without the holes through it, please contact me and I can help you.

The register diameter worked out really well and the cone fits the backplate perfectly.

The supplier is Shapeways and the links below will take you straight to the purchasing page on their site.

There are 3 hatches on the Hawker Demon.

The cowl hatch gives access to the main power batteries.

The rear hatch offers access to the rear fuselage and also enables the large middle hatch to be removed and thus gives full fuselage access.

The 3D image below shows in greater detail how the full fuselage is completely accessible. all hatches are retained by strong magnets.
