Sopwith Pup Instrument Panel and Le Rhone WW1 Engine (dummy Engine for 1/3 Scale Sopwith Pup)




I used the 3D printer to make the instrument dials and the compass.
I also made the fully functional control stick

I have also made the  a dummy engine for my 1/3 scale Sopwith pup.

I made the cylinders separately and the engine is nearly finished.

I still have to fit the induction tubes

The instruments are made by:

1) Drawing the bezel and printing it on a 3D printer.
2) Printing on paper using a laser printer the dial which is drawn in coredraw.
3) The needle is made from white plastic and is connected to a piece of wire that goes through a hole in the dial face.
      This hole in the dial face has a small eyelet glued to it , the wire goes through this eyelet and is bent down on the other side to  form a pendulum,  this can have a blob of solder added to it to increase the weight.
4) The face of the gauge is made from perspex.

The needle can have their pendulums at different angles so the gauges all read correctly and move when the instrument panel moves.

    Did you ever make the .stl files available?

    I cannot believe I have never see this before on Instructables. Took a contest for me to notice this. it's truly awesome

    Hi Thanks for the interest,

    All parts are drawn to full scale and then printed to the size required.

    Full article on this flying model can be found in the Australian Airbourne Magazine.

    Information is also available at

    The ABS plastic is very strong if glued with the correct glue.

    I have mounted two 200watt speaker on the dummy engine for the Vickers gun sound.

    WW1 flying models always need a lot of nose weight due to the ratios of the front of the aircraft and the back of the aircraft with respect to the centre of gravity.

    Thanks for the interest.

    The aircraft has come a long long way since I posted on this site

    The plastic is ABS and when glued with the correct solvent it is very strong.

    I drew the engine in a 3D package so that I can print it in any scale.

    I have aircraft in 1/6 1/4 and 1/3 scale.

    My build forum is this has much much more detail regarding all the aircraft I have built and also the techniques used.

    I fly at the National Aeromodelling and Aviators club in Australia

    Wow! Very nicely done. Looks like scale masters work to me.

    Are you reinforcing the back of the engine or do you think the plastic will hold up to the vibration? Also where did you find the drawing for the engine or did you draw it yourself?
