About this Plan

PSS Komet. Radio control scale model for slope soaring. Wingspan 36 in.

Quote: "Go PSS with our pull-out ME 163 Komet, by Phil Morgan.

I was inspired to design this version after seeing the plan in Radio Modeller dated December 1985 for a 24 in span Komet for .15 engines. This model was designed by John Rutter and had a wing made from a flat sheet of 1/4 in balsa and used a rocking servo mount for elevon control. I decided to modify the model so that it would make a reasonably efficient glider. Recently in Silent Flight, were published a series of sections for use with swept back flying wings and this inspired me to build the model first seen at Moel Famau. To date I have sold about 10 of these Komets to people at our local hills by supplying a plan and a set of veneered cores, and so far 6 are flying.

The model is capable of tight loops without skewing out and will hold inverted for some time, also multiple rolls are very easy with the throws increased (10 consecutive rolls having been achieved). The modest loading of 13.25 oz/sq ft means that the Komet will fly in quite light winds as long as it is allowed to fly at its optimum speed which seems faster than other models.

Specification:
Radio: Standard size gear, using rocking servo for elevons
Span: 36 in
Section: EH 2/10
Weight: 1 lb 10 oz
Loading: 13.25 oz/sq ft

Building instructions: Cut out from 1/16 ply and 1/8 balsa a left and right hand side to arrows shown on plan, then laminate the ply and balsa using Copydex or similar. Carefully remove the cut-out shown for the root profile. (If ply is not available then glass the inside of the front section ahead of the wing and substitute the 1/8 balsa for 3/16 hard balsa).

Add triangular gussets where shown then fix in place formers 2 and 3. When dry. pull the fuselage at front and rear together and fix formers I and 4 in place.

Glue the wing panels together with the wing upside down on the building board so that dihedral is given by the tapering of wing only. (If desired a small amount of dihedral can be added to lose any impression of anhedral.)

Cut out holes for servos as shown then add We, false tie and soft balsa tip blocks, finally sand the wing to shape. Next, slide wing into fuselage, when central, tack glue in place. Fill any gaps between wing and fuselage with offcuts of balsa.

Make up torque rods from 12 swg piano wire or use commercially available ones. Slot the trailing edge stock so that ailerons are top hinged then glue trailing edge in place making sure that the wing profile is maintained.

Pass the torque rod ends through the fuselage sides and glue into the slots in the trailing edges. Epoxy bandage wing joint and also where wing meets fuselage. When dry add bottom decking and top front and rear decking and also the hard balsa nose block.

Tack glue two strips of 1/4 in balsa into hatch space then add two layers of 1/4 balsa on top. Remove assembly from fuselage then add a former at each end. This should give a hollow hatch which will give more room for the controls.

With the hatch tacked back in place, plane off top and sides of fuselage to give a rounded appearance. Cut a slot in top decking and fix 1/8 balsa fin in place. Add the keel using strips of 1/2 in balsa glued to the bottom of fuselage, cut to shape then cap with 1/16 ply to take landing knocks. Add wing leading edge and trailing edge fairings and blend in. Fit a clear canopy to the hatch, remove the canopy from behind the pilot and fit a bulkhead, then using light balsa, blend the canopy back to the end of the hatch..."

    ScaleType: This (oz14555) 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.


    Notes:
    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Messerschmitt_Me_163_Komet
    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.

Notes

* 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.

Scaling

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.
