New wings for the Skytrex Gotha

Rate this Entry
[QUOTE=tonyc206;48086]When I replicated the metal wings for my bombers in plastic I noticed that the Skytrex Gotha wings are not accurate. The upper wing shape is wrong. The rake angle is too great and it should not continue to the centre to form a point as it does (at least not on the drawings I have). The two wings do not match each other in shape as they should and the strut locations are not quite correct. The lower wing is slightly short and also has no Ailerons marked on it.

So I've decide to try to make my own from plasticard. As I have at least a further 3 Gothas to make, these will hopefully be 'masters' from which I can then cast wings for each model from plastic as before. Also if I am successful I will be able to supply copies of my new plastic wings to anyone who might want them (at a small cost of course).

So the first thing I did was to accurately scale a set of drawings and stick them onto a sheet of 1.5mm Plasticard:

The cut out drawings were stuck on using 'Copydex' which is a rubberoid type adhesive. This is important as any water based adhesive would soak into the paper and may cause it to stretch or tear. I pasted the adhesive onto the plasticard and used an old brush to make sure it was in a thin even film before placing the paper on and smoothing it very gently. Then I left it to dry for about an hour.

Here's a shot of the Skytrex wings on top of the drawings so you can see the difference..

The rake angle of the top wing is quite a substantial difference and you can just about see how much shorter the lower wing is as the faint inner line can just be seen.

Next thing was to crudely cut the new wings from the plasticard....

This is thick plasticard and requires patience to cut it without damage or mistake. I always make sure that I take time to score it lightly first and then about 3-4 times more, increasing the cut pressure gradually each time.

Then the new wings were carefully trimmed around the templates using the scoring method and a razor saw to get into those corners.

Shown here again with the Skytrex wings to show the difference.

Next I scored the ailerons before removing the templates. Then repeated the aileron scoring on the underside.

This left me with two very flat wings with markings scored on them. So then comes the shaping.

This final photo (for now) shows the difference between the basic cut-out upper wing and the now shaped lower wing..

Still lots more work to do yet and I’ll keep taking Photo’s and post updates on here[/QUOTE]
