Scale rivets

12 inch long strips. 50 rivets per strip.
24 strips = 1200 rivets.
Each rivet yields two heads = 2400 rivets.


Two rivet types; self adhesive & painted..
Painted rivets. Stick the self adhesive strip to the model.
Use a small brush to apply primer or paint to the holes
in the strip. Peel off the strip when paint has dried.
(Only 2 minutes with primer). Now ready for painting.

Stuck-on rivets.
Peel off the outer strip ( save this for painted rivets).
Apply adhesive tape over the dots on the paper,
rub down hard with knife handle and lift off.
Apply the tape to the model, rub down and remove the tape.
The adhesive dots are ready to be painted with the model.


The stuck-on rivets are slightly smaller than the painted
type and stand out more on the surface.
The painted type depend on how thick you apply the paint.
Practice on plastic sheet with both types, then paint
them to see if the result suits the model you are building.
Experiment to get the right effect.

.Scale paneling tapes
£3.50 pack. 120 x 9 inch strips.
Stick the tapes to the model, spray over with primer.
A light sanding then removethe tapes.
Leaves a very narrow groove to simulate panel
lines. Should be done before the rivets.

Sopwith Swallow by Fernando Blanco

My glow system for Laser twin. Each plug needs only 1.2 volts for easy starting!
On board two cell NMH 2000 mah. The throttle servo switch comes on at low throttle only.
The RUN switch is on for nornal start/ fly.
Three jack sockets are fitted.
1. Charge on board battery.
2. Test amps. with run switch off, this connects the on board battery and displays amps on a grond support box.
       Tells you the state of charge and that the plugs are both working.
3. Connects the 2 volt ground battery if the on board fails. Engine will start, then run without a battery.
    This saved me losing a flight at a World Champs.

flux 50p

Silver soldering tips.

1. No need to clean our rigging wire,. screws, bendy pipe, etc.
2. Use a brick as a base, rig the parts in position.
3. Mix a little flux with a few drops of water, not too much water.
4. Apply the flux carefully to the joint. The solder will flow on the
areas with flux, nowhere else, so wipe away any flux in
places it is not needed.
5. Lay pieces of solder on the joint. For circular parts, roll
solder into rings to fit.
6. Apply the blowlamp to the joint. If one part is thicker, keep the
flame on the thicker part, so that the thin part is not over heated.
7. The solder should flow with the parts just below red heat,
but it will still work if some parts do be come red hot.
8. Apply more solder from the stick if needed.
9. If fails to flow on any part, add more flux and try again.
10. If needed, allow to cool, clean the area and try again.
11. It is very possible to solder one side of a small part,
without melting the other side, even on a 6mm pipe for example.
So, you can tack it on one side, then bend it to close a gap
on the other side, and finish soldering the joint.

PRO-SKIN
PRO-SKIN is epoxy-glass sheet which has been moulded under high pressure and heat.
Result is a perfect flat sheet with semi-matt surface which accepts paint and glues well.
It is waterproof and fuelproof, and will not warp.
When a model has been covered in PRO-SKIN, it will be ready to paint!
Gone will be the weeks or months of tedious dusty work of rubbing down, messy resin/glass
covering, filling, more rubbing down and so on.
PRO-SKIN gives you a representation of a scale metal skin which would be hard to achieve
normally, and its instant!
When you add it all up, PRO-SKIN is not only MUCH quicker, it is also cheaper!
CHEAPER THAN PLYWOOD!
Please note that the thickness stated is nominal.
The process cannot control the thickness exactly and so this will vary.

We checked out plywood prices -
Proskin 0.3 mm thick £2.50 Sq Ft.
1/32"plywood (0.8 mm) £3 Sq Ft
1/48" plywood (0.6 mm) £5. Sq Ft
1/64" plywood (0.4 mm) £7. Sq Ft.
So, its
Cheaper and much Stronger than ply wood, and is ready to paint!

Use for Foam wings, instead of veneers.
Sheet is applied using Polyurathane adhesive. The adhesive has a foaming action which
fills the slight irregularities in the foam. Leading edges and wing tips are best made with balsa as normal.
Result is a hard surface ready to paint.
Wing is strong and stiff as it would have been with the normal veneer/glass/epoxy resin finish.

Built up wings instead of sheet balsa.
0.2, 0.3, PRO-SKIN is used according to the size of the model.
The wing structure is sanded until all ribs and spars are level, just as you would for sheeting with balsa.
The PRO-SKIN is cut with scissors slightly oversize.
(One piece covers the wing, no joining of sheets is needed).
Polyurathane adhesive is applied to the wing structure and the skin is smoothed down and clamped or weighted.

The adhesive foams up to fill any gaps and also give a filleting effect to make a strong bond with the structure.
The adhesive will be handleable in about 20 minutes, then the wing can be lifted and the operation repeated for
the other side. The PRO-SKIN will only work where there is no double curvature, so wing tips and leading
edges willbe made in the traditional way. The PRO-SKIN is now ready for painting!

Alternative adhesive is one hour epoxy with some filler to thicken it.
This allows more time to position the skins.
It is good practice to roughen the ProSkin suface at the glue joints.


Hunter wing with top skin fitted.   Hunter flap only 6 mm thick and completely rigid. Took 15 minutes to make.

Fuselages, small assemblies, ailerons etc, anywhere that a flat sheet will fit.
Perfect sharp and straight trailing edges are easy with PRO-SKIN.
Scale hinging for metal subjects now becomes easy! Hinges can be fitted with our
tiny screws directly under the thin, hard PRO-SKIN sheet. Hatches?
Just cut the hatch in PRO-SKIN, place it on the surface and mark around with a knife.
Cut out, and line the hole with narrow strip of PRO-SKIN glued inside.
Place the hatch into the perfectly fitted recess and secure with MRM tiny screws F.
Job done!
How?

Foam wings/tails/fuselage panels are covered in the thinnest PRO-SKIN, using polyu glue.
You must prepare the job well before applying the adhesive to one side of the foam,
spreading with a scraper. You must work quickly to get the PRO-SKIN in place within 5 minutes.
The PRO-SKIN is then held down with the foam wing outer block and weights, and left to set.
Adhesives.
Polyurathane sticks very well to most things (even your fingers).
It is very convenient to fit formers in glass fuselages because it needs no mixing.
Just squirt it from the bottle over the joint and it will form a natural, slightly flexible fillet.
Proskin will work with epoxy resins and cyanos, best to abraid the surface along the glue lines.
For an almost unbreakable trailing edge, just apply normal cyano so that it wicks between the wing skins.
It will set in a few minutes, then you will be able to knock the trailing edge of your wing on the edge
of your wooden bench. The bench will be dented, not the wing!
Limitations.
As you might expect, being a perfect flat board, PRO-SKIN cannot cover compound curves in one piece.
Most wing panels can be dealt with, and the leading edge is most easily achieved with balsa in the traditional way.
Double curvature wings may be possible by slitting the PRO-SKIN near the wing tip,
but you must experiment with this. Wings with a change in section, such as the Hunter or Javelin
will require a short slit at the front of the ProSkin
You can be sure that many new techniques will be developed with this new material when
ingenious modellers get their hands on it.
Polyurathane adhesive is very useful for all sorts of materials.
It needs no mixing, cures quickly and foams out to form filleted joints.

Building TIP
Shaping balsa Leading Edge.
1. Sand level with wing skins
2. Spray a little coloured paint on the front.
Sand with the paper at 45 degrees, so that the edges wiill not dig a groove.
One hand each side, pulling the paper around the leading edge
3. The paint will show exactly when the balsa reaches the finished shape.

NOTE. The colours look very dark on the screen, but are correct, see photos of my model.

For Spitfires
Use Dark Green and Dark Sea Grey for top. Medium Sea Grey for bottom.
Sky for band at the rear. Yellow for leading edge and roundel outer ring. Blue and white for roundels.
The red will serve for the roundels, but needs added yellow to be fully authentic.
These colours are matched to existing Spitfire MH434 at Duxford.

For Sopwiths use PC10 for top surfaces, Linen Solartex for the bottom.
These are matched to samples from RAF museum at Hendon.
Red, white, and blue for roundels.

One good system for painting a model is to use gloss for the main colours. This gives good
adhesion for any decals to be used. Finally a clear coat in Gloss, Satin, or Matt to give an even
finish and protection for the decals.
MR EPOXY is best sprayed on. Normal precautions should be taken.
You don't want to breath the vapours, or get the paint on your skin.
The paint will need to be thinned for spraying, 20% to 40%.
Normal cellulose thinners is OK, and different grades are available from motor factors.
