Leyton House CG901B

On to the next one, finally after 2 a 2 year absence this will be a Formula 1 car . The Leyton House CG901 is from the 1990 season, incidentally the first one designed by the now mythical Adrian Newey (whose cars won championships for Williams, McLaren and now Red Bull). An eye catcher due to both its innovative design as well as being the one car which challenged, albeit briefly, the McLaren MP4/5B with whch Ayrton Senna won that year's title.

On for the build now, kit is Tamiya 1:20 scale, and I am aiming to detail as much as possible. Work began during the last Expo, where after some test fits the monocoque chassis (i.e. front) was joined and corrected, frame for the top open part was scratch built, and the side radiator housings were separated from the molded electronics boxes (thanks to Hubert here )













The front end has now been completed, and a dry fit test was effected. Improvements here are scratch building of the bulkhead, separating the upper and lower front suspension arms (so that they can fit within the new scenario), scratchbuilding of 3 hyraulic pumps from steel tube and hydraulic reservoirs from plastic rod, fitting of the steering system and the overlying frame to hold 2 hydraulic reservoirs, plus 2 brackets which will hold the steering rod housing to the bulk head. Obviously the necessary wiring/brake lines will be added after fitting. The 'hole' in front of the cockpit is to house the coil overs which still need to be scratch built.











Now on to the paint and finish shop, where I can't wait to put on the colour and start part of the heavy carbon fibering involved.

looks nice..

Nice job Alana

another interesting kit here Alan.

Wish it was Ray!, however yes the first image may somewhat give that impression, so I changed the image to the kit box art. Thanks for your observation bro!

Alan, it was not doing any harm my observation was purely to pull your leg

Don't worry my dear friend Ray, afterwards I realized that I had not taken a shot of the box art as I had already tucked away the camera!

looking nice Alan

More chopping and modification work done prior to hitting the paint shop.

Exhausts: the tip was modified to resemble real life, and test fitted with the engine. Undertray exhaust outlets were also modified to take the new exhaust:

Injector tray and air intake trumpets also modified, where the plastic molded trumpets were removed and replaced with aluminium ones, and the injector tray modified to take the new trumpets.

After removing the molded trumpet a hole was made and the trumpet inserted. The same was done for the injection undertray.









Rear coil overs modified to take a new spring rather than having to do with the kit molded one. the anti roll bar was also replaced.

Very nice work ..welldone..

More progress: paint was laid, with materials used being: Pure brilliant white and Leyton House Aquamarine Blue both by Zero Paints, and green by Mr Hobby (decanted and shot through the airbrush). Please note that the colors are base coat colors and need clear coating.

Monocoque still requires carbon fibering.

Tyres: yess, this time the logo is sprayed not decalled. When the car will be completed then the side(L, R) and revolving indicators will be added. The tyres were sanded beforehand, removing the sheen and mould mark from the contact surface.

Exhausts: here the process was a bit long, but have to say one of my favourites. The fabulous Alclad hot metal series was used here. This time the exhausts have a slight golden sheen on them, yet if one were to shoot the hot metal blue over yellow
green wold result. Thus after applying polished aluminium over semi gloss black, MOTIP paint decanted and shot through the airbrush, a light transparent yellow was applied, followed again by another light sealing polished aluminium. This way the yellow and blue are separated and no interaction should occur.

Transparent yellow over polished alu.

Following the second polished coating hot metal violet stain was applied.

Hot metal blue, light coat as this is a very strong color, is applied. Here although a greenish hue appears this is due to light reflection and not paint interaction.

This was then followed by a mist coat of hot metal red, then an overall dust coat of transparent smoke.

A very happy with the result, as the polished alu base is still highly visible yet all colors therafter applied still bounce through, especially with light reflections. All that now remains is a light wash, especially where the pipes are wed into one, yet am undecided as to whether to use black or sepia - both Vallejo washes. Any opinions are more than welcome.

The other parts have all been colored, mostly semi gloss black.

Next stage: carbon fibering and overall clear coating, to be followed by decals and the sealing clear coat.

Prosit eh... very good process....

Meticulous progress Alan

nice Alan keep it up

Finally, after a short break due to work, a rough patch in life and now heat  , I hope to be able to build a rhythm to say work to a finish.  to date I have carbon fibered all the required areas, decalled and clear coated.  Now I am polishing following which the model will be put together.  The pics are just a teaser of part of the work completed, with more progress earmarked for the week-end.

The monocoque chassis polished - still a little bit to do but:

Hope to keep the updates coming now:D

good progress so far!

Lovely work Alan, your patience sure pays off. The exhaust is great and so are the tyres, nothing like a good paintjob, once you try that out you will not go back to decals. Dying to see this finished, looking really nice.
