Before the T/S sets became available for these models, I’d bought some Formula Perfect stuff, including the turned trumpets and resin tray. There was also an extensive pre-cut p/e set:
There’s one slight bubble in the resin tray that needs addressing, then it’ll be ready for some satin black and the first of the carbon decals.

Hmmm. I temporarily assembled the FP trumpets in their tray, but they dont look right to me. The spacing is too much, and there is no radius on the edges:
Here's the real thing:
And the TS version, which I think is slightly better:
Although ironically, the original kit items are probably the closest in terms of spacing, but they're obviously plasticky and lack the surface realism of turned parts:
Net result - I've ordered the TS versions. For less than £20, didn't seem worth the compromise.

With the inlets on hold, I continued with building up some other stuff:
The jack plates and a.r.b. Brackets are made up of laminated p/e, to simulate cnc’d plate. There’s also a base plate for the oil catch tank. There was a lot of residue from the plastic backing on these parts, easily removed with enamel thinners:
Considered soldering, but in the end went for thin cyano, wicked into the corners with some fuse wire (sanded to make the glue cling to it better. I lightly sanded the mating faces for better wetting. I also applied cyano around the periphery of the parts and sanded it back, to eliminate the mating line:
Cleaned off any excess with a blade and fibreglass pencil, and ready for priming:
The a.r.b. links are turned brass, with two part rose joints on each end. I assembled these with Araldite:
All primed and ready for a dry assembly run:

Greetings!
How did you prime the metal parts ?

I use Tamiya Grey Fine Surface Primer aerosol can. The surfaces were lightly abraded with a fibreglass pencil first. For very small parts, I decant the aerosol paint into my airbrush. You can easily do this by attaching a drinking straw to the nozzle and spraying through that into the airbrush reservoir. You can apply a much thinner coat, with less wastage that way.

Thanks! So you do not use the "metal" primer ?

The Tamiya Fine Surface Primer has "for plastic and metal" written on the front of the can.

This is the rear a.r.b. Assembly. A lot of it is pinned together with brass rod you have to laboriously cut and file to length. To be correct you then have to glue a false fastener head on the end. Would have been easier to use nut studs, but there were go:
The brackets are fitted in the same way to the gearbox casing, but the holes are different sizes. I’ve made plastic spigots instead:
Ditto for the jack bracket:
It’ll all look much better when it’s properly painted.
