Your engine is completely inline with the rest of your Superb build.

Fantastic looking engine.  Good upgrade to the spark plugs.
Continuing to follow along.

Great work Mike, love that engine. Your PDF build log on the Tripe is proving to be a great help to me btw.

Hi all,
The kit illustration showing the rigging for the engine support 'Z' struts is wrong.
It shows correctly bracing rods fitted midway up the struts and routed across the fuselage between the front and rear struts of the two 'Z' struts.
What is not correct is that it shows a bracing rod fitted along the left and right sides of the 'Z' struts, spanning the front, centre and rear struts of each.
In reality all three bracing rods were fitted across the fuselage between the rear struts, centre struts and front struts.

I've pre-rigged both 'Z' struts, which will be finally rigged once fitted to the fuselage,

You certainly have an Eye for the details Mike! I envy that ability  8) The strut rigging looks outstanding as always!

Good knowledge Mike, mightily impressed by your fastidious attention to detail. Builds like this are a great form of online tutorial for me, enjoying following your work.  :)

Hi all,
The engines bottom support frame is complete.
The rigging is 0.12 mm diameter mono-filament, with 0.5 mm tube and 'Gaspatch' 1:48th scale Type C turnbuckles.
The three bracing cross bars are 0.4 mm diameter tube, with twelve end brackets from twelve plates (item 43) from (‘PART’ photo-etch for Fokker Dr.1 -S32-023).
The bars have an ‘RB Motion’ Aluminium Nuts Hex 0.79mm (1281-A) at each end.

The struts are reinforced with solid steel rods, so careful drilling through struts was required to avoid hitting them with the drill!!

On this particular aircraft, the wind driven pressure pump for the fuel system was mounted on the centre cross bar.
I discard the kit supplied photo-etch item and made a pump from sprue and a propeller from the 'spares' box.

Next up is to fit the engine then add the various controls and pipes to the engine, including those from the cockpit and fuselage fuel tank.

Hi all,
Well just for a change ----

The lower engine support 'Z' struts support the radiator/engine cowl and the engine itself.
When I test fitted the lower 'Z' struts into the fuselage, I found they were leaning rearwards when in fact they should be perpendicular to the fuselage.
Therefore I 'tweaked' them to correct that.

A second pair of 'Z' struts are bolted to the front and rear struts and span up and forwards to attach to the underside of the upper wing, forming the central support structure.





I decided not to use the kit supplied upper ‘Z’ struts and replace them with struts created from micro-tube and rod, for the following reasons:
The photo-etch engine bearer plates and top of the lower engine ‘Z’ support struts have no locations for attaching the upper engine ’Z’ struts.
When test fitted into the location holes in the underside of the upper wing I found that the bottom of the struts on the two upper ‘Z’ struts were way too far rearwards and therefore not aligned with the tops of the lower ‘Z’ strut assembly, to which they should be attached (probably due to my correction of the lower 'Z' struts).
The actual upper ‘Z’ struts were made of three separate struts, not one combined assembly as provided with the kit parts.

To do this I drilled three 0.5 mm diameter holes through the lower 'Z' struts and the photo-etch engine bearer plates.
Then I created four support rods from 0.5 mm brass rod.
Finally I created four brass aerofoil sections that slid onto the support rods.
The upper wing now locates correctly onto the wing 'V' struts and the created brass struts.

Now I have to create the single struts that span between the top of the rear struts and the bottom of the front struts.

Remember - modelling is meant to be fun  ;)

Mike,
    Absolutely amazing work, this is the modeller's art in a whole new dimension! I am really enjoying (and learning from) this magical journey you are on!

Cheers,
Lance

Hi all,
Thanks for the encouraging comments - for this build I need them ;)
I made the cross struts in the same manner but the locating rods for these struts were soft soldered for strength.
A 0.5 mm diameter hole needs to be drilled into the underside of the upper to locate the top of the struts,
