Next, I have the decals affixed to the seat and fuselage halfs.
On the second MG I have bent the belt feed from aluminum and glued to the MG. Was so taken even the first mg.
Also the two struts supporting the ruder bar.
Now the Copper State have come parts. There are the Clerget engine, Jacobs Decals, German Fokker DR1 and instruments set.
Cheers
Martin

Have now started passing the Clerget build engine for the Jacobs Fokker.
The resin parts are beautifully cast but I will also perform here or attach a few changes by selfmade. Here you can see already the first. Inspiring example are drawings of the Sopwith Camel.
Also, it goes to the Floor plates on. The foot plates I've cut out of thin aluminum and glued. The wooden slats to be his plastic strips of 0.5 mm and are already painted wood colors.

The two bottom plates and the second MG are finished. Must be still painted.
The engine back is almost finished with the changes.
The cylinder is mounted on the engine housing, made holes for the push rods and bulkhead mounted new engine reattachment.
The hood must be thinned.
Cheers

Looking very impressive.

Are you going to change the engine to a Oberursel UR II? That is what the Germans first installed in them.

Thank you for the update and history lesson. I learned something new every day.

Do you know more info on why he used that engine and not the one issued? Was it taken from a downed Camel?

Sorry for all of the questions. This is just a fascinating project you are working on.

Sorry Sam,
but many German flyer use instead German Oberursel engines French or English engines because they are better quallity and more hp.
I don`t know from what Camel it was.

For more on Ltn. des Res. Josef Jacobs see Cross & Cockade Intl. issues;

Vol. 25 #2 1994 “Jasta 7 under Kobes Pt.I”
Vol. 25 #3 1994 “Jasta 7 under Kobes Pt.II”

Herrn Jacobs started offering bottles of wine and champagne to anyone who could bring him an "intact" or sealed rotary engine especially important was the rotary engine oil. Jacobs preferred the rotary powered aircraft as his personal mount. When he acquired a complete Clerget motor he had it first mounted on 450/17 using the attached propeller. The prop was later damaged and another British prop for the Cleget was attached. At one point 470/17 also had a Clerget but it may have been the same one mentioned previously or another. The Camel (Sopwith F.I) used a Clerget that offered 10 - 20hp more than the Oberursel Ur.II motors issued with the Dr.I.

He had two Dr.I triplanes at the same time, these were 450/17 and 470/17. The Dr.I was being phased out in the summer of 1918 so if he wanted to keep flying them he had to get the castor based oil. Later Germany started offering the synthetic rotary oil. Fok. 450/17 was destroyed on October 3, 1918 while fighting Se 5a aircraft.


The ultimate fate of Dr.I 470/17 is unkown, but he did end up marking it with his personal motif (his combat records bear this out) his last use of the machine was in late October. He was at the 3rd fighter competition in Berlin when the war ended.

There is no evidence in the public domain that suggests the Clerget motor(s) he used were or were not from any of his combat victims.

On the engine debate, the Oberrusel was a near copy of the 110hp Le-Rhone engine. Camels could have either the Le-Rhone or the 130hp Clerget (or less commonly even the 150hp Bentley BR1). The Clerget was technically superior to the Le-Rhone but more difficult to work on, even tho many maintenance operations could be done without dismounting the engine. The Clerget Camels were a little faster but one of my references indicates the Le-Rhone engined ones climbed better. That probably has more to do with the engine/prop match. I shall watch this, I have both this and the Camel in the stash and I have built one before as Voss' aircraft, nowhere near as good as this. Waiting to see how you do the steel tubular fuselage frame

Here it goes a little further.
Aileron corrected and sanded,
Cable guides and internal control cable mounted drilling
and axle fairings changed.
Engine will be ready tomorrow. The last two ignition wires are then attached.
Burred, further components and primed.
Cheers
Martin

I'm impressed wih the amount of information you have to make changes. I never take measurements to see if things are incorrect. But, if something looks suspect I will fix it.

Great work so far!

Thank you Gary for your compliment.
You need many Information like books, Internet and other to build near a correct model.

Top wing inside and ailerons with control lever are finished.
Rudder before and after correction with control lever. The hull is behind even shortened. The struts are primed ready for painting.
Tailplane with elevator are too large. And with pencil correction. Must have also shortened after the hull cuts.
Middle wing inside is too long. I don`t know if I make a change quote here.
As the last of the finished engine from the rear. In the front I drilled the propeller shaft.
Cheers
Martin

P.s. I think my build needs always many month work!

Martin,
I can appreciate your dedication to detail. However, sometimes too much correction takes the fun out of a build for me.
If I stay on a model too long, I get tired of it, or become attracted to building another kit. So I try not to get too mired in the details.

Still, you are doing great work.

I started again to build on.
The axis wing on the bottom changes done.
Fuselage reduced by approximately 5mm, the end of re-sanded and filled, for the tailplane struts the holes (they are wrong !;).
Tailplane and rudder new representation of the ribs on the right site attached with thin drawn threads.
What is missing is the connection between the two rudders and the control horns.
Cheers
Martin

The fuselage end is ready sanded.
Shortened lower wing at each end by just 2mm and sanded.
Reduced middle wing to size and glued the parts. For the struts attached new and old holes with putty closed.
Elevator, rudder and aileron completed. All can now be pivoted.
Cheers
Martin
