Let's see how you're going to Cut-Up that Cowl, for those Jugs to Pop out?
I am still waiting on Head-Pipe and Canister-Mount from DA to Complete ours.

It will be a template job. Maybe tonight can post some pictures. First out and enjoy the weather.

Final muffler fitting, and first left jug template. A fold line is present at the vertical scribe line. The template then is taped to the fuselage, and the engine removed.
It may be needed for cowl fitting, to have the marked section fixed to the fuselage. Will see to that later.

Fit the cowl with engine removed, and transfer the template outlines to the cowl. Add some extra spacing to the outlines. Then Dremel out the outlines.

Like anticipated, the cowl will not go over the engine, so a section behind the left cylinder must be assigned to the fuselage. To that end, it must be sparated from the cowl, and later fastened to the engine pod or stand-offs.

Efishensea, bye for now. Your turn. I'll be back for baffling the twin when ready.
I am very eager to hear about your DA85 fit 'n fly.

My engine must move over to the right slightly (5mm) to get the prop hub to line up with the cowl front. So this makes a second cowl jug opening necessary.
With engine fitted, the upper cowl fastening points are inaccessible. Must think of something here to fix this.
In the meantime, I also prepared the two linkages for the cable pull throttle and choke operation. Some more pictures. The final fit approaches satisfaction.

Interesting thread and nice work! At least one of the early 122" Decathlons have found its way to Sweden and Iīm working on it. Sorry my thread is all in Swedish but you can have a look at:

Kjell,
How do you fasten the upper cowl screws?

Hi, my engine is a bit slimmer than yours so I can reach the screws with a cut off hex wrench (with a ball tip so the angle donīt have to be straight ) silver soldered to an extension with a curled nob. I have been thinking of to attach the screws to the bulkhead, lock with CA and cut the head off. Then attach four small magnets in the bulkhead beside the cutoff screws and the corresponding washers fixed to the cowl. Then the screws act as guiding pins and the magnets just lock in place. Have not tried this yet but I think it would work OK.

Pe would it work if you removed the blind nuts from the firewall and mounted them in the cowl ring? Then you could put the bolts in from the inside of the cockpit.

Nice idea! I will have to check that out. Maybe used with loooong screw head extensions. It would be better than have the screw heads external on the cowl.

checked it out, but this opens a new can of worms. I will probably go with alu angles on the firewall, and external screws, painted oracover red (2-component paint). Will have to check out some decent Decathlon detail pictures to see what at least looks stand-off scale. I abused the looks already by the two cylinders sticking out.
