Pulled all of the clecos out of the rear canopy today, I used some 3mm acrylic strips to help keep the PETG from rippling too much when gluing it in place.

And with it removed showing the oversized holes for the clecos.

I went through all the holes with the 2.5mm drill bit ready for the rivet and started countersinking all the holes. I put a few clecos back in to hold the canopy in place in case of the sealant starting to peel.

I also alodined the landing gear clamp parts and then painted the clamps and hangers with the 'chrome' paint. I will let the paint on the gear fairings harden a bit longer before wrestling them back over the gear legs.

David,
your parts look good!

When I have canopies I am considering selling some if I can make them to a good standard! Shipping might cost more than the canopies themselves.

I have also heard that the R22 helicopter is similar in control response to the CriCri and I can fly one of those around no issues, hovering it is another story but I would like to try again soon.

I've been making some more progress but keep forgetting to take photos and put up an update.
Today I made a folder for making the nose vent fairing. I had these cut out from a long time ago, so long ago that the PVC mask is starting to break up really easy. At least it still comes off.

I scuffed up the inside with the scotchbrite pad. The camera really doesn't like to focus on it ;)

After quite a lot of thought, I made up this contraption to do the folding. The issue is that there is a double fold but the end of the fold is flat. Folding 2024 one way and back flat again will cause it to crack.

With this gadget I can fold both folds at the same time while keeping the flat part from being folded. I have to hit it on the sides with a heavy hammer to get it folded but it does go down really well.

And voila' a folded vent cover!

And the underside, I did alodine the inside once it was folded and promptly forgot to get a picture!

AND after all that, the jig is folding things 2mm too wide. I might be able to use this one, if not I have already trimmed the center form block a little so that the next one should be spot on.

looks nice....appears to have good radius (would crack if not)..did you hammer each side straight down with the center clamped to the table?

To start the bend, I hit the head of the bolt at about 45° at the longest joggle end and once each fold had started I stood the jig on its side and hammered away till the bends were 90°. I cut about 5° springback allowance on the edges of the jig.
I eyeballed the radius and gave each piece an equal number of swipes with the sanding block. Being .016" it doesn't need too much of a radius.

Shannon, quick question… do you know the distance from engine center line to the opposite engine center line?
