For sure that canopy is a winner. Looking forward to seeing the latch.

From what I've read on-line CF shafts run from 0.275" to 0.400". The ones I used I just looked at in a sporting goods store and thought "that looks about right". There is a whole science of CF arrow shaft stiffness, called "spine" that comes into play in archery. I'm like you though, triggers I know!wesley. said
On the carbon arrow shafts are those all one size or can you get different diameters? I know absolutely nothing about bows i like pulling a trigger!

LATCHES – IDEA #1. Use these little cam-style fasteners that are common on assemble-yourself cabinets/etc., since I had a whole bag of spares left over from a home project.
The idea was to have the countersunk-head machine screw mounted in the canopy rail which would engage the locking cam (mounted in the fuse side) when closed. I made a mock-up and tacked into place in the Krill.
Although it did work fine, after a number of lock/unlock cycles the cam started showing some wear. It’s made of softer “pot” metal and is really not designed for lots of cycles. Also, even if it worked fine, I would still need to use a screwdriver to open the canopy….strike 2!
So…scrap that idea.

LATCHES - IDEA #2. Then I discovered these very nicely made spring-loaded slide latches, and voila!
After locating the proper position and slotting the fuse for the latch levers, the slide latches where glued onto a light-ply shims, which were then glued inside the fuse.
I used some high-density polyethylene blocks for the locking pins to slide into. They’re held in place on the stock canopy tab with Hysol and a countersunk machine screw. The original screw holes in the fuse will be filled....the only things showing will be the two small slide catches....pull together (toward each other) to unlock.
The whole process was way more tedious than the hinging, but the final result is they lock very securely and require NO TOOLS to open or close the canopy!

Here is a thought, drive the canopy from a slow geared down servo.

Neat stuff. If I had know about them earlier they would have been another option. However I'm done fiddling with the canopy....and besides....on the full scale the pilot has to manually unlatch and swing it open
While we're still on the canopy, I found this great scale sliding canopy vent from www.itailies.com Now Mikey can get some fresh air while taixing....or let the heat out from the pipes under his ass!!!
Also made a little aluminum handle to assist opening the canopy

I like 'em "BIG"!
Really love the scoops on the side of the fuse and the canopy. The grab handle is very cool too.... Just curious, where did you get the spring loaded locking latches? I would like to get some for an upcoming project. They look to be very good quality.
