thanks Guys,for the new to canopy's and screws, for me the key for doing a clean canopy mount is to pre-drill the holes large enough so the screws don't flex the plastic, a snug fit in the hole is good but don't try to screw through the plastic without a pilot hole.

when placing the canopy in position go slow the first time through so the fit is nice and tight to the fuse,and there is the smallest gap, a poorly sealed canopy can flex and weaken the holes.

then harden the holes with thin CA after taking the canopy off,so the screws don't pull out or damage the fuse skin, if the screws land in a area that is just thin wood then add some small balsa or thin ply blocks so there is some strength to the screw hole.

the little cap head screws are pretty nice looking, here is another example using the button head screws
