Here's a timely tip for you that I found almost too late - very shortly in the instruction set you'll be told to countersink the canopy holes, then open them up to 5/32" and deburr the inside. There is no comment on leaving any of those holes at #40 mentioned - but a page later where it talks about the aft skirts, there it says not to enlarge the holes in the canopy that contact the aft bow until after you use a #40 strap duplicator (hole finder) to transfer those holes to the aft skirts. If you don't read the entire section before building (and have a pornographic memory) this will trip you up. Best bet is to leave all those holes at #40 until you are absolutely forced to enlarge them.
