Hi Dwayne,
Looking with interest at your build - I did mine a while back and used a length of 1 mm Brass rod as a main spar to support the two wings, as the kit attachment I felt wasn't strong enough to support their weight.
The drills 'Des' mentions are good, but I think are designed more for drilling PC boards etc. Unlike standard HSS drills, I found they tend to 'bite' to much and effectively corkscrew their way into the plastic. Consequently they bind up/jam easily and snap. You'll need to keep backing out the drill and make sure the plastic swarf is regularly cleared from the drill.
I have the Windsock Data file #58, which covers the Types N, I and V. If you want to, PM me on the forum and I'll email you a PDF copy,
Mike
