REFLECTOR: Canard Cover and cowl attachment system

[Scott Derrick]

Chuck,

Yeah I keep a ready supply of new stainless screws on the top of my tool 
box.  I refuse to use a worn looking screw and toss them in the trash.

I can see how I could do the hinges where the cowls fit to the wings, 
but the fuselage junction seems a tough one? 

I don't like the idea of the piano wire coming out into the arc of the 
prop.  That would require a bullet proof secure method.

I'm surprised you can't get a 3/4" torx screw?

>Scott, I concur about the screws and washers.  I do a little Irish dance every time I strip a Phillips head.  Fortunately, out of the dozens on the cowling and dog house, I've yet to lose one through the prop, at least I've not noticed any memory marks on the prop.

As a half-step, I'd like to go to the torx screws but they don't make any screws 3/4" long, which I need to reach the blind nut on the rear attachment points, so I'll just keep stripping Phillips.
