Intend to finish any remaining glass work and priming.

I hope that you get to see it fly some day / fly in it if that is your desire. OC PS: What is the black strip on the leading edge of the vertical stabilizer? PPS: I still have a faint lingering desire to start building something again, but at the age of 83 this November I am stymied by the thought of getting half way through a project and then realizing that I could never finish it or see it finished. I reached 475.1 hours flown on my KIS TR-1 today. ===================== From: Alfred Rosa Sent: Thursday, August 13, 2015 5:32 PM Subject: KIS-List: TR4 move I finally moved my TR4 project out of the garage and into a kit building hangar at the local airport.

Let's say instead of 10 plies of glass, use 5 plies of carbon. What would be the pros and cons of this idea? Good idea or bad idea? What sayeth the list? ________________________________ Message 4 _____________________________________ Time: 03:23:14 PM PST US From: "Tim Yoder" Subject: RE: KIS-List: TR4 move Sorry you can't finish it, hopefully you sell it ok.

It is difficult to tell if wet layup carbon fiber is fully wetted out with epoxy. Also, sometimes the thickness of the layu p has structural advantages. It is also difficult to get carbon to conform to any kind of a corner.

If you really wan t to beef it up use 10 plies of Carbon.

Assuming the strength will be the same (no beefing up) what are the pros and cons of more plies of glass versus less plies of carbon or does it really matter?

I am stunned at the use of stainless steel for those leading edges. My use of stainless steel on my KIS TR-1 was very limited, firewall facing and a few other bits and pieces that I don=99t recall right now. I found stainless very hard to work with and wonder how you were able to fabricate, or have fabricated, those pieces, and how they are fastened in place. I wonder how the different flexural modulus of stainless steel and a matrix of epoxy resin and fiberglass would affect the structural integrity of the wing. See here:** https://en.wikipedia.org/wiki/Flexural_modulus OC **PS: You do have some similar prior wing structures in that the leading edge of the TKS versions of the Cirrus aircraft have titanium leading edges with many, many tiny holes to weep the TKS fluid. See here: http://cirrusaircraft.com/innovation/known-ice-protection/ https://wikiwings.wordpress.com/2014/02/21/cirrus-sr22-g3-tks-inadvertent -ice-system/ ==================== From: Alfred Rosa Sent: Thursday, August 13, 2015 7:02 PM Subject: Re: KIS-List: TR4 move OC, that leading edge strip on the vertical stab is stainless steel Which is reflecting shadow and looking black. The horizontal stab has stainless leading edges also and the wings will have it too. Just a esthetic thing to look cool and stand out from the rest.
