Gents,

 

Apologies up front for the following stupid = questions.  Thank heavens for the LML.  I don’t know how a first time = builder would ever get a plane finished without it.

 

I’m now home from a 5 week fast build of a = IV-P.  The shop is set up, and I’m ready to start some of the finishing work.  As I inventory my supplies, I have:

 

DuPont Corlar Aviation = Finishes 13160S with its Epoxy Activator

BASF R-M Undercoat DP 25 = and its hardener, and

SP – 008A-PT Silver = Plane Copper Coating.

 

My ignorant neophyte first time builder understanding = is that I need to create a ground plane connection between all of the = avionics antennas with the “silver plate copper coating” and that the = DuPont Corlar goes on just before the paint.

 

Is this correct?  What is the proper order of = these things?

 

Should the avionics antennas be = “connected” via the silver plate copper coating before the Corlar is = applied?

 

Does the “copper” get applied directly to = the carbon fiber on the belly?  Do I coat the whole underside or paint = a “path” between antennas?

 

Other emails (Fred Egli) have indicated that antennas = have been mounted directly on the carbon fiber without any ground plane = – and that everything works fine.  What are your experiences with this?  = Need I even worry about any kind of “ground = plane?”

 

What is the BASF R-M Undercoat?  Where does it = get applied in this process?

 

Thank you for your assistance.

 

Regards:

 

John Hafen
