Brief Description: Com/Transponder RG400 and conduits
|
|
I hate the thought of "fishing" cables through tight spaces now and God forbid, later. However, with the help of good Conduit paths, it can be made a little easier. Both spar ends have a 1.5" hole cutout to pull wire and antenna cable through to attach to the wing, BUT I don't like this. Guaranteed to get water in the spar this way. Instead I've drilled 2 small 1/4" holes on the forward side of the spar that will allow the COM and Transponder RG400 cables through. Plus, I've added another 1/4" hole on each side that now houses Nylaflow conduit for the nav/stobe light wires. No more fishing. After these wires are run and plugs attached, the 2 large holes will be glassed over for good. I will then add a small amount of RTV to the cable openings ensuring the spar is weather tight. Last thing I need are Wing Bolts that are Rusted out, 20 years from now.
After this, I decided to run both the Com and Transponder RG400 cables through the spar and fuselage. I bought like 35 feet I used about 25 of it. I ran the Com through the right side and the Trans through the left side of the fuse. Both have plenty of service loop lengths in them at each end and are labled. Now they wait for Harrison Avionics.
