I had a professional come and do my pitot-static/Mode C checks today, and we had to chase leaks at the Dynon Air Data unit. He says this is not uncommon on Experimentals that use the push to connect fittings for plastic tubing, and he greatly prefers the Nylo-Seal stuff. As it turns out, my leaks were between the metal bodies of the push to connect fittings and the inputs on the Dynon, and tightening them up took care of them, but if you're planning a system, use the Nylo-Seals, AND put tees in the lines (both pitot and static) somewhere accessible, capped, so that the tech can easily hook their gear to your system. Works better than trying to interface to a Pitot-Static mast. He also said the static ports on RVs ALWAYS leak unless the builder smeared the whole business with polysulfide.
One more punch list item checked off....time the secondary ignition, calibrate the heading sensor, and then call the DAR.
