(page 10-09) Static system...                                           

Took a while to decipher this.  The pages sent inside the ziplok with the static stuff refer to an RV-9, so the diagram didn't match the build manual.  Also, the HomebuiltHELP videos (the biggest bargin in homebuilding) show locations for the various bits which don't match the description in the manual.  Both showed the plastic tee on the side rather than top center as the manual specifies.  The manual calls for heating the 1/8th-inch tubing prior to slipping over the fitting, but this wasn't required.  For the transition to the 1/4-inch tubing it was quite necessary.  The procedure calls for slipping a short piece of 1/8th-inch tube over the plastic fitting, then slipping the 1/4-inch tube over that.  I slipped the 1/8th-inch tube on (no heat), heated a cup of water to almost-boiling in the microwave, stuck the 1/4-inch tube in the water for about 30 seconds, then slid it on.  Worked perfectly.  Very tight.  I'm wondering now if heating the 1/8th-inch tubing, though not required for the slip fit, would have somehow helped the bond with the plastic.  If I had it to do over, I'd do this.

The other 1/4-inch tube shown is for the ADAHRS.  Not sure how this fits into the grand scheme.  The zip ties are not pulled tight yet.
