[QUOTE=Whiskey Kilo Wanderer;10454994]I’ve had similar issues with the Rans S6 Pitot / Static system over the years.
FWIW.
Rans S6-116, U.K. .We relocated Static to a new port, namely a thin metal button with pin-hole attached with butterfly nut through a small (soldering iron tip) burnt hole in in LHS of fuselage fabic - about half way up the side - and just about reachable through the inside to connect the pipe.
This give very close to true airpseed up to about 100 mph.
