Did some searching but all old and the emails don't work.
Looking at a retrofit of an RV6A with a Dynon AoA Pitot.
Just done an RV8 but the 6 structure is a lot different. Looking for routings of tubing etc to the rear mounted ADAHRS.
I can't help on the ADAHRS but I did do a Dynon pitot retrofit on my RV6. I'll post my installation in case it helps.
In my initial installation I had the pitot line between the fuel tank and the spar. I removed the fuel tank and routed the new AOA and pitot lines the same way. I mounted the Dynon pitot inboard of the inspection cover and fabricated a stiffener assembly that connected to an existing vertical angle on the aft side of the spar.
If the photos are not showing try this direct link to my shared
RV6 Dynon Pitot installation photos showing what I did. As always there would be other ways to accomplish the installation.
Here is the finished view looking outboard with the fuel tank still removed. I mounted the Dynon temperature probe in the hole for the original Van's pitot tube.
The new opening inboard of the inspection opening.
I did NOT use the Dynon supplied aluminum angle stiffener on my RV6. I came up with this instead. This is a photo of the assembly before installation.
The Dynon pitot mast mount installed in my RV6.
Pitot and AOA line routing through spar opening.
Here is a view of the finished installation looking inboard. Before I did the installation, I verified I had plenty of clearance between the stiffener angle and the aileron push tube throughout the range of motion. I removed some of the stiffener angle to make sure I had ample clearance for the pitot heating wires and the pitot and AOA lines.
Hope this helps others for RV6 installations.
