The install of the ADAHRS Dynon SV-ADAHRS-200 (Air Data, Attitude and Heading Reference Systems) in the Tailcone is difficult. I guess working over head made it really tough. You have (3) 1/4 .035 plastic lines that connect to the unit from the Pitot, Static and AOA information lines. The lines have to be prepped at the unit right, 15″ from center of the bulkhead behind the unit with true square cut ends. They connect by inserting the lines into the front 90 degree couplers on the unit. You also have all the wires that connect to the unit to deal with as well, connected by a 9 pin D-Sub connector.
The video below will run fast until I get to the ADHARS unit install. No sound.
