Lots of small fine tuning and details that takes time. patience and attention. One of thse is behind the panel where I wanted an additionnal support for the throttle & mixture cables. That piece had to be attached to the sub panel and although I would haveprefer to rivet it, the lack of space forced me to drill (with difficulty) 2 holes and secure it with 2 #8 screws and nylon locknuts.
I re-runned 2 wires because "they were in the way, I cleaned the 3 cable stacks properly, secure some fittings, add the RG4000 cable from the radio and tons of other little things.
Sliding in the cockpit under the dash is not simple ... my size is really limit !
