The 'instructions' for connecting the hydraulic hose between the power unit and the runway were, once again, inconsistent with what I was looking at, so I got it hooked up how I thought it was supposed to go. This plastic line is NOT mentioned in the 'instructions' at all, but I did see a Festo fitting on the oil reservoir so assumed that's where it goes. This line was very stiff and did not want to straighten up, so I broke out the heat gun to soften it up a foot at a time and got it secured to the hydraulic hose.
