I installed mine (hydraulic lines) just like it says in the manual. Today I did a test fit of the flap torque tubes. I mounted the support brackets on the aft spar out in the main gear well area, put the plastic bushings in them, inserted the torque tube ends in the bushings, and then bolted the torque tube flanges together along with the arm that goes between them. Guess what? The flanges on the torque tubes rub against the hydraulic lines and fittings. Not by much, but enough to be a problem. I'm going to have to find a way to move the lines or angle the fittings differently. I should have known better than to follow the manual. If you haven't installed yours yet I suggest routing the lines as far away from the centerline of the cockpit floor as possible while still keeping them under the console.
By the way, when you route the hydraulic lines from the bulkhead fittings in the aft load pads out to the over center link rib in the wing center section don't do it just like they show in the manual. If you do they will interfere with the flap torque tube supports---at least mine did. Mount the supports first and route around them. It's a good thing there's a lot of 1/4" tubing with the kit. I've had to make several hydraulic lines twice.
Here are some pictures. First is a shot of the interference. While it sort of looks like the screw is close to the hydraulic line, it isn't really. It's just the angle and focal length of the picture. (And yes, those are hardware store nuts. I use them for temporary fit only.) The real interference is the bottom of the torque tube flange rubbing on the high pressure hydraulic line (on the right in the picture). This actually pushes the torque tube and arm assembly to the right of centerline (left in the picture) so that it also rubs slightly against the nut on the center bulkhead fitting in the aft spar. I rotated the left bulkhead fitting (right side of the picture) just like Richard did (image 3). This got the high pressure line out of the way which allowed the torque tube and arm assembly to be positioned on centerline where it no longer touches the center fitting. If I was doing this again, from scratch, I'd move the two fittings on the right (left in the picture) about 1/4 inch farther from center line, and the left fitting (right in the picture) at least a 1/4 inch farther from centerline..
Also above is a photo of a routing installation courtesy of Richard Ogg (image 3). Richard Ogg has solved his interference by rotating the left hydraulic fitting to face outboard.
On a different note, I installed the flap motor attach plate and found some inconsistencies in the manual. The instructions for fabricating the attach plate and mounting it are in chapter 21. Figure 21:C:2 says to locate the aft edge of the flap motor bracket 17.5" from the aft spar. In chapter 16, figure 16:A:4 it says 17" from the bracket to the aft spar. I've sent this to Carsten so maybe he'll respond with which measurement is actually correct. For my plane it looks like 17" is the better number as everything fits better at that distance. Also, when you get to routing the hydraulic lines from the aft spar to the baggage compartment bulkhead be sure you use figure 16:A:4 which shows routing the
lines around the flap motor. The overall hydraulic line diagram in chapter 3, figure 3:H:1 doesn't show routing around the flap motor and could be misleading.
