Aircraft assembly

Another big day. I bought some hose clamps, and started by adding the flexible hoses to join the fuel system at the wing roots. Next I connected the pitot and AOA tubes at the wing root.

Then I started working on connecting the flap cables. This was easier than I expected and all went well. Then I lifted the flaps into position and secured all the hinge bolts. It's really a two person job, difficult by yourself. I spent time adjusting the flaps so that both were aligned with each other, and so they matched the lower wing surface when retracted. I also tightened the cables so that the flap moves as soon as you pull the flap lever. I imagine the air loads will change this.

Then I did the same with the ailerons, and set both tips 3/8" above the wing tips, with the bellcranks neutral. I wanted to canter the bellcranks in at the rear, but my pass through cable is already tight in this position with no further adjustment. Then I adjusted the cables to bring the sticks to neutral position as well. This results in a full range of 40° travel, with correct differential.

Then I set the tailplane neutral at front and rear, showing zero degrees laterally. I haven't adjusted the stick position for elevators yet.

I've set the rudder so it's centered, with the pedals moved forward towards the Pilot.

I installed the landing light lens, and sealed it. Same with the fuel tank caps.

Then I used a hole duplicator to mark the holes in the wing to fuselage trim strips. I took them home and drilled, countersunk, prepared, and primed. I'll top coat them in the morning. The GPS antenna will be bolted onto the left trim strip.
