Wing torque, flaps

I need to find a way to get to the aircraft more often!

I attached the bolt that connect the back part of the wings and then torqued all wing bolts. I used about 170 and 820 inch pounds.

Then I attached the little fuel line from the tanks to the fuselage. After that I managed to connect the flap actuation. My flap motor runs in the wrong way, I will deal with that later.

Final task was checking my com radio, I could here coms but with very low volume. Hopefully just a configuration problem.

Wings

Another milestone. Wings are attached (not all bolts are in and no torque on any nuts)

I arrived at the airport early, unpacked some tools and supplies and then started working. First was removing the cowling again, the upper pins really caused trouble this time, must use better lube the next time.

Next was removing the lower spark plugs and letting out the preservative oil. Almost nothing came out of cylinder 2-4 but a lot from cylinder 1. Next was removing the oil, about 1/2 quart came out. Filled with 7 quarts of straight mineral oil.

Removed the plastics from the propeller, connected the main battery and rolled out the RV from the hangar. Now several EAA members started showing up, ran the starter motor with the lower plugs still out, almost no oil pressure on the first run but after letting the engine cool, I got pressure on the second 10-second run with the starter.

I had not gotten hold of or been able to manufacture any drift pins so I had not planned to install the wings today but with all helping hands around, I found two old worn 3/8 bolts and sanded them slightly and trial fitted them on the RV and lubed everything with grease.

Then we got to work, being five people it was surprisingly easy to get the bolts in, what I consider mild tapping with a plastic hammer while the others wiggled the wings was enough.

A big thank you to all who showed up!
