Another 2 hours playing with torque tubes. I really don’t know what is the acceptable level of friction. It bugs me that the bushings rotate freely on the tube when it’s out of the fuselage, but the when I put the tube in and start clecoing down the close out ribs, it goes to crap. I saw that another builder got advice from TAF to wait until the side skins are on before attempting the torque tubes. I think there are a few more things I can try before moving on, per the photos below.
