Hopefully this is the last significant update on the torque tubes for a while. A made a few small adjustments to the floor ribs and that seems to have improved the friction issue. There’s still some resistance, but I think that’s unavoidable since there are 4 bushings. I recorded a …

Torque Tubes Part 3

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 …

Torque Tubes Part II

With the joysticks done, I turned my attention back to the flap and elevator torque tubes in the center fuselage. I quickly discovered that none of these will go together easily; each bracket that holds a bushing has needed *some* kind of modification so far. For these torque tubes, the …
