This is unlike Armstrong, where any wear will cause slop because the assembly screws aren’t pulling the joint tighter.
So good to know, thanksairsail wrote: ↑Sun Oct 18, 2020 9:41 pmIt’s the nature of a taper fit, they settle over time with use and require a retorque. The taper moves ever so slightly into the corresponding hole and the screw looses torque. Most of the pressure is on the front of the fuselage as the wing is pushing upwards and your weight downwards hence the front screw loosening.
This is a common problem with tapers, but the advantage is a very strong stiff joint. I work in aviation and we use tapers to mount the rotors on a helicopter. These require a retorque several flying hours after install as the taper settles. We can retorque the joint sometime 5 times in 50 flying hours.
The ultimate fix would be a stainless torx bit, that could be carried to give the joint a retorque during the session.
