Hi,
Interesting post. I have also a torque tube issue. There are a lot of AA5 (AA5A, AA5B also later years of production) out there with no bolt on the outside brackets! I think this is a big risk and wonder why nobody is talking about.
I saw there are different modified torque tubes out there. One with taper pin, other with one bolt and another with two bolts 90 degrees offset on to bracket where it is mounted to the fuselage. Perhaps two bolts also reduce the material durability?
Which one is the preferred torque tube modification?
Does anyone know which adhesive is used for the cold bonding on tube jointing sleeves and which size of bots should be used?
Regards
