Hi Andy
Sorry about your failure on your uh-1n hope its not too fatal

Thanks I am assuming by TT you are referring to the torque tube at the take off from the front

I had a issue with the torque tube it was shaking the ends out of sync so I removed glued and pinned them in place and fitted a second bearing holder on the torque tube

Tried to do a search for your post to no avail have you got a link to the thread

I have sorted my vibration issue the first thing I found was I thought I had fitted a 14t pinion not so it was 16t I am running a scorpion 1000kv motor

second thing was the base on which the mech's sit on was like a drum so have re-enforced with 3mm ply could not do the whole floor as the tail boom would have been too high to get through the fuz

third but not least I am using spin A-symmetrical blades 515mm they have a cord of 62mm nice blades but after the paint job I did not balanced them they were 0.62g on weight difference

Now I have reassembled and had several flights with her she is running good vibration issue seems to have gone and the diagnostic's on the Skookum 720 confirm this

All in all its been a bit of a venture had me scratching my head not knowing where to go to next but I got there in the end

The world is round you can run but you will always end up where you started from

The fuselage is a write off - too many small cracks, a few big ones, skids destroyed, both front doors broken off, RHS sliding door ripped off, broken formwork which is not accessible from outside.

It was the TT where it joins the Align TT-end fitting at the back end of the long TT - where it enters the angled gearbox.

here is the HF link - easy to find;
