Hi Paul,

>>and align with current bit size

This is an important step, so if you do this, and balance your new prop, you'll at least eliminate vibration from the prop. FYI, my 2.6 vibrates a little at low RPM, but less than when brand new, and not enough to vibrate the control surfaces at alll.

>>They recommended using quick setting JB weld which I got from them. 2 of the rods came loose after 4 flight

I don't know what went wrong on this. I've used this exact setup on several planes and have never had one come loose, and with mine it is nearly impossible to get the titanium ends out even if you wanted too(I've tried).

Here are a couple of questions. Did you rough up the inside with sandpaper? Did you clean out the inside of the rod with alcohol, or other non-oily cleaner, after doing this, until there was no signs of black residue? Did you let the JB Weld dry for at least 24 hours?
