looking for help.

i have logo 500 with old style vbar, i upgraded it from 3.6 to 4.0
all was good for about 6 flights, then it did the funky chichen about 20 feet high, i hit throtle hold and after a couple of seconds it all stopped, i just managed to land it with out damage. the only thing i could find is the carbon boom support had come unglued and it was rubbing up and down on the threaded bar that it should be glued to,it was like a static spike. i have the tail earthed to boom and boom earthed to motor mount, continuity is good,
do you think i could get a spike from boom support chattering in flight.
or any other ideas

Thanks Paul

No but bad vibes will do that also. If you vibrated a boom support loose you may have some other issues to figure out.

when i went for test fight after up grading firmware i didnt take laptop to alter any thing. the gain was a little bit high on cyclics which did cause the heli to shake a bit as gain was high i think this is what could have caused the support to come loose.

so as this has broke the glue joint it could of been a vibration problem that caused it to do funky chicken

I had a 600 logo do the same thing last week, checked the log and it had bad vibrations, which turned out to be a bad thrust bearing in the tail rotor and a bad mainshaft and it had other issues that Im taking care of. It was a used heli that Im rebuilding.
Have not had a chance to fly it yet, but Im certain it will be cured.
