Sorry but I don't understand quite well your problems due to my poor english...


>What the heck is it? No allen fits its not a nut

Yes, is an allen, but metric! And I see that perhaps there is some glue on it!


Be very carefull with the carbon bypass! I took it away after a flame out of the turbine during a very fast passage over the runway with the turbine at minimum. I didn't crash the airplane because it flies so well!!
Too difficult for me to explain in english what happened but I've done 4 flights doing the same passage and all was ok.
Hope it can help!
Ciao
