Hi again comrades. Sorry for all this, but without you guys ,people like me will give up this sport.
I am very methodical and feel that for every action there is a reaction, ( sounds familiar) but when it comes to helis Ive found this to be so true.
I have serious tail vibes, so I have stripped out and replaced the mainshaft with genuine parts. I have a 450 pro. Spooled it up without the head on and still got the vibes. so..... I checked the tail bar and slider , which all are tight and no play there.......
Then I had brain storm and disconnected the tail servo rod so that I could get a true spool up and bingo..... there was little or no vibrations !!!!!! I have just manually rotated the servo and can hear a click so I suspect there is a damaged gear which is causing a "jump" in that area on spool up.
Could this be it ??? could this teeny weeny click set off a string of vibrations, ? was Einstein right after all lol.
I figured if the vibrations stopped after disconnecting the tail servo rod then the problem lies right there, in that servo somewhere. I would recommend anyone with vibrations to do this check, its quick easy and saves a lot of hassle.
