Hi Guys,

Finally got someone who knows what they are doing to look at my heli yesterday and set up the correct pitch / throttle curves, I had mis-measured the flybar and had the paddles 4mm out!! Anyway, now with that sorted the heli still has the shakes, it sorta swings in a circle below the rotor head, which leads me to believe that the problem is in the rotor head (as that is dancing as well). Could anyone suggest where the problem might be, bearing in mind I have checked the mainshaft, feathering spindle and flybar? Please note that the headspeed is set to 1800RPM and the chopper is a Morley F1 Carbon 46 with an OS 50 Heli Engine.

I couldn't sort out the vibration problems with the guys in the know yesterday because I was receiving huge glitches where the heli would suddenly leap on its side (there are some metal pipes under this certain part of my flying field and I am flying PPM). Luckily there was a BMFA 'B' test pilot standing next to me at the time who managed to save it for me.

Many Thanks - Trev.
