Hello,
I just got problem on my Trex600N,
ONLY Vibration on HIGH RPM (Idle 1), while on low speed is okay.
The vibration only can see on the landing gear, tail look ok no vibration.
while hovering on Idle 1 high RPM, the sound(air) like not too smooth.
I've checked my heli as:-
1)Rotor Head- I changed my friend rotor head set to my trex 600N, but still vibration on high RPM, while my rotor head fit to his heli, is ok no vibration.
2) Tail.. Tried drive belt and T.Tube. also same happend.

Question:-
1)Anyone have vibration problem on main frame Part.
Like vibration from engine(os50), Vent.fan, clutch
and gear??
2)The 1.6mm GREY Main frame for Trex600N can stand for hign
RPM?? (or need change mine to 2.0mm?)

When you used the different head did you also use different blades, maybe your blades are unbalanced.

On my 600N I could see the fuel shaking at 2100rpm, after I rebuilt the motor, all was smooth again. I checked and re-checked everything on the heli, even weighed the symetrical head parts.
