Does your canopy on the 90 vibrate?

Kind of feels that there is a slight vibration..wondered if anyone got this?

It was. Then I found that my splinde shaft was slightly very slightly bend and my flybar paddles were not equally far from the hub.

Fixed those and its solid now. No visible vibrations on tail fin, canopy or landing skids.

Also I changed the link lenghts. Heli seemed to be in track but when I fine tuned links it got better. I guess bigger blades might fool you or just me lol.

Actually mine is ok but it got this vibrations/ resonance from the canpy. Tail and body was all very smooth.

Can you at least describe if its a low frequency (like 1500-2000 hz) or a high frequency (15000-17000 hz) vibration. Let's try to understand if it's because of the head assembly-blades or the engine-fan .

You should be seeing two different canopies if its because of the engine-fan. You should be seeing a shaking-vibration characteristic if its because of head assembly or so.
