Evo 50 Blade flutter

[Helio Addict]

Just put my Evo together and not long into the first hover check, one or both of the blades began to flutter something awful. It acted like one of the blade had gone severly out of track. I took the blade grips apart and checked to make sure all the bearings were in the right places and I've also tried a set of blades that I had on onother bird but the problem persists. Any suggestion would be appreciatedj!

Double check thrust bearings main grips --little ID to the outside

Metal plates holding down servo? without the brass bushings?

Is it new or crash rebuild?

Are you sure they are in track well?

OK, found a bad pitch servo, flys great now. Didn't know that would cause the blades to flutter!

Yes it will ,,,But I don't understand why?? You would think that, pitch would have to be diffrent between the two blades for flutter and that shouldn't cause that. But Glade you got it right :wink:
