thanks man, I'll check it all out one more time, it don't seem that it shook this bad in the XL chassis, but now taht I put tthe HDX450 chassis on it, it's got the shakes.

I'm thinking maybe that lower main gear or the autorotation shaft also... I'm going to swap them out and from there I'll keep looking...

normally, this is fun for me (finding problems), now it's gone on too long and has become a frustration... I've thought and though about it, and now both of my brain cells are too tired to think anymore


oh yeah, I'll throw the tach to the head also.

when I put the flybar in, I just measured it even, I'll try your route and see if I can get the change there.
