I have a hbfp and it has a bad shake, ck,d flybar seems ok,ck,d blade tracking looks ok, It shakes pretty bad, worse when I change direction like forward and reverse, left and right also tried blades tight and loose, tight is better if I get the blades lined up perfect, but takes several times to do that, has a superskide from extreme and a battery/reciever mount that fixed the balance problem any ideas would be great at this point!
