VIBRATION

[DELO7]

HELLO EVERYONE, JUST GOT MY CX ABOUT 2 WEEKS AGO. HAD FIRST CRASH, AND INNER SHAFT BENT. REPLACED IT AND STILL HAVE VIBRATION (CHOPPER SHAKES VIOLENTLY). ANY TIPS ON WHAT MIGHT BE WRONG? COULD IT BE BEARING MISSING?

check the blades and the lower head pins.

The way I figured it out was I put the throttle stick full left and gave it some juice (not too much) to get the bottom blade spinning until the top one started too... No wobble.

Then I did just the opposite full right and a little juice, the top blade started to spin and the wobble was there.

I changed out the blade I knew was still there from the crash. Wobble gone. Not sure why that blade because it still looked good... no obvious markings of damage I mean.

what should i be looking for

[fubar]

check that the flybar is straight look from the side and the top ,also check that the tracking is ok for the top blades if when in the air you can see two of the blades (side view)instead of one solid blade adjust the link from the blade to the flybar.
