130x shudder

[gary911]

Hi, my 130 has a shudder when you reduce collective on descent is this just another quirk or can it be eliminated.

Thank you.

Same on mine. I think the undercarraige amplifies it. I'm trying to stiffen the undercarraige.

Is there any slop on the swash linkages?
As this will cause it
Make sure the o rings are snug against the links

Had this on my 130x found that the head could twist 10 degrees with the main shaft held firm. I removed the screw from the head block rotated it 180 degrees and replaced the screw... No more twist and flies as she did out the box. More than likely due to the numerous crashes I've had but works fine now. Give it a go, only takes 30 seconds to do.

This can be reducued by upgrading the O rings on the swash ball links 130X Silicone O-Ring Kit

It's worse with the fast response blades. The bullet blades are less susceptible to this, but the upgraded O ring kit as Skyfool mentions is what you need. Put the upgraded O rings on the swash, and it eliminates the judder on descent.
