Default Slow tail wag fixed!!!

Hey guys, I've been having a slow tail wag issue, and have read several fliers having the same issue so I went to work trying to remedy this situation. I first noticed there was alot of play between the pivot pins and tail pitch slider. I first put a drop of ca in the groove in the pitch slider to prevent it from rotating which could wear the pivot pins out and then added 1 short piece of small shrink tubing over each pivot pin (cut flush with top of pivot pins) and touched each pivot pin with the tip of a solder iron to shrink the tubing then put the tail back together. Then work the tail back and forth to break the shrink tubing in until moving smoothly. This mod took out all the play in the tail pitch slider/pivot pins and the tail now holds solid and smooth. Flys great again, no more annoying wag and loose tail. Try it out

hmm... definitely an interesting solution. Got me thinking about it...
Maybe I'll try it with a stock tail and not one of my lynx tails ?

Still working great. The pins were a little worn down even after a few flights of being in stock form, and I didn't want to keep replacing parts. the shrink tubing is holding up very well

It just goes to show that a slow wag in a hover is always mechanical. If you're tweaking the electronic gains to get rid of it you're probably chasing your tail...pun intended.

I do that with all my helis' pitch sliders regardless of size. There is no reason for the grooved part to spin since there's a bearing in there. I use a dab of JB weld instead. Also, it isn't the pins in the pitch change arm that wear down. It's the sides of the groove on the pitch slider that get ground away and the groove widens. Whether the pitch slider is aluminum or plastic, it's going to lose out to the pitch slider pins since they're steel.

The pins in this case have flat spots wore on both sides and the pitch slider groove walls are no thinner compared to a new spare slider. Anways the shrink tubing is tough and should prevent more wear on pins. I will post a pic later on, not home right now

I was just tonight taking a look at my tail because after my "inverted tree trim of death" it had a little tail wag. So, operating on the principal - tail wag is mechanical, I thought of this recent announcement of your fix!

I'm still going to do this with my stock slider ( which is currently installed ) when get my Lynx replacement. But, what I found in looking where I had previously missed, was thanks this thread.
I noticed the same, that the small pins seemed to have flat spotted and were no longer a cylinder that fit into the slider with minimal side to side play. Had I not found the problem ( in the pic below) I would have given it a go with the glue and shrink on the pins.

Any ideas why the center would get worn out like that? I'm guessing something out of balance? Or like the pins has this part just worn out from so many flights and a couple crashes too. Lot of torque on that tail at 20k rpm.

Just adding to this thread, if there is a tail wag when I'm just hovering, there is a mechanical reason for it.

***By the way your pics were perfect and explained just what I need to do for this mod. Well done sir.

My guess it would be vibrations on a not so well balanced tail along with wear n tear that you're describing. Thanks for the reply, much appreciated!

it is kind of the " which came 1st the chicken or the egg" situation.

par for the course. I fly the hockey puck out of my 180 and I' m quite ok with replacing parts as needed.

But a mod that will increase lifespan of a part? I'm all for that...

JJ Inverted Productions, aka Jack Blanchard (d12bn on HF) posted a video of doing this to the pitch slider a long time ago on Youtube.

The 180CFX has the same tail setup as the 450X, yet I have never had any movement in the 450X, but do in the 180CFX

Hi guys,

If someone still looks for any solutions to ground pins on pitch lever, remember this trick :

Take pliers and rotate the pins 90deg or whatever you find best to have a fresh side of pins in contact with your slider disc.
