It shouldn't at all. What kind of lube do you use and how often?

I use 3n1 oil and give it a good coating when I have it out for any reason.
I also auto every flight, actually sometimes several per flight. Probably
hundreds of autos w. it over almost 300 flights, no issues.........so far.

The 09-12 year version of the 600se. Running between 690s and 693 blades.

Also, could RPM be a factor? If you are running higher HS and hard 3d, that
could stress it faster? I pretty much am running mine at mid to lower H/S.

I'm running around 1800-1850rpm.

This is my second OWB. This one has been put in for about 2 months.

What kind of lube do you use on it? Also do remember reading a thread about
some guys having one-way issues, maybe on the 2013-current models? Believe
it was on the 'other' site.

I simply have not had a one-way fail on any of my Logos so far......10, 500, 500se, or the 600se......

I do have a habit to end a flight with autorotation but I do F3C flight or big air, etc with my Logo 600SE.

I don't have owb issue so far. They are quite reliable. I use Align owb grease that comes with Trex 700.

It is possible it is the sleeve in the OWB that is the problem. It might have "flat" spots where the bearing digs in, and these flat spots are just enough to allow the bearing to flex too far and lockup. That or the outer diameter of the sleeve is too small...or the auto hub is bad...

No sleeve on the Logo 600SE OWB, it slides onto the main shaft. Only use 1-2 drops of a SILCONE based lightweight oil during assembly. The 600SE is limited to 1800HS. If you are flying over that you will kill the OWB. You can also use the 690 OWB setup and it will be good to 2100HS...

1800 head speed is low for a 600 size machine. Over five years ago, I owned a logo 600, and loved that machine and never had a one way issue. I sold it, and regret it. Now I got me a brand new in the box logo 600sx, and the one way died on my fourth flight. I have the head speed at 2100. I flew my old logo at 2200. So something has changed. Just got a new bearing from Mikado this week, but the rain is keeping me from flying.

A logo 600SE is a machine that swings 690s. A little more stress on the drive train.

If the OWB is dying, typically it is a lubrication or shimming issue (extra stress on the main gear at a slant).
My Logo 600SX is swinging 600s, 2200 HS, and 14 degrees of pitch....not take by any means.
Kyle Dahl just laid the absolute SMACK down on my Heli this weekend at the Abeline Chopper Madness and no failures.
Sure there are a few that will fail but wholesale failures are not common unless the setup is not correct.

My bad. I forgot about that.
I am still having one way issues though. If the new one way does not work, then I may start a new thread.

Autos should not hurt the OWB.. i do about a half dozen per flight on my 700 gas Trex and never caused an issue with it.

In fact, unless you are bailing out of it at the last minute and slamming the bearing with full power I think an auto is probably easier on the OWB than stick banging 3D.
