Sorry I was thinking of the front bearing not the rear. My reply was totally wrong.

The Hyper 50 rear bearing is crap,not the motor.I love the Hyper 50,makes very good power.After 32 gallons of Wildcat 30% performance the insides still looked new and still ran awesome with a Boca rear bearing.
You pic isn't clear but im guessing it had the known rusty bearing right?

Many people find that the rear bearing will do this even if flown very little and allowed to sit. The residual fuel attracts moisture and the bearing corrodes hanging on your wall.

Having said that, I had a .50 Hyper for years and had no problems.

Gee, a bad OS 50 Hyper bearing. One of about 10 million posts already here on that subject.

Buy a new one, put it in, go fly. Spend a few bucks, replace it once a year. Spend a lot of bucks, replace it maybe every other year.

It's the cost of doing business. Catch it before it falls apart and goes through your motor. Listen for the tell-tale rattle at idle.

Yes -- My first one went out after one tank. The last one is nearly a year and a half old. Go figure.

-----

Yes, we've all seen worse...

-----

The stainless-steel races aren't any better. They may not rust as rapidly, but they tend to flake off bits of metal when they start to go that will take out a piston, cylinder, and ring if you don't catch it early.

Ceramic balls, well, when the bearing DOES go, the ceramic ball takes out everything in its path.

-----

I get mine from RC-Bearings.com. Inexpensive, work just fine.

Typical OS 50 hyper rear bearing. Get use to it if you fly that engine. Like dkshema said replace once a year. That's the only thing I hate about that engine. OS came out with the new 55 and has the SAME junk bearing in it.

Damn that ground is hard! When's the right time to get out of this money sucking hobby?

I pull the fuel line off my engine and run the starter for ~5 seconds after the last kick to blast all the fuel out of the engine. Since I've started doing this my engine bearings last longer.

Well then, if people didn't post the same stuff over and over again there would be nothing new here on RunRyder to read. About %80 of the post out there are a repeat of something in one way or another.
Let's see, how many of these have you read, "oh my heli wobbles", or "oh my tail wags". Then of course there's the guy who has to ask " what's better, a Trex or a Raptor". So to answer his question half the people will say JR or Mikado. That's nice, but it's not what he asked.
And the best part is, I'm sure I fit into about every stereotype I just mentioned.

Come on, give the guy a break.

scott, i think some people get frustrasted with the lack of effort shown by others - new or not - at doing their own independent evaluation or research on a subject. when it's something that has been beaten to death - and in this hobby there are plenty of things that fit that description, then yes, a few minutes with google will yield vast quantities of useful information, and make the original post moot.

now regarding your post about what is or isn't proper etiquette - this the internet, and when you post on the internet, you immediately become fair prey and fodder - there is no etiquette aside from what the site owner feels is and is not appropriate. it's the cyberspace version of a shark feeding frenzy. So when you start a post with "Ever seen this?" on a subject for which thousands of words have already been written...well, you fill in the response. yes, some of us need to get a life...but that's a different post for another time.

I, and a multitude of others have shared your frustration with the bearings on an OS 50.

Four gallons huh consider yourself lucky 4 gallons is the longest one ever lasted for me. I have flown that much in two weekends.

I will never spend another $$ on an os product this rear bearing problem is just to generate $$ for os when the pos bearing eats the engine also.

ENGAGE!!

I've seen them go in a gallon or two and I've seen them last for years. I use the inexpensive bearings from rc-bearings.com or precisionmodelbearings.com

Don't run the engine lean, run the fuel out at the end of the day and add some oil (like air tool oil or ATF) to the engine if it's going to be sitting for a while. These hints seem to help me a lot.

Original question:
Any one ever seen this.
Answer from all those self-proclaimed Helicopter Gods:

Yes.
So yes I have seen the multiple posts on this and other similar postings.
Then why ask "if anyone has ever seen this?"

Your research would have answered your own question, negating the need to ask it yet again on a public forum and open yourself up to answers you may not be capable of dealing with.
with the intention that maybe something new has been developed that might bring some light to the situation.
Your research would have found that there is nothing new here, and no new light to be shed.
Any feed back Idea's or what you did if this happen to you would be greatly appreciated.
You GOT feedback. Fix it and go fly. Sources of replacement bearings. How often to replace them. What to look for (and listen for) to prevent complete bearing failure and engine loss. Recommendations on what bearings seem OK, and what to avoid. Some replies said they'd never buy another OS engine ever again.

You got a lot of information on what people did when it happened to them. The answers came from those "self-proclaimed Helicopter Gods".

If you really didn't want people to reply with useful information based on personal experience and knowledge, don't ask "if anyone has ever seen this." Maybe state that your OS 50 rear bearing is toast, tell us how disappointed you are in the event, and move on.

If you don't want "self-proclaimed Helicopter Gods" to chime in, then perhaps post your question in an airplane or off-road RC car forum.

But don't complain when people answer your question directly and honestly, wherever you are. That doesn't endear you to the people who took time to read your post and post an honest response.

-----

Spend some time researching the background of those Helicopter Gods who took the time to reply. Almost everyone here who posted a response has bent over backwards time and again to reply to help "newbies" (and some "oldies" ) with problems that have been posted. Most of the time, their answers are right on target, and offered freely. The majority of people who answered are pretty darn sharp fliers and pilots, and have a lot to offer not only you, but anyone else out there who needs help.
