I will never buy one if that is the kind of service they are going to provide. I think everyone will think twice before buying OS engine now.

After I received the engine back from Hobbico, I took some pictures of the piston, and after enlarging them and looking at them, you can plainly see that the inside of the groove is the same color as the stained piston is, meaning the groove has been there long enough for it to stain also, meaning that the theory that if something could have been inside of the engine from the factory, it would have made the damage soon after it was started for the first time. I was still able to start and fly the engine, even after I started to have the problem of it not starting unless the throttle trim was at full trim. I think I should have been given the benefit of the doubt on this one...

Also if you look at the ring where the groove goes through it, it went right over the top of the ring, leaving it to make full contact with the cylinder sleeve, and maintaining compression. The groove almost looks like it was cut by a blade, its so straight. I could very well have been running on this since the first flight 2 gallons ago.

well, I looked on the Hobbico site tonight, and it says mine had been looked at and evidently it has to have the ring replaced again for some reason, it dont say. I hope the warranty covers it this time, nothing about price except 9.99 for something... I guess Im just crap out of luck so far on the pictures and note I sent them on the stained groove. I am gonna try to call and bang my head against the wall again to see if they will reconsider the reason for the damage to my engine the first time I sent it in. This sucks.

No, if you read some of this thread, I had the piston and ring tear up 2 months ago,when the engine was only 3 weeks old, I sent it in to Hobbico for warranty work, and they turned me down, saying that I must have sucked something into the carb, and thru the engine, tearing it up. They said that if something had been in the engine from the factory, it would have gone through the engine as soon as I started it up. they repaired the engine at a substantial discount 289.00 down to 97.00, I paid it, and they sent it back to me. I mounted it into my trex600N, and I still couldnt get it to start without running the throttle trim all the way to the top, and so I sent it back to get it fixed, again. I also in the mean time, took some pictures of the piston and put them in this thread, when I was looking at the pictures I noticed that there was as much staining from the fuel I use, inside the groove left from the trash going thru the engine, as there was on the whole piston. which means, that the theory that the trash would have went thru the engine as soon as it was started is what it looks like has happened. If the groove had happened after I had burned two gallons of fuel through it, it would be shiny, not stained from running it. I sent it back in and wrote a note to them, saying I would like to rehash the issue of warranty, and they have said nothing to me, it says in the repair progress report that they are going to replace the ring, again, and thats supposed to take care of my problem. But, what about the 97.00 I had to pay to get it fixed in the first place? they are saying it is still my fault, I guess. I dont understand how its my fault if it happened when i first started it, apparently...

well, I sent in the engine the first time at the first of December, and its now the 2nd of February, and I still dont have it back and running yet. I got it back over a week ago, and it still wouldnt start without running the throttle trim all the way to the top of the trim value, which is what I sent it in for back in December. They replaced the piston, ring, rear bearing, heat sink head, sleeve, piston clips the first time, then sent it back to me, and it still ran the same as before. I sent it back to them and they had to replace the ring again, and all I did was try to start it. This is a fantastic engine OS has came out with...It now has been in the repair shop, more than it has been ran.

According to you, they have replaced all the internals...so you have a brand new engine except for the casing and the carby.

That just leaves a few possibilities.

1) There is an issue with the carby mixture
2) You have no idea how to run in an engine.

Of course the engine won't idle well...yet. It needs to run in first...build up compression while the ring/piston/liner seat themselves in.
Until such time, the engine will be a bit all over the place....mixture keeps changing....engine temp spikes etc.

You can't expect them to run in the engine for you.

Obviously, you cant read threads correctly, I just said they had to replace the ring again, so evidently it had no compression, possibly from a broken ring. just like it had been running before. what does that have to do with tuning, carby mixture, my being able to properly run in an engine??? You should really read the thread before you throw attitude around. And BTW, I think they should at least see if it will start, I said nothing about running it in for me.

I have been following the thread from the beginning, thank you
It's typical for "ringed" engine to have low to no compression until at least partially run in.
I think I am getting the idea of your "ability" to tune and diagnose engine problems, which it seems more and more likely you self-created.
According to you, they now have replaced "all internals" and for the 2nd time the ring.
Somehow it seems to constantly come back to the same denominator....."you".

Im sorry, you've lost me here, I own the engine, it has to come back to me everytime, huh? If Im the only one running the engine, wouldnt it only come back to one person, me? think about it. When I got the engine in the first place I ran almost two gallons of fuel through it, at the same trim setting. It consistently started, and ran great. Then out of no where, it wouldnt start without running the throttle trim to the top of the trim, and thats almost 1/2 throttle, just to run. How does my stupidity get involved here? I turned nothing, I touched nothing. Please explain yourself here? your stating that somehow my stupidity got involved in the running in of my engine. can you elaborate more on this assumption? when I got the engine back, I couldnt get it to start without the trim being ran to the top again, so, again, how is that something that I cant seem to do right?

I guess he means it is stupid to try to run an engine with a broken ring????????
The way I read the post is that the engine was supposed to be rebuilt to new condition but it wasn't.
I think alfred is out of touch and out of line trashing someone for something he doesn't understand.

Now I'll give you that, I should have expected something like a broken ring, coming from Hobby services, having had everything replaced in it, it really does show stupidity not tearing the whole engine down, before I started it, to see if it had another broken ring.
Alfred musta got up on the wrong side of the bed, I guess he had to go get some more insults to hit me with. Wild!!!

there's an idea huh? Your the smartest one out there in the first place, if you ask me. We all should follow suit with you, and go electric.

Hobbico sent my 55 back to me, and a note saying, and I quote, "we replaced the parts listed, the ring had some wear, and we replaced the glow plug" Now I have got to ask, with this new engine, the rear bearing lasted less than 2 gallons of fuel, and the ring that they put in 2 weeks ago, lasted 1/2 a tank of fuel, while just hovering, trying to figure out why I couldnt get it to start like it should. Is this really the engine OS thought it was going to be???

Tear it down and inspect it before you even think about running it again.. Take detailed pics.. What exactly did they replace?

well, the first time they replaced:

piston
ring
sleeve
rear bearing
heat sink head
piston clips

then they sent it back to me, and it still wouldnt start without the trim ran to the top, so I sent it back to them, and this time they replaced the glow plug and the ring again for the second time, and I assume they started it up this time and all is ok. I have already taken it apart and inspected it, all seems to be fine and all there, so I installed it in the Trex600 and I will try it out tomorrow, the weather permitting

Have you checked the carb for FOD? If it suddenly gives you trouble and carb settings haven't changed, it is likely that a small bit has gone through the fuel line and is partially blocking the carb internals somewhere. The bad parts may have been like that from the beginning and you only found them because of a carb issue. I have seen some pretty horrendous looking pistons in good running engines. As long as the ring is intact, they will generate good compression unless pieces of the ring lands are missing.
