Hello, I am curious has anyone been having any problems with warranty issues dealing with Hobby Sevices? Let tell you a quick story, I just bought brand new O.S 105 HZR and muffler combo 2 and a half weeks ago almost $800.00 I spent, that being said I installed it , I wanted to use 30% nitro , so I put the extra head shim in, went to break it in and it starts fine and idles fine but when I would spool it up to about half stick it would stall, no matter what setting I used. So I called hobby services the same day and they told me that the 105 was designed for 15% nitro, so I thought , well ok I guess I will try that with allot of reservations . I took out the extra head I put in and reinstalled motor fueled it up and same thing ,stall stall stall. So now I know something is not rite with this motor. So that same day this past Sunday I boxed it back up and sent it in to Hobby Services. Today I get an email from them stating that the bearings were rough and that there was rust on them and that there was debri in carb and there were scratches on on sleeve. At the end of invoice they are trying to charge me $90.00 to fix it. So I called them and let me tell u customer service sucked, so they tell me they have to look at motor again and they will let me know by email.....I am sick over this

The same happended with me and my 55hzr. they said it had rust on the bearings(there was none just residue from fuel) Hobby services rarely will warrant os motors known fact. I would take it too ircha and go straight to the OS tent and make them fix what ever problem your having especailly with hobby services

That's a shame. I love O.S. motors but I do believe that their back up service leaves a bit to be desired from what I've seen. Not that I'm saying they should just poof and fix everything for free but maybe lower their repair prices or honor at least some things. I can't see how you'd have rust all over the bearings after only getting it 2.5 weeks ago unless you took it apart and sat it out in your yard in the rain.

The latest is they were suppose to call me or email, didn't receive any calls or email so I just called them a few minutes ago and they said it is under review and it would take a couple of days and they would give me an answer. So I have a brand new Whiplash all ready to go with no motor, I am really sick to my stomach

yep, same old song and dance from OS re: warranty service through Hobby services.

They will pull out every excuse NOT to warranty it. Good luck in getting it fixed.

Hobby Service's poor customer service is one reason I am reluctant and have to think hard before buying anything made by OS and Futaba. I can get around the OS part by buying YS instead. I tried going the Spektrum route for radio and still prefer Futaba for radio and servos.

How can a service company that is looked upon so negatively by most in the hobby continue to hold the service contract for OS and Futaba? It doesn't seem right or smart on the part of OS and Futaba!

Sad to say, but you're going to find this kind of thing with any kind of engine warranty/support. Remember: just like any other engine shop, they've been ripped off at least 85,000 times before you've sent your engine to them - so naturally they're going to be really super careful from then on.

They've seen so many lean runs, DIY modifications and fixes and engines run on homemade fuel with white gas, gasoline, Jack Daniels and olive oil in them that they're going to be skeptical of any marks they see inside the thing that aren't normal wear and tear.

That bites, but that's kind of how it is, especially where the engine block is concerned.

Accessories like carbs are a lot less susceptible to user error and general abuse, or at least it's a lot easier for them to diagnose. So they're going to be more forgiving there.

For instance, HS replaced both of the regulators on my 91HZ-R's no questions asked when they developed problems. And one of them came to me with _no diaphragm in it_. They put in a new one FOC and sent it back to me.

But when you send them a block with even the slightest scratch on the inside.... just get ready, it's not going to be an easy sell, and it's pretty easy to see why....

YS parts and service tend to error on the side of believing the client. Hobby services tends to look for anything to deny. Don't believe me? Take a poll here. I've dealt with them and the half wit tech on the phone, had to talk with the supervisor and after refutting all of their bs excuses they finally agreed to fix a motor for a friend.

OS motors rock. I'm sure Hobbyservices has been scammed etc... That doesn't relieve them of responsibility of fixing motors. Lean runs can be caused by more than user error. Bearings with a mircoscopic bit of rust do not cause the pleathora of issues that HS imagines. After run oil is not the pancea of motor ills.

Bottom line is, when I buy an OS motor, I'm basically giving up any warranty work I may need b/c I know that short of something wrong with a NEW never run motor, they will probably deny any claim I or my friends make. I'm sure that is an extreme view of their "service", but my experience bears that out.

I could understand if I had motor for past few months and had a lot of flights on it, and there was debri in carb and scratches on sleeve , my fault ,maybe, but I sent them the credit card receipt and receipt from hobby shop that showed I had bought it a week earlier, to say the bearings look rough and rust on them is nuts. I can't justify spending another almost 100 bucks on something that i never even got to use. Oh and still no word yet from them

Great Planes in general is a crap company to deal with. They are pretty much a distributor for everything now. Their mapped pricing is a joke.

FYI I recommend anyone who send a motor into HS take very good pics of the internals of the motor. We did prior to sending my friends motor in. They stated rust as an excuse. Plus some other bs issues. When I relayed to the manager that I had macro pics of the sleeve, bearing etc... they finally backed down. I had diagnosed the problem of the motor(bad pump). Their techs and supervisor lied to me and said they never had problems with OS pumps before, I started laughing so hard at him as that is so not true and told him I could have a dozen threads on this, and the complaints about HS within 30 minuts. That finally won the case for us, but it's BS they make it such a hassle.

Don't feel too bad - the motor on my plank costs 20 large new but the warranty isn't worth the paper it's written on (Rotax). I've not yet heard a good experience from any one else either. So it could be a lot worse.

As for corrosion in a new engine, I've seen that more than once also. Just because you bought it "new", doesn't mean it didn't sit on the vendor's shelf in 100F heat at 90% humidity for the last year and a half. I had an OS 140RX on a plank years ago that was basically trashed new out of the box from Tower. I'm pretty sure it was because the one they sold me was "NOS". It happens.

So yeah if you start getting the black goo in the exhaust on a new engine, it very well could already be rusted out.

I agree it's a good idea to do some exploration on the innards before sending it in. Give them as little as possible to blame you with

Thanks for the answer.

Surely you had the needles plenty open, one way valve in place, and good tanks and fuel lines with zero leaks, which are normally the signs of engine boging from inproper fuel pressure.

The regulator diaphragm or sonething inside could be defective and contribute to the issue. The 30% vs 15% issue is BS. The engine will run on a dry martini if everything is working properly.

These engines are not complicated.
I hope a "competent" tech at HS figures out the problem.

good luck

The latest is I talked to them on this past Monday and they said that the piston sleeve is back ordered until late July I said that figures so I ended up ordering new motor and this one runs wicked, so now I will have a extra motor just in case new one breaks...

A different experience
Read this thread a couple of times before and since it has not died I figured I would relate my experiences with Hobby Services.

In short they have done me a great service on multiple occasions. Anyone ever remember the first .91 pumped O.S. heli engine? I had no luck with this motor, could not ever get it running consistently or well. I sent it to Hobby Services and explained my concerns. They exchanged my motor for a newer, more expensive model that most everyone else agreed had the bugs worked out. I also had trouble with an OS .55 heli engine that broke a crank shaft. I sent it in and got great service, they replaced the crank, rod, piston and liner at no charge. I had the old .60 worlds heli engine that went lean (my fault) and burned up. HS fixed this engine for the price of the parts and no labor.

All in all they have stood by the OS product for me, taken care of me as an RC enthusiast and kept me loyal to OS through and through. I know every situation is different, but clearly I've seen proof on multiple occasions that they provide great service.

For what it's worth....
