Saturday, 2nd flight, the con-rod broke in the middle of an inverted funnel. The heli and motor has 35 flights on it and hasn't been run lean.
If I'm not mistaken, there should be a brass insert in the con-rod. If so, it is completely gone! No sign of it, not even brass shavings or dust particles.....just gone!

Well at least I have an O.S. 91 SZH pump that I can replace it with until it gets back from the warranty center.

Anyone else have this problem?

1850 in idle 1 and 1950 in idle 2. I was in idle 1 when it broke.
Main needle was set to 1-3/4 out, and the mid is at 1 + 3 clicks out.

Interesting, I guess you'll see how Align's customer service works.

I don't think you can use Hobby Services. You'll have to send it to Align or Assurance, whomever is the distributor.

Good luck,

Jeff

Well guys, here is the e-mail conversation I had with GrandRC;

Ed,
Saturday, I was flying my 700N and the motor made a clunk clunk noise then died quickly. I landed and tried to restart it, but it wouldn't turn over. So we (the guys I fly with) opened the back (crank cover)
And found the connecting rod was broken, right at the crank! So now I need to know how to get it fixed. I have 35 flights on it and have not run it lean. Outrage muffler and running 25% Wildcat fuel, with
O.S. #8 plug.

Thanks,
Ray

You'll need a new connecting rod. Do you have an experience rebuilding an engine?

Ed,

Yes, I do. I've been rebuilding engines (RC) for 25 years now. However, I am concerned with the brass insert on the connecting rod and warranty. Shouldn't I be sending this motor in for repairs??

Also, if I fix it, I'm not sure what else is damaged. I only took off the back plate.

Ed,

So if it breaks, I fix it at my cost? Manufacturing defect?

Yes, that's why it's $100 cheaper than OS (although it's made by OS)
Here are the pic's I took of the remains....

So far I will need; piston and ring, connecting rod, wrist (boss) pin, main and front bearings. Not sure what condition the crank is in, I haven't removed it yet.

That’s right Align motor has no warranty. There is no warranty card in the box, and no warranty is implied anywhere in the instructions. Just because OS offers a warranty, it dosent mean Align offers it also. Stick with OS You may pay a little bit more but at least you geat your warranty.

I recently attempted to use engine warranty for my HZ. Always call via telephone and ask ahead of time what ALL the warranty covers. When I asked, I was told it only covers a manufacturer's defect with the engine out of the box. An example is a output shaft that is really off kilter on the dial indicator right out of the box, or if the piston has a score on it right out of the box. ("right out of the box" means "new and unused" ).

The moment you use the engine and then discover something wrong AFTER the fact, there is a high chance it will not be covered under warranty. If you still send it in with a detailed letter, granting you the warranty service is contingent on their decision if they think the problem is caused by the manufacturer or not.

No matter what you say: if they disagree, you're out of luck.

Rear bearings = not under warranty.
Lean runs = not under warranty.
Piston/ring/sleeve scoring = not under warranty.
Common engine wear and tare = not under warranty.
etc, etc.

Based on what I said above, you are likely better off buying the replacement parts and working on the engine yourself. Welcome to the hobby. Before sending it in, you are allowed to take it apart for inspection yourself.

This is not to defame Hobby Services and the like. My intention is to give realistic exceptions of today's standards based on what I've learned to be true recently.

Well with that said (Sam2b), I'm screwed! I removed the crank and found a divot (small dent) in the crank pin, along with a small groove. So that means the crank is bad.

The case is chewed up inside, around the flywheel and releaved area where the connecting rod travels. The ports have metal fragments embedded, no longer smooth.

Basically, this motor is trashed. Only the head, sleeve, baskplate, and carb survived. I have read other post's having issues with the connecting rods breaking, on Align motors.

Lesson learned!

I just bought a used one off of a guy, it only has about 10 flights on it and has not been abused, but align not covering a motor reguardless of cost stinks, but again this is align for you.

^^^ it was part of the deal OS made with Align. To rebadge and sell cheaper than OS, Align had to give no warranty.

Does Grand or someone sell Align engine parts that are cheaper than stock OS parts?

Off topic, but if anything the OS owners have an advantage to buy Align engine parts at less of a cost than typical OS parts cost.

Alright.....if you as a manufacture (example, Align) are selling a rebadge motor, why isn't it stated, in print prior to purchase, that there is NO warranty??? No where on the website is it stated "sorry, no warranty!" The first clue was no warranty card or information of contact for warranty in or on the box.

Misleading the buyers isn't a good practice, or don't they care! "Oh look, stupid Americans will buy anything, they will buy our cheap crap and think they got a deal!" I suppose the Align servos don't have warranty either. 20 years (or so) ago, America wouldn't take crap like this. They would boycott the company until it cracked and gave into OUR demands!

That's why there's company's like MA, JR, Avant, Outrage, etc. Yea, you may pay more for the product, but it's backed (for the most part) with warranties!!! Not to mention, someone who just might care about their customers.

I'm sorry, just had to vent!

WOW, here's a thought; if O.S. is building engines for Align that have issues....what does that say about O.S.??? Is this what's to be expected from now on, from O.S.??

Hi guys, isn't Align and OS are from the same manufacturer? Actually what is the difference (Not comparing warranty) physically on the engine itself?

That's amazing there is no warranty and that fact should be listed on any website selling them.

Although there was a time that you could send an engine in under warranty and expect to get it back without charge I've found that recently it seems more likely you will be charged for engine repairs unless you can prove that it was a manufacturing defect.
