The reviews say they are not German, but India made. At 1199.00 I owuld think so. I paid over 3k for mine straight from Germany. Radials have only gone up in price so this lends itself to believe the reviewer.

That's not a secret Chas. It has been common knowledge for a while now that Seidel has made arrangements to have his engines manufactured by UMS Tech in India.

Quality costs money.

chasrb

Glad I got mine when I did!

I'd like to give UMS the benefit of the doubt. Mr. Seidel says that the material, tolerances, and heat treating are the same as what was made in Germany. I also remember some posts from others who had sticking valves and other such issues with the Seidels made in Germany. I'm sure Hobby King is going to sell a lot of them at that low price and over time we will know just how good they really are.

Until proven otherwise, inexpensive Seidels are something we should all be excited about!

Ditto on thet.

.UMS has more than cool engines.. they have some sweet hydrologic setups for landing gear and breaks too. the Euro ppl have nothing but good to say from them.. dont see why these engines would be any different they are mostly CNC machined parts. does it matter who works the tool? im sure enough about the quality to want one

chasrb

It's a matter of perspective, whether you bought one that was almost three times as much as the one being sold now. That is the way of commerce however and something none of us can escape. If its build is outsourced then state that, do not cover it up to make folks think it is the true orginal.

An example, my GL450 is a German car, but they clearly state it was built in the USA, in Alabama. Nothing hidden.

If these off-shored engines are as good or better, then I'd be putting two of them in my F7F instead of Saitos.

Cheers

Heard shuld be out in Sep/Aug. Quality or otherwise, seem to me pretty steep for glow. Seidel already has 70/90 cc class for 1k+. Would like to see how many oS sells.

Maybe more than you think....... this hobby is funny. There are OS fanatics, DA fanatics, Futaba fanatics......... and on.......... and on. The debates never end and no one company ever competely dominates the market. Perhaps OS plans to fill the nitch in the market reserved for those who want to pay through the nose so that they can feel like they have a superior product.

wheels

I didn't get an answer to my last question so I'm not holding my breath here but............................. on another topic...

Has anyone tried a smoke system on a saito with an exhaust ring? Does it work ok or just blow a bunch of half burnt oil into your fuel tank through the pressure tap?

kochj

I would hook it up the way the manual shows you...
Do it the same way you would on a single 4-stroke...
When I ran my saito 325 I just folllowed the manual (nice think about Saitos) and it ran great....

kochj

I found it funny to hear that the quality was what comes out the other end of a cows butt.

Seriously, though...I had purchased one....but I couldn't see leaving my full payment to them for 3-months just to
save 100$ on shipping??? It runs fine in the online vids, but only time will tell how they hold up....

I though that saydel, said that no way in Heff, that hobby tronics would sell UMS engines?

kochj

What if all the workers were PO'ed when they made these engines with all the conflict surronding
the deal with HObbytronic, and they goofed them up...?

wheels

Thanks for the response kochj, I appretiate it. Maybe I missed some instructions on the keleo packaging? The literature I have from saito doesn't say anything about an exhaust ring?

At any rate, I contacted Kelvin and he assures me that there will be no problem.

Wheels,
No offence intended, but from my engineering perspective, the only area in which Indian / Chinese engines are the equal of Japanese, Euro or maybe US engines is in the General Arrangement Drawing! As far as manufacturing processes, precision and metallurgy are concerned, there is simply no comparison.

I own ASP, Evolution, FPE and Saito engines. I could bore you with a couple of pages of technical comparisons, but you can hear the air hissing past the exhaust valve and feel the slack fit of a crankshaft bearing in my new ASP. After only 9 months flying nearly every Sunday, you can now hear the big end rattle of the Evo 46 as it flies past on part throttle. Etc, etc...

If you want to manufacture a precision item in quantities you don't throw more people at it. You throw money, in the form of top-end machine tools, production gauges and measuring equipment. Not just just little gold "QC" stickers...

As you say, there are OS, DA, Futaba fanatics, but no mention of ASP, Turnigy, or UMS fanatics. I don't think OS and Saito have survived this long just on snob appeal as there have always been cheaper engines in the market. This situation is not unique to small IC engines, and whether it's cars, computers or tools, you usually get what you pay for. Trouble is, 2x quality = 3x price !!

Regards, radial1951.

First, sweeping statements about the quality of materials and manufacturing from any part of the world are at best temporarily accurate and at worst propaganda. As proof take the fact that you hold up Japanese manufacturing as one of the measuring sticks.

Second, I`m sorry to hear that you`ve had bad experiences with some of your engines. Unfortunatley, as you know, the fact that you have in hand bad examples of a certain brand of engine means little to nothing about the quality of those engines in general. No matter what manufacturer you care to name, there ARE duds that come out of their factories. It just so happens I'm an engineer too. I own Evolution GMS and FPE engines, all of wich have been very reliable and performed extremely well for me, but that doesn't mean everyone will have the same results or even that most will, it just means I did.

Lastly, nope no Hobby King fanatics, they are a distributor not a manufacturer so there's nothing to be fanatical about. However given some time there will, without a doubt, be people who are ridiculously loyal to some of their product lines. I'm sure you can remember when HITEC was an unproven and suspect company, but do they have a group of customers who now don't even bother to look at other brands before purchasing radio equipment? You bet, I'm one of them.

I wasn't kidding about being an engineer, if you have some real, objective test data about some of these Chinese/Indian hobby products, lay it on me. It won't bore me a bit.

Hey Wheels, did you use the motor box as provided? I find that mine is way over board on down thrust and side thrust angles-I`m going to make to an angled plate to negate the d-thrust and s-thrust-It was pointed out to me by someone that this type of hi angled mount would be mainly used for electric power.

The engineering and metallurgy bickering should be done via Private Messaging.

wheels

I used it as is, although it seemed like a lot to me too. We'll see how it flies, then add spacers if I have to.

More side and negative thrust for electrics? That's a new one to me, but I still only own two electrics so I have lots to learn.

Wulf

My Feedback: (5)

I just heard this recently(more s-d thrust for electrics-) I have no electrics so what do I know LOL!I changed my engine box to square-that is no down-or side thrust then `ill add shims if needed-Seems way outta line the way it came.I epoxied a 1/4" ply plate to front then milled off square-I like it better and engine is much easier to line up with center of cowl-I`ll let you know how mine flies also-Probably have to kick on some right rudder on takeoff- :-)

Godflesh

Don't see why it should. If ppl have fair points and good info it should be discussed on the forum. I wouldn't simply dismiss such discussions as bickering.

Was on HK and they had seidel 70 listed as 5 in stock ordered and day later received an email that it is being shipped! Fingers crossed!!!
Now to find a good warbird to put it into, any sugestions?

Hello everyone, curious to know what glow plugs are being used on saito radials???

yuppp!!!


the CMP 50cc zero. I already know it will fit.. because im wanting one in mine
