I heared that CPLR was going to use Mine Didn't Start engines at the the next World Champs.
But then again I lie alot!

I have seen lots of people here bash OS engines but the pilots that I know of LOVE them.

Well, there's your answer.

One should just set the record straight first though.
It isn't a lot of people knocking OS... It's the SAME very small group people, constantly jumping on every thread, at every opportunity, with the same old gripes!
9 times out of 10, these people just gang-up and take over the entire thread.
It's like they're on a mission... being payed to do it.
Very annoying.

As you've stated , 99% of everyone out seem to have no problems with OS at all.

I have about 10 o.s engines. I tried a magnum 91 and did not like it to hard to set up. the os46ax at perth r/c model and hbby's are $ 145.00 and I think they have gone down a bit for the price they are great. never hear of the plating coming adrift though. butt every one have ther fav brandsmine is os for reliability and price

No doubt about it that OS is a class act right out of the box.

However, with enough running/break-in time on the Magnum, it will acquire many of the good running habits of the OS. If time is more important than money, buy the OS. If you're a retired old goat like me and you like tinkering with engines anyway, the Magnum can be a good buy. Truthfully, by the time you get done putting fuel through the Magnum for extra break-in running, the price difference has narrowed considerably between it and the OS. I still buy Magnums because I like breaking-in engines, if that makes any sense.

One thing we must keep in mind is that eventually Sanye' will figure out how to bestow OS's marvelous out-of-the-box running characteristics upon their engine products. We have to keep our eyes open to realize that it has happened already - when it happens.

OS and folks were always a class act. I hope they continue to lead the way in making great sport engines in the future. Conversely, I wish Sanye the same success.

OS got their due, their first engines were copies of Fox and other US manufactures. I don't know why they wouldn't get away with it as they broke no copyrights or patents. But didn't so much as copy the OS engines, as they hired the OS chief engineer. Though this may have been latter. The TT .46 Pro has more in common with the OS SF series than FX, but some of the other TT Pro engines are more similar to FX series. Their two - four stroke engines are unique and not a copy of anything other than the OS style camshaft.

You mean like the way OS payed Hanno to fly their engine and more or less copy the ST engine he was using, and put his name one it? How bout the way OS users used to bash eveything in sight? The bashing was one of the reasons I quite buying them in the 70's. ST was my main brand then.

I was always to bone/bull headed to pay attention to what other sport flyers were saying. If they flew a lot, tinkered very little, then I listened. On the other hand, if they showed up with a mass of tools, always had a frown on their face when it was their turn to fly and muttered profanities to themselves during the "fixing" process, I pretty much just nodded my head in agreement and thought of something else while they talked.

While I can feel really warm and fuzzy about a line of engines that has done me well, with me it can be with more than one engine line at a time.

I loved Fox engines because of my control line experience with them. In the Sixties, aspiring control line stunt pilots usually flew McCoy .35 engines, but deep inside, they wanted a Fox .35 Stunt. I managed to get my hands on a Fox .15X in 1962 and learned to fly inverted with it. After that it was a K&B .19 that my parents bought me for Christmas. Then I went big time and bought a McCoy .35. I was king of the block in those days with big iron like a .35.

I have had lots of fun with many, many brands of engines. The only ones that I really didn't like were the Wen-Mac engines before the Mk. IV. I spent so much time trying to start them, even with the spring starter, that my fingers used to get really sore and sort of kill the fun. With the Mk. IV, I could flip start them without using the spring starter. What did they change? I don't know. They looked the same as the previous engines to this kid. But they sure ran differently.

I used to fly a Fox .09 for a while, when I was really young. It was given to me because folks said that the glow heads (proprietary) were expensive. The guy that gave it to me had parents that owned the local hobbyshop. Why would he care if it went through glow plugs? Beats me. Anyway, by that time I figured out why it went through plugs when he ran it. He always peaked it out for every last rpm and, as the tank of fuel was burned down, the engine went leaner and leaner until the glow plug gave up the ghost. I flew that engine for over a year and a half without having to replace it. I ended up trading the engine off for something else. The same glow plug was still working when it left my house.

The idea that OS Engines copied Fox engines is a hilarious joke. OS was producing
quality engines in 1936.

http://www.osengines.com/history/ostimeline01.html

Fox didn't start producing engines until 12 years later, and most of his stuff was amateur
junk....that's a fact.

http://www.foxmanufacturing.com/index.php?main_page=about_us

If you look at the types of engines that OS made before Duke Fox cast his first little
sand cast piece of junk in his garage, OS was light years ahead of Fox.

The engines that Thunder Tiger copied from OS Engines were exact copies of
the OS Engines....the only difference was, the T.T. engines were of such poor quality
that in most cases you couldn't even tighten the screws without stripping out the crummy
metal from the engine cases....and that's a fact.

FBD.

Dave,
Fox was the best engines made for over a decade. The OS .35S control line is a partial copy of the Fox Stunt .35. Yet some still prefered the Fox. OS started by copying the Brown ignition engine (who didn't). Enya which started later were actually closer copies. Fox still makes fine engines.

BTW that piece of junk was one of the first all glow engines made. Lots of engine makers copied much of that work. Nothing wrong with that as their were no patents. Quality sand cast parts are as good as die cast parts. And Fox also made some of the fastest racing engines of its day. The only problem with Fox is some of there carbs are below par. Also he tended to make engines with parts as hard as diamonds and built a bit tight, so they were a bear to break in.

Fact is there is no reason a new company starting should not copy another. Smart thing to do.

Never saw the first TT engines, but many of the GP engines are copies of FP engines. I never said they didn't and see no reason to avoid that brand. Also cannot say anything about the quality of their first engines, but see no reason that should stop someone from buying thier engines, especially since (with exception of a model or two) they are superior to OS.

They never seem to have a "bad run" of engines at OS. You know you're going to get a good one, every time. How much money that is worth depends on how you value your time and your money.

Can you show some evidence of this? I'm not trying to start something, rather I am genuinely interested.

Incidentally - although this may be a can of worms we don't want to open - why is that most modellers have no problem buying copies of Japanese products, but when a US product is cloned, a lynch mob is formed? I have observed this quite a few times on forums over the years.

Flip, the only time a same sized Saito burns more fuel than any other brand is when the LowSpeed needle is poorly set

You can do a simple test at home. Time both an OS 4-stroke and a Saito 4-stroke on the same prop and fuel at full throttle using a stopwatch. My OS .91 can run a full 20 minutes on a 14-oz tank using 15% fuel shortly after the initial break in. I doubt that the Saito .91 can accomplish the same feat.
