Agree about plug life and running lean, though. I don't go through many plugs at all in my four strokes.

Can you honestily say that you need every single RPM you engine will produce? I doubt seriously that more than a handfull of modelers can tell the difference a couple hundred rpm makes in their engines. From what I've observed over the years (18) most modelers are lucky to know how to properly tune an engine let alone be worried over a couple hundred rpm either way. What's the point? Most models are seriously overpowered and have pilots that are underskilled and lacking in engine knowledge in the first place.

As I've said before. What those of us that have extensive experience and knowledge of engines use makes no difference. Anyone who reads this forum can decide if they want to spend $3.50 a plug or $7.00 a plug. Why are you trying so hard to defend your choice in using the $7.00 plug. I don't care what you use.

You know what? Since you have never TRIED an OS plug, you really don't know what you are talking about, do you?
It's not about top end, either. It's about idle and transition, and nine times out of ten, a four stroke will idle lower and better with the Type F, which is why people use them and rave about them. MANY times, when a four stroke will not run right, simply installing the correct plug will cure it.
Like Bill R. said, I have never seen a four stroke that did not run well on this plug.
This has nothing to do with your vaunted skill and experience...it happens to be that the engine will run right with the right plug, no more, no less. All of your "extensive experience and knowledge of engines use makes no difference"...if you have the wrong fuel or plug. Period.
Keep using your $3 miracle plug, if your mind is that closed, you don't need to know if there is something better.

Status: online 		Thanks for loosing your temper. I have no problemwith transition or idle with the plug I use. Like I said. You use what you want and so will I. Sorry I didn't know you were an expert. I just love it when you so called experts get pissy with anyone who doubts your opinion or goes against what you believe.

Status: online 		Hey everybody. Forget what I've said here. Everyone go out to your field box, throw away every glow plug that you have for your four cycle engines and run down and get some good ole OS F plugs because EASYTIGER has deemed that's what we all should use if we have a brain at all. Thank you EASYTIGER. Life will be so much easier under your guidence. None of us has to make a decision about anything anymore. Your wisdom is all we need.

Oh, would someone tell all the other plug manufacturers that it's futile to continue to make their inferior plugs. We won't be needing their services anymore. EASYTIGER has shown us the light and the way.

All praise EASYTIGER!!!

Sorry, but I must disagree, and defend ET.

All he has done is state the facts as laid out by you. If you have never used the OS "F" plug you simply are not qualified to comment on it.

You are qualified to say you're happy with the Fox "Miracle" plug. No more.

And your two responses to ET pointing out your obvious lack of qualification were childish, not up to the level of your prior posts at all.

Bill.

Status: online 		I'm happy with the plug I use and meerly point out the fact that wheather or not I use an OS plug has no bearing. He states that it's the best plug period and wheather or not that is true has no bearing on anything. Anyone who flat out says that one product in this idustry is hands down better than anything else is kidding himself. State your opinion and don't attack anyone for not sharing it is what I say. I suppose if anyone here has a strong opinion on a particular type of fuel we could generate the same type argument. There is no one right product for everyone, period. I am no the one throwing stones here. He is the one who says I don't know what I'm talking about. It's not supposed to be personal but I can go there if provoked.

Status: offline 		Sheesh. I can understand brand loyalty for expensive items to a point. One hates to admit you could have saved a few bucks buying something that costs less but works just as good. But glow plugs?

Nothing wrong with trying a few plugs out. Getting the right one will save a lot of fuel. The other ones will be used on another engine, or when I cannot find my favorite fuel, or even a spare when I am out of the right plug. Using a hot plug on a high compression engine or high nitro wastes power and fuel.

Now I have tried just about every plug except maybe the McCoy 4C, the main difference is the heat. In general a hot plug will outlast a cold plug because of the thicker element. Want a plug that is hotter than an OS-F and doesn't cost $8? Try a ThunderBolt, the latest plug I have tried. The Fox Miracle plug is slightly colder than an OS-F but not by much. It lasts about as long when used with the right nitro. The main quality difference I see is that the Fox has a lower quality plating, it will rust if left out in the rain.

I don't know how well the ThuderBolt will last, though I suspect it will last a bit less then either the OS or Fox as the element appears to be a bit smaller. Course heat range on just one plug could also be off, I have found slight differances in heat from one to another with both Fox and OS. I would rathere have a dozen plugs of differant brands than a full card of any brand.

Hot plugs have a THINNER element. They did the last time I checked anyway.

I can't believe the appetite for plugs around here! My oldest OS .70 (15 years) has had a grand total of TWO (2) plugs since new. TWO....

The first of course an OS "F"...the last being an Fox Miracle plug installed sometime maybe 9-10 years ago.

Then again...I'm not enamored by 30% nitro. My engines run fine on 10%. Always have. And they hand start...first flip. Michigan winter..NH winter...NC summer humidity...it still works good.

Status: offline 		OS F plugs, No.8 plugs and other brand name plugs are so expensive, because the average American R/C modeler is willing to pay...

Not too many years ago, many brand name plugs were cheap.
I have a 1982 MAN magazine where AHC in NY, NY advertises 10 for $6.95.

The amount of precious metals in a glow plug element is less than one milligram, 0.000035274 ounce. Platinum is about $700 an ounce. That would make the precious metal cost per plug 2.4 cents....

Platinum Iridium and Rhodium prices haven't skyrocketed.
But since OS realized that without a plug, an engine cannot run, it priced the glow plug like a "must have" item. They are "holding us by the b*@@s", so to speak.

The price of engines did not rise significantly since 20 years ago.
Most modern engines are better and more reliable than those of 20 years back.
But now we are paying $5-$8 for this two-bit item, so these engines can run.

LOL

I've thought that for a long time too. Although I am a fan of the 'F' plug for 4 strokes.

That about sums THAT up.
It's like..."My old Jemco Corsair is better than your new Top Flite one...I have not built or flown the Top Flite one, but since I have a hundred flights on my Jemco one, I know what I am talking about...."
Anyway...moving on...

I have several packs of those old AHC plugs. He sold them in little hand-stapled packs. Not sure who actually made them. They are pretty useless plugs, they burn out very fast, and have a lousy idle. I'm sure that there are a FEW engines what will run fine on them, but after a few dead sticks, I stopped trying, and they are in my big drawer full of glow plugs now, doing nothing. They were not "name brand" plugs, they were cheapies.

O.S. "Drones?" Please. All my four strokes right now are Saitos. And one Laser. I have had a few OS four bangers, liked the saitos better. Most of my two stroke glows are OS, though. Mostly the older ones. I think the FX and LA ones were a misstep, but the old FP and Max ones have never let me down.
I also swear by the 91VRDF. If you have ever had the pleasure of multiple dead sticks with a Rossi or OPS, usually ending up with a big pile of crashed jet debris, you would understand that OS makes a great product.
Anyway...it's not mindless droning...it's wanting to fly and not crash.
Nowadays, there are a LOT of nice engines out there, but for the most part, if you pick an OS, you are going to get good service.
