I am running an OS .50 Hyper in a Trex 600 and I am using Curtis Youngblood 30% fuel. What glow plug should I be using, I am currently using OS #8, but I seem to be going through a lot of them. Is this par for the course? The engine runs strong and seems to be tuned properly.

I run the Enya 3 and it will last a long time. It really seems to pep up the punch of the motor as well.

If you're going through a lot of them then you've got a problem.
In order of likelyhood...

You're running too lean
You're shedding a rear bearing
You've got red RTV on your muffler seal thats flaking off

Examining the dead plugs will probably give you a clue. In any of the above cases you're only going to burn up different plugs if you thrown an Enya or OS 7 in there.

You're running too lean
Possibly
You're shedding a rear bearing
Not likely, I probably change them prematurely
You've got red RTV on your muffler seal thats flaking off
Nope

Do I want to go hotter (Enya 3, OS #6) or colder (Enya 6, OS# 10)? Should I richen the needle up and go with a hotter plug, or leave it and go with a colder plug?

Usually the filament burns off right where it is soldered onto the plug and I don't get any glow. It was likely flying fine before and won't start next time.

You probably are running lean pull you pipe and check your ring if its not black and is getting silver or polished looking then you are lean. But never the less the enya plug on my 50 is the best plug I run I am using the Hatori Bobby watts pipe and it likes a rich needle so the enya really shines but I also used enya's on my align pipe with better than os 8 results. Once again just my $0.02

You are using an Enya 3, correct? Do I need to richen it for that?

You understand that no matter what plug you put in, that if you're running it too hot you're going to toast the plugs?

Yes, I understand that. My question is: With a "hotter" plug, should I run richer? With a "colder" plug, should I run leaner?

Well, I got a couple replys for Enya plugs. However, no one mentioned what fuel they were using. Can I use an Enya#3 (hot plug) wiht 30% nitro? Isn't the theory to go colder with more nitro?

I'm running the Enya #3 w/ 30% cy fuel. It runs fine. Dial the needle rich and slowly lean it. If you are burning up plugs your to lean. I run the os #8 plug when Im out of the #3's. The enya's last longer.

I thought that we should use a "cooler" plug when using high nitro content fuels. The Enya 3 is Hot, the Enya 4 is Medium-Hot, the Enya 5 is Medium and the Enya 6 is Cold. I would have tried using the Enya 4 or 5 glow plug.

I have 1 Enya#3, and 7 Enya#5. I will report back when my #8s burn out and I have to replace them.

fwiw...

I have had decent luck over the years using the Enya #4 to fine tune setups....The 4 will effectively retard the ignition slightly, allowing a slightly leaner mixture/better power on some engine/ pipe/ fuel combinations. Plugs can generally last quite a while if all is well with the setup...If the element is turning a bit white, and the plug is actually burning up, I'd imagine the setup is too lean under load...

The OS8 is the standard plug for the OS hyper 50 running 30% nitro, but tuning has a lot to do with it. All 30% fuels are not the same, some do run cooler.

You could try changing fuels, and plugs, but... If you are burning out plugs prematurely. Then you probably have an issue, as stated by BaraccudaHockey.

IMO - just changing to a different plug, will just lead to burning out a different plug.

On the other hand, if you are having issues with tuning then a different plug might help.

So, to answer your question; Yes, An OS8 is par for the course for an OS Hyper 50 running 30% nitro.
