OS-8 work just fin on the Sport Jett (My experience only)
I even used the OS-F (4 stroke plug) in my SJ-50 awhile back and it ran fine---
I use Nelson plugs but THAT is a different story-

One could just as well use Rossi 4 or 5 plug....? Or any other medium to hot plug... no need to go out of your way to get a Merlin plug.

Yep, lots of good plugs you can use.
Jett provides the Merlin plugs as original equipment. Al makes a great product. (in fact the Merlin folks make plugs for some other folks sold under private label too).

RE: MERLIN R/C glow plug
Thanks for all the replys. I am having problems with my .45 YS side exhaust/pump motor burning up enya #3 plugs. I am assuming these are way to HOT. I am going to try the #4 or #5 plugs. Where can these be bought? Or should I just try rossi plugs?

Rossi 4 is ideal, as is the K&B HP plugs. Try those.
Merlin plus being offered by Jett are two type: Standard Merlin 2003 and the Heavy Duty 2003H.
Keep in mind, if you are blowing plugs, it is generally not because the plugs are simply failing. About 90% of the time, it is because of a lean run of some kind. Set the engine a click or two richer, make sure there is no foam in the fuel system (even the YS engines pressure system can be affected by fuel foam and air bubbles ), and try not to run the engine below 1/3 of fuel left in the tank.
A simple experiement. Fire up the engine, set the needle as normal, take off and fly around full throttle for two minutes - no more. Land. Shut down the engine. Check the glow plug. If the plug is ok, your problem is the engine going lean or drawing bubbles as the fuel level drops. If the plug is going to blow due to durability, engine heat or engine compression, it will fail relatively quickly once the engine unloads in flight.

RE: MERLIN R/C glow plug
For sure the motor is lean, It stages on the pipe real quick and revs like crazy, I am using a macs header and nitro pipe. 15% powermaster fuel. I am running a 9x9 prop. I was using a 10x7 however it loaded the motor to much and would not unload. All props are APC of course. I get only about 3 minutes and POP there goes the plug. However on the 10x7 prop they were not blowing. I have ordered some COOL rossi plugs, I hope that will lower the compression. I will also fatten up the mixture. It was spinning the 9x9 at around 15500.
Thanks for the help

[I PURCHASED MERLIN GLOW PLUGS AT THE TOLEDO SHOW BASED ON THE RECOMENDATIONS
OF THIER REP. AFTER 4 OF THE 5 PLUGS BURNED OUT IN AN AVERAGE OF 4 OR 5 FLIGHTS.
I CONTACTED MERLIN AND EXPLAINED THE PROBLEM. THEY SAID "TO LITTLE OIL CONTENT"
I ADDED 2 OZ. OF CASTER PER THIER INSTRUCTION AND MY FINAL PLUG BURNED OUT ON
THE 5TH FLIGHT. I CONTACTED MERLIN AGAIN AND THEY ASKED THAT I RETURN A BURNED OUT PLUG FOR ANALASIS. IT HAS BEEN 6 WEEKS AND THEY WILL NOT RESPOND TO MY MANY
E-MAILS. NO MORE MERLINS FOR ME!!!!!!!!!!!!

RE: MERLIN R/C glow plug
What engine are you running, and what is the aircraft ?
Jett uses the Merlin plugs as original equipment, and offers for sale the standard hot plug, and a HD version. Outstanding plugs. The main reason plugs blow is due to a lean run.
Give Al some time if you sent the plugs back. He does a pretty thorough job of looking over suspected defects.

SWORD:
I have been using the merlin plugs in SJ Jett 35, 50 and 91 and have yet to blow one. I do chuck them after a race day, but have always done that with any plug. Don't know whats going on with your experience but would change to a plug that works for you and your setups. Am not shaking my finger at your settings, just showing the other side of the scale. Oh yes, I am conserative on the needle, or at least try to be, but for the sake of the engines, not plugs. ENJOY Bro 119

RE: MERLIN R/C glow plug
my 60LX plug lasted thu break in and 8 flights before i noticed it changing color. I went to #8 and only last one flight switched back and now has 4 flights still looks good. I did pound one #8 though from being to rich on one flight. I changed props and thought it was going to unload more and it didnt.
OS does make some HD plugs which i might try to. like the R3, R5, AND THE R8
