    I recently purchased my first Nitro RC truck. The Duratrax Maximum ST Pro. I love the truck so far.

    Yesterday I burnt out two NEW glow plugs on the same tank of gas. I am unsure of the brand of the gas (borrowed from a friend) and glow plugs, but purchased them locally here in Germany. They were a #6 if that gives you any information.

    Today I replaced them with the original plug I got from Duratrax, and after two 10 minute runs, it too has burned out.

    Is there something I may be doing to blow these glow plugs prematurely. I mean three plugs in four days seems excessive to me.

    Thanks for your help.

    You could be running your car too lean. That will take out a glow plug pretty fast. Also try an OS #A5 or #A3 glow plug. They are a medium and hot range glow plug that should last a while. Make sure you use a good fuel with at least 18% lubricant and a good anti-foaming solution. If your fuel is foaming it will cause the engine to run lean. I hope that helps ya some.

    Rockn82,

    I don't know if I got the right thing or not, but my LHS gave me a OS Type F plug...it was $8.95 euro, so about $10 US dollars.

    It says on the package that it is for 4 stroke motors but I don't know anything about these Nitros...This si the only Hobby Shop I know of nearby.

    Anyway the fuels I am using is Sidewinder red at 25%.

    I ran the truck for about an hour today, until my 7 year old wrecked it pretty badly, and I had to fix it...then once I got it fixed, I broke a turnbuckle by hitting a curb....so I have to wait for the turnbuckle to get here.

    Will know more in a week or so.

    I think your 4 stroke glow plug is not designed for your 2 stroke engine.

    25% nitro is hard on the engine (just my opinion). Try 10%.

    I agree with rockn82.
