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.
