Glow plug life?

[TMAXX84]

had my t-maxx out today and ran a few tanks threw it and it seemed to burn up a couple glow plugs? is this normal? how long does a glow plug usually last?

A plug should last you at least a good half gallon if your engine is tuned right.

If you are running to lean it will burn out, & if you are running to rich it will foul out...and like Cupooterluvr said if it is tuned right you should get a 1/2 gallon or more out of it..
