have you even tried a new glow plug? Nitro engines break in pretty quick...the man's will tell you different but it's possible to run them out of the box and lean to decent settings pretty quick...i've done it tons of times and never blew one doing it...whens the last time you saw someone at a track puttin around breaking in a engine before a race cause the race engine crapped out? You _should_ break them in properly but if ya didn't doesn't mean it's poofed....check the glow plug...if it's bad toss new one in...richen it out some and fire it...run it around you took some life off engine probably but I doubt it's poofed
