jett
well i had a jett fire 60 that couldnt hold the rpms in the air too. ended up trashing the engine after only 12 runs. the jett service is great and it was rebuilt without question. that engine spit head bolts out every run, overheated in the air after only two minutes and barely got the DD to 100 mph. i dont judge all engines by one bad one.
