first off i want to say thanks for everyone’s input...
i own a nova max 5port first generation that was
purchased last year. It has about 6 gallons though it
and up to now is still running strong.

a friend of mine has the new gen nova max 3 port
w/ microcast piston is already experiencing lost of
compression. this is a engine with less than a gallon
of nitro. i'm still not positive if it's the pistons or the
hot weather we are experiencing her in so cal.
