I had let mine run slowly for a bit to heat up, then advanced the throttle and tweaked the needle to break into a rich 2 cycle. Ka-pwang!
That's your problem right there. And the Prosynth argument is absolute bollocks.
My first .36 seized up at anything less then 1/2 throttle in the air during the first flights, even after a couple of preheated break in runs on the ground. That's probably why the rod failed later on too.
