P-120 overspeed Flameout
I already posted this on the Jet Cat Forum but am looking for other opinions
My flying buddy maidened his Ultra Flash on Saturday with a P120 in it. He did a full run up to full power with the GSU connected and confirmed the max RPM @123K. He also did full range checks with and without the Turbine running.
Take off roll and lift off were picture perfect, he executed a turn to downwind, flew about another 800 feet and the engine just shutoff, no smoke.
Plugging the GSU in after a safe landing, he observed the Hi RPM to be 142,300. Max pump Voltage was 2.5V. Cause for shutdown was Overspeed.
A subsequent run on the ground indicated a solid 123,000.
My question is this. Is 2.5V Max pump Voltage normal on a P-120?
I'd like to hear from guys that actually check theirs after they fly.
TIA
Bob
