Hi Guys,

Have a bobcat powered by a pst 1300r, have had 122 flawless flights with this turbine and never had a missed start so far.
On my 123rd flight i had a flameout at full thrust. Was lucky to make it back to the r/w. I ran her on the ground at full thrust and after 10-12 seconds she consistently flamesout. The fuel lines are absolutely bubble free when checked on the ground. No white smoke after
the flameout. This is the first time i have seen a problem with the pst otherwise we in India have around 20 psts flying and all perform flawlessly. any suggestions would be appreciated.

Thanks
Chaitanya.

Hmm, well, if there is no smoke when the turbine "flames out", then maybe it isn't a flame out. What I mean is, maybe you are overtemping on the EGT and the ECU is shutting the engine down as per the "do not exceed temperature" which the ECU is set to. I would watch the EGT value as you run it at full power to see what you are running at. If the engine shuts down consistantly when a certain EGT is reached, then I think you might find the answer to your question.

Just a thought, Hope it helps,
Brandon

Hi there, I have two of this pst 1300`s and they are very good. I think also is your EGT probe. they upgraded them , if you call Dean Wickman in Canada he will take care of you.
