I found out why the K T 120 shut down on the runway. This is my first jet engine and I am still learning about jet engines, that being said, the problem was I did not have the throttle trim all the way up as high as it would go and that caused the shut down. I made a call to Barry at K T and he was able to help me find out why the engine shut down, I must say K T has great tech support. I have had a lot of flights after finding out why I had the shut down and I have no problems with the engine after calling Barry.
Thanks Barry
