Hey Jeff,
Do you remember the endpoint reduction I had to do during our initial running of the motor so we could lower the throttle stick without killing the motor? Well, after the second flight, I had to go back and undo what I did in order to give the servo more movement so I could get the motor to shut off. I guess the motor cleared itself out a little more during the second flight...
FYI, I did not change the needle valve before the second flight. The pipe had a steady stream of smoke coming out of it throughout the whole flight and the plane was plenty quick for me. I would like to get with you again when nobody else is flying so you can do some additional fine tuning on the motor.
