On the maiden flight of my SM 1/6 F-16, all went well, but the landing was very scary because the turbine did not come down to idle when I pulled the throttle all the way back. I estimate it was still at about 25 to 30 percent power. Fortunately it was a long runway and I have good brakes. It eventually came all the way down after I had come to a stop. Also, I have put 3 runs on the engine before the first flight, this was the fourth run.

This engine has the newer pump. Any suggestions as to why this happens, any parameter adjustments I can make?

Thanks.
