Hi
After starting my DA-100 and allowing it to warm up I adjust the idle using throttle trim. I then fly for 12 minutes. On approach to land the idle is so high a landing is impossible. Have to adjust the idle down about 6 or seven clicks to get the engine slow enough to be able to land. On the landing roll I then have to increase the trim to keep the thing running. This engine has unbelievable power. Have had over 200 flights. It's just the $%#@#$ idle that is a problem. Have tried different oils, no difference. Any one got any ideas???>.......................Ted
