I have a BME 110 which on the whole I like well so far.The engine has about 60 flights so it is still relatively new. My problem is with idle speed. Sometimes the idle sped will not come down even though I have lowered the throttle to were it usually has a nice low idle. The linkage is very good with digital servo for throttle so the problem is not with position of the throttle plate. It does not always do this but when it does the idle stays up high enough to preclude landing. I have installed an optical kill switch to deal with this problem but would really like to find out what is causing it. Do any of you BME 110 owners have this problem and if so what have you done about it? Thanks Dave.
