I loosened the allen screw on the blue collar and turned the screw but it didn't seem to make any difference,i set it back to it's original place.I overlooked something,the screw on the servo might of slipped but i can change the idle that way,the engine is running too fast to adjust the low speed but with the tx i can slow it down enough to almost count each point on the prop,well not that slow but it runs pretty smooth,i can still kill the engine that way.
Thanks

* no way am i gonna turn that screw unless i know what it does*
