John, I will take a look at that again and verify if this is the case. The only thing that doesn't add up is that if it were a case of the servo not being far enough down in the range then the trim shouldn't work when I move it further away from the low point by 2 clicks, the way that it does........

But hey, it's worth a look.........

Right now I have the throttle pushrod in the furthest hole in the throttle arm, and Servo both. As a result I had to set the End points down at about 50% each high and low to prevent over travel. I can change the linkage around on the servo end to get the End points closer to the 100% mark.

I'll post wether or not this helps.

Thanks for your suggestion,
Rich
