I am working on a traditional helicopter with 4 servos. One servo is the HBL 880 tail servo (http://www.mksservosusa.com/product.php?productid=131). It has a central pulse width of 760us.
I am having issues using it with the pixhawk and arducopter 3.5.5. I believe my issue is that I cannot set my max, min and trim values low enough to control the full range of the servo. I am limited to a lower value of 800.
Is there any way around this? Is it possible to change the limits within mission planner to allow for lower pulse widths? Or do I need to find a new servo for this?
