Yeah, that makes sense, Minn. Now why didn't I think of that...

Just kidding, of course.
At some point, we'll have all the methods and can make an application for each installation.
The hardest part of this, because all throttles and servo's are not created equal, is finding the right method that allows full throttle from min throttle/no trim, to full throttle/full trim AND do that without causing a binding servo. Now, that's the trick to this whole thing. You want the throttle to move from end stop to end stop without actually trying to move beyond the throttle stops. That causes binds and will drain a battery very quickly. In fact, in some situations, if the bind is severe enough, you can see the servo want to twist after the servo arms reaches throttle stops.
