Ok, so let me get this straight. I just want to learn my radio so I know how to set up a helicopter myself.

First, I set the servo arm 90 degree to the linkage at mid stick. I setup the servos so they give me max throw in either direction without binding using the servo's endpoint on the radio.

If I run with 0 degree pitch at mid stick, the swashplate should be level and all the arms and linkage should be parallel and/or perpendicular. This is the mechanical setup.

At this point, assume I get -10 and +10 if the throttle curve is a straight line from point 1 all the way to 5. This means if I move the stick to the extremes, and I measure the pitch with a pitch gauge, I get -10, and +10.

But if I only want to have a minimum pitch of -3, I can just adjust the point 1 (or 2 if needed) on the radio so that the curve never come close to the origin (bottom of y axis, which is -10).

Then if I want more negative pitch on idle up, all I have to do is change the curve from the radio without even touching the mechanical setup.

Is that right?
