Servo Trim Question

[neiloliver]

On a Vantage II, is altering the sub trim the same as moving the mechanical trim on the transmitter? if it is, then does this alter the throw each way? I have been wondering this for some time and then heard Brian and someone discussing this today, but did not hear the outcome...

Sub-trim and handset trim are different.

Sub-trim moves the neutral of the servo and maintains even throw in each direction (within the mechanical limits of the servo of course)

Handset trim moves the neutral but the trim end points remain the same, so as you move the trim to the right, you will have less right lock to play with and vice versa.

Use sub-trim to set up the linkages on the bench, use handset trim for fine tuning on the track. You should never need more than a couple of clicks of handset trim, if you do something is awry in the chassis setup.

once you set the sub trim and the end points up, the end points move if you reset/move the sub trim settings, so do both at the same time. on the old original vantage 2 (not TypeR) the handset trim moved both the centre point and by accident the end points, thus needing the end points resetting, a flaw in the original set.
