Charlie P,
You mention end points, what are they ?????

When I'm setting up the throws I simply use a ruler which isn't neccassarily the most accurate way of measuring how much the surfavce is moving and if I want more / less just dial it into the transmitter so that up / down on both left and right are near as damn it the same or as close as I can get and then for dual rates just a % of full rates. Is there any more accurate way to do it ???????
Cheers,
Neville
