think the best way to handle this for setup is to have a button in mission planner that sets the swash to exactly what it thinks is level. From there you should be able to adjust the subtrims to get all servo horns exactly at 90 degree's and, after this leave it in this mode to setup the linkages for the swash plate exactly.\r\n\r\nAlso, a button to set the swash to full positive and negative collective for adjusting max and min travel points of each servo, and, max and min pitch. \r\n\r\nRelying on the Tx is a PITA due to getting it exactly 0 is much more difficult than simply pushing a button."}}
