Predator tail set up
John I use both the Prism 7 and Eclipse for my Q500's and for both the travel functions on rudder ch4 and elevator ch2 are set at 50% . For the eclipse go to page 25 in your manual 'setting up V tail mixing' and it will walk you through it step by step. You will have no trouble getting the throws. From there you will most likely reduce throws with DR.
