I re-installed a new motor and mount on my Slo Stick. (bear with me, still learning) I initially set the down thrust at 3 degrees. My coach flew it and told me I needed more DT. So cleaned up a few mistakes and re-installed motor with what turned out to be 7 degrees DT. I flew it today and it required constant up elevator to fly level (regardless of throttle). I moved battery back a bit and while it behaved better it still needed up elevator to maintain level flight. Elevator trim all the way up wasn't enough. Is my downthrust the culprit here? I read elsewhere that 5 degrees is the better number? [link=http://www.rcecho.com/Brushless-Motor/][/link]
