The way I see it is good enough for practice plane. It seems to put me more at ease learning the new maneuvers with a cheaper plane and equipment like a Turnigy speed controller with E. flight motor. In my composite airframes I used in-runners and Castle speed controller's so far the low-cost equipment I've been using for practice planes has been money well spent. Knock on wood. I must say though I'm quite impressed with my Turnigy speed controller as I have pushed it quite hard and it's still going strong. So I guess if you're willing to take the chance is a very good price. Jim
