Got the blades today and they work (worked) great. Changed out bad servo, but still an issue somewhere. Almost trimmed to hands off hover and then WHAM! she goes hard right and nothing will change attitude or speed , like the TX quits working(not a battery issue). Did this 2-3 times b4 2 blades bit it....so I got maybe 3 min on this set of blades that I waited 2 weeks for, only ordered 1 set to see if they worked.......
