All sound good, but it does it with power on or power off. It also pitches down with no elevator input needed. Say for instance you are flying along straigh and level and you cut the power. The nose will drop slightly when it gets slow enough. When the nose does ease down it just keeps on till it is pointed straight down. All of the contol linkages are good and strong and the servo is fine. Everthing is brand new except for the airframe which was the only thing involved in the crash. Before my CG was about 20% chord so we will try to move the CG forward a bit, but i dont think that will help as it did the same thing with the OS 40 LA on the nose. With that the CG was about 15%. That is why I kinda ruled out the CG. I am completely stumped on this one. Any more suggestions?
