I appreciate all of the insight into this incident.
The plane began flutter when it was flying level. The only things I had attempted with the plane was level flight no maneuvers were tried.  I would assume that the problem occurred due to the speed after reading the posts on this situation.
I would not have expected the plane to experience flutter at half throttle.
I have a friend in modeling who said that flutter can happen even at low speed.
The left aileron had the control horn ripped out however I don't know if this happened during the crash or if this is what led to the flutter.
