Do you have the antenna pulled out next to the plane with a fully charged battery? Don't do this... Leave the antenna down when working on the plane in the house... Pull it out when your getting ready to fly...

If you are seeing any kind of movement from the control surfaces with the plane off, the radio could be a problem. Check the plane to make sure where you antenna is routed. Also check to make sure you do not have any metal to metal contact that will rub with vibration.

Take a video and post it. We can look at the video and tell you mre about the problem. However, the best solution is to get help from a seasoned pilot from you area.
