that is a good idea. I recently moved it back just slightly and being a beginer it really got my attention as far as it flying different.

something funny about my Hangar 9 manual is that for the CG and the control movements it does not specify a range for any of these. It just tells on single figure of where they want it to be (CG, rudder, aileron, and elevator). regarding the CG is it a rule-of-thumb that it will not fly if the CG is moved behind the center of lift (which would be about the center of the wing)?
