Interestingly if you talk to *experienced* aerobatic pilots they will suggest that the crash was not caused by the overweight condition or C of G (which realistically may have made stuff-all difference), but rather the pilots inability to control the aircraft and exit the developing spin - this is of course mentioned in the report too (as in the lack of experience / training). Overloading an aircraft, putting the C of G too far rearward won't necessarily result in this outcome. Interestingly many of the RV aircraft have weight limitations due to a number of reasons such as export requirements and limitations on wing-spar's etc, so one could almost draw a conclusion that the aircraft may have been capable of safe flight at this weight. I'd like to hear more from an RV expert.
