Good catch, Bobber! The corrected figure by Gordon Mc might give a false impression of lower G load. Trying a more realistic 200mph at 300ft turn radius which gives almost 9G[&o], which is very attainable for many jet models. Also want to clarify that I'm not advocating extensive calculations or testing of kits before going to market. For a $7000 to 10k+ kits, some delligence seem not too much to ask for, besides the usual test flights. I recall seeing a picture of Peter Michel's large airliner model having to pass a static sandbag loading test. Haven't check the AMA experimental class requirements, but I'm guessing it might be there.

BTW, my simple 10-G static test was not intended as a destructive test; but just a pre maiden flight check for the simple calcs of the extensive spar carry-through redesign in converting the JHH F-4 to EDF. I can assure all it was an inexpensive & not at all time consuming excercise; although it sure gave me the warm & fuzzies. Just my 2-cents
