BTW at 34 kgs MTOW ( 75 lbs ), this plane is under LTMA-1 regulations.

Max wing load: 100 oz/sqft
The philosophy of the AMA regarding the flight envelope is to demonstrate it by a dynamic test, as opposed to loading static tests required in Europe.
"It is important that the model aircraft is flown to the full extent of the flight envelope appropriate to the
aircraft, including full speed level flight, minimal speed level flight in a dirty configuration,
and recovery from a dive or split S maneuver."
The only static test required is made by hand:
"
The inspector shall verify that all flight surfaces (wings and tails) are reasonably stiff and solidly
attached to the fuselage. With the fuselage held in place (by hand or mechanically) the inspector
should hand load the wing from the tip, applying both vertical loads, up and down, and twisting
loads, leading edge up and down. The intent is not to determine the ultimate strength of the
model, but that under moderate loads there are no unexpected motions, and that there is no
evidence of failing joints. The tails shall be tested in the same manner."
However, given the amount of vertical play in the wing incidence system on the plane that I reviewed, I believe that it would not qualify for these requirements neither.
