I never should have said "G" forces -
I was referring to high +/- airloads on the wing from aerobatics.
Stabilizing the ailerons during these loadings is important.
The least bit of deflection on one side, changes the next heading.
Unless the entire airframe is tested -the idea of what is a good control setup and what is a bad setup - is futile.
I do understand linkages and torsion setups -
good linkages do not twist or deflect.

Torsion bars on cars / trailing links/ etc., are another story -and a lifelong hobby of stuffing different engines in cars.
Anyway the new plane will have a rock solid rod and crank interconnection -at two point on each aileron-then crossing to the other aileron
The servo will simply position the linkage-again just like a good full scale aerobat.
I gather from a number of comments in this forum, that these craft are not familiar to many.
