i think we all fly differently as well and that also makes things different.
one thing i went through once though with a model was a Lanier Citron (a Jim Kirkland design) which i had a Super Tigre 60 mounted. the weight came in at 6.75 lbs.
it flew perfectly right out of the box until i got to be a real smart a## with low inverted passes and forgot about the yaw effect and tagged the rudder to the ground when pushing too much down elevator to gain altitude....ouch
so plane number 2 was given life from the box. same weight, same engine, but the CG ended up being 1/2 forward of the first one to get the same flight characteristics.
i mainly flew upside down back in the 70's as a typical showoff and my CG's were usually based on inverted flight.
