Thanks, this is something to consider for my next models. Indeed I have
been wondering, how critical the trim of my model was at 100% CG. It
seemed to mush slightly when in turbulence, and on the other hand, the air
in the hall was super-smooth, so I gather my trim was a bit on the extreme
side. But, cannot really test much further with that model, as I had 50mm
spacer to bring the motor forward, and the wing is at the aft of the motor
tube, so moving it further back would take the back support onto the
sub-boom, and I wonder if that is solid enough for the flight loads. So I
need to loose 100+mg on the tailplane and tailboom to get more room to
shift the CG.
