In fact some people suspect that the present C.G. range might be a bit too far
forward. At forward CG there is only just enough elevator authority to round out
at minimum speed. This could be one reason for of the landing problems some
people have had.
A technique that has been suggested when at forward CG, (which implies Heavy),
is too trim full forward, so that at full aft stick the tail generates more
downforce, at a price of heavy stick load.
Part of the problem is that the tail is affected by the loss of downwash when
the flap comes into ground effect. At this point in the landing one must smarlty
move the stick back a notch otherwise the plane will temporarily land itself,
only to bounce.
