What am I doing wrong?

Flying very low preformance gliders or flying with the spoilers open?
Neither, nor. Nearly all of these gliders have an L/D between 40 and
60.


Hmmm... is it possible that you are flying with an extremely aft CG?

If the CG were aft, then it wouldn't have a restoring force and so wouldn't
oscillate. It's when the CG is toward the forward limit that the
oscillation is worse.

Never notived that (my CG is very forward if I don't have water/lead
in the tail). The phugoid is always there, and is always (nearly)
dampened away after a number of oscillations.
