I haven't tried what happens to each aircraft when the bug is fixed,
but my guess is that the bug only is relevant to the propulsion of the
model,
because the property "aero/coefficient/CDde" doesn't rotate the aircraft,
it only
slows it down.
All the bug does is, instead of slowing the model down, it reacts like a
little
boost rocket which magically accelerates the plane as soon as you pull back
the yoke.
During takeoff-roll the elevator deflection is almost zero, so the bug
doesn't
contribute to reaching Vr anyway.
When the bug really is needed to rotate the aircraft, then perhaps
increasing the
elevator's area or angle, or increasing engine power, or checking the
center of gravity is what's really needed here.
But I'm only guessing! I haven't verified this, I'm sure you know how to do
your
maintenance job!
