so Negative
I'm pretty sure he means negative as in g<zero - like free fall plus some additional negative thrust from relative wind from above the disk (at high airspeed with nose down attitude)
same problem happens when peeps talk about negative pressure ... meaning negative relative pressure. 1/2g is not -1/2g
Cyclic would need to come aft as lever is lowered just to maintain the same attitude - but it's obviously better to bias it towards nose up - so cyclic needs to come back - it's often useful to increase aircraft pitch attitude even at low lower speeds...
