Does the front rotor have a more forward inclination angle than the rear rotor? If so how does this affect handling? I don't know if there is fore/aft cyclic for each rotor, but imagine that negative longitudinal dihedral would reduce cyclic movement in forward flight.

I'm not a Chinook-jockey - but I think, it depends, from which drive shaft you are speaking.
Engine - the helicopter has two - so normally not that a problem, except in hover.
Drive shaft between the gearboxes? That's why the Banana is also called flying coffin...
It tends to tangle the blades from front and back, when die dirve shaft goes.....
Much less chance than surviving a tailrotordriveshaftfailure in a normal helicopter....
