I can see our colonial cousins are never going to be satisfied

IFMU seems to think that a pusher prop is the same as a tail rotor (which has pitch links et al and actually takes power out of the dynamic system).I would argue there is a big difference between this and an airscrew that takes power away from the rotor.

Shawn is correct in part although there are pictures of the aft facing exhausts on G-Lynx,in particular in the book " Putting the Record Straight "by Dave Gibbings ,senior Westland flight engineer at the time.He explains how the engines were boosted in power using water injection to feed the uprated transmission and how the exhausts were turned to face aft to get rid of the 600lbs of residual thrust. The importance here is that it was residual and not the prime means of forward speed.The aircraft was also fitted with additional tail fins because the tailrotor could not counteract the increased torque suppiled to the main rotor.Again evidence that the drive was predomimantly through the rotor system.
