Awesome pics folks, first time I've seen them, thanks.
A pusher prop would also negate the need for using more forward cyclic at full speed and keep the airframe flatter with the airflow.
Seems like autorotations could get interesting with such a configuration especially the end bit, however I guess if you had enough height you could use the windmilling effect of the pusher prop to drive the MR-RPM back up again if it got too low.
