At the other end of the scale, I did my initial helicopter training on a "floppy stick", relatively large, (8,000lb MAUW, 53 foot rotor diameter), single engined helicopter with manual throttle reversion on its 1050 shp turbine.
It taught us how to operate a throttle on that particular type if the governor failed and how to carry out low level nav, IF, USLs and live winching. We were required to carry out EOLs solo with about 45 hours total rotary.
As far as basic aircraft handling goes, not much else that couldn't be done on any another type though.
