The Scout was indeed an odd helicopter. Very responsive controls, but the cockpit was a disaster - especially the heater lever being next to the HP cock (fuel valve for the uneducated). The hydraulics off were dreadful, and the engine reliability legendary for being poor. I believe the engine originally was developed for drones or short range missiles wasn't it?
And it needed a stability system for IFR, but only the Wasp had that.
Not so very fond memories of the machine, sadly.
