For those interested here is another picture of an R22 with aerial spraying equipment fitted.
Whilst the payload is not huge it does allow access to small to meduim sites which may be harder to reach using ground based equipment.
The system is powered by the small engine on the RH tank and started by the loader/driver.
The throttle is placed in easy reach of the Pilot.
If I had been involved in naming it I'd have called it the 'Aerosol'!
