A hook carries its name justly. The full size hook can carry real heavy loads. They are used as wood carriers in remote mountain regions, for example.
Helicopter Service Wasserthal, whose helicopters belong to the polar research team and operate from the ship FS Polarstern, is able to lift up to 800 kg on the hook.
On your model you mount the hook in the required location, and release dummy loads by activating a servo via your transmitter.
Hook, 50 mm long, incl. fittings.
