Wouldn't know for sure!
I heard this from low-time guy who got the chance to play with one for a couple of minutes.
The owner supposedly told him no hydraulics and it feels very heavy in a hover!?!??
Could there be various different models, like the Bell-47 family, which has everything from no hyd. to full hyd., with models that have cyclic hyd. only....
I will check myself next time I see it...
HOwever it is definitely Ex-Bundesgrenzschutz, lots of German Markings and Instruments...
