hK600 Shaft to short

Apr 28, 2019

The description is - This complete upgrade rotor head for your HK550 or HK600 helicopter will slot straight into your helicopter. It will not fit straight into hk600 the shaft is to short so you use the original shaft but then the arms are not long enough. I would recommend taking it apart and applying grease to bearings and thread lock to threads ect apart from that it works smooth .
ps its about time they bought out hk600 fBL helicopter

mixed feelings

The thread on the bolts adjusting the length of the string is not cut correctly !!!
The short shaft is not suitable for my HK 600 helicopter, because the lower part is shorter by 10 mm and does not fall into the lower bearing.
Dampers on trunnions are too hard because of this, there are large vibrations.
This greatly disappointed me. Although in fairness it is worth noting the excellent build quality, there is no backlash, all bolts are well screwed onto the thread retainer.
