Just received a full CNC head upgrade for the head (HBK2).
Found these excellent instructions here: http://www.heliguy.com/Forum/cnc-head-upgrade-photo-guide-t26784.html
A couple of pages down there's a mentioning of a "retaining pin". I guess this should have been included in the upgrade - but I dont have one?!
To be exact what I am talking about, it's image number 35 (or easier, search the page for "retaining pin" and you'll se exactly what I mean). It's a pin that goes into the main shaft to fix the head to it. The original (plastic) head does not have such a pin, instead the head is fixed with a screw. Did they fail to send me one?
Thanks for any clarification! //korven
