Hi Karl, really enjoying making your cyclic and collective designs. Thank you for all the hard work you put into these projects (I've made quite a few!). They are so well designed and teaching me so much about engineering along the way!
I think I have come across a part missing in the HS mod for the cyclic. It is the HS adjustment/fixing adaptor that goes onto J3A Unijoint Body HS. I can see it in the picture you supplied but cannot find it anywhere in the files. Are you able to update the package to include this please? Hope I'm not being blind here!
