Checked with Tim on the RC Model Autogyro facebook site & only printed parts are available from a couple members, but not the files.
Now I hesitate to ask this, as it appears my question got me banned on that facebook group...??!!
If I draw up some parts based on your plans, is it ok if I share them on Thingiverse? I have found the rotor head & rotorblades by Emanuel_Stassar, and I would like to design the nose & tail as well and make them compatible with CF square tubing instead of spruce.
