Wow! As always, one of the most impressive displays of FreeCAD and technique.
Could you show what setups you use in Sketcher visibility automation (pic)?
Thank you

Re: V0.21/Assembly4--Ultralight Helicopter--Update #3
The tail rotor gearbox and associated pitch control are now complete which finishes up all the drawings with the exception of the main rotor blades which I will tackle next. My friend has since lost interest and confidence in this particular ultralight helicopter design because of all the errors we uncovered in the drawings during modeling. Neither of us are component helicopter designers. However, I've decided to keep on the project and finish up the remaining details of the assembly which I should be able to glean from the build videos mentioned in a previous post.
What follows are a few images and comments about the control mechanism that changes the blade pitch of the tail rotor:

This project is nearing completion now that all of the drawings have been checked but found wanting. That was the original objective so I have little incentive to add any further detail except at my leisure.
The following images show the last of the progress so far:
.
The only major components to be added are an air cleaner, radiator, and the fuel tank so I am tempted to call the project complete for now.
Hopefully, this project provides some encouragement if you are a new user and adequately demonstrates the basic capabilities of the PartDesign and Assembly4 workbenches. IMHO they have proven to be more than satisfactory for the mechanical design of complex engineered assemblies.
