RE: Rigid head on rudd/elev only?
Side tilt for the rotors is not hard to make, and gives positive control. Elevators are fine so fore & aft tilt is not necessary. Forget about lead/lag. Try a rigid (non tilting) hub if you want to but it is not something I want to do! The hubs I make are simple but do the job OK.
My hubs are shown on my website. I make my own blades too, no great problem.
