Rotor Balancing Jig

Many modern gyroplanes suffer from terrible stick shake, often attributed to 2/rev. Some people blades can go out of pattern. However tracking down the cause of stick shake requires accurate span wise balancing of the whole rotor. This jig was designed to facilitate this. It works off standard Skate board or fidget spinner bearings and uses small spacers for the standard bolt size. Print 2 and fit bearings and spacers inside to balance the rotors either with a digital reader or spirit level. It works.
