Main Rotor Mast Install EXPERIMENTAL HELICOPTER BUILD SERIES (Part 55)

Re-Installing the Main Rotor Mast to my ultralight helicopter. In order to prepare for first Engine Run-Up Tests i removed the Main Rotor Gearbox, the Bellcranks mounting Ring Levers and the Main Rotor Control System (Inner Tube Swashplate mechanism) from the Main Rotor Mast for hardware updates.
For Re-installing the Main Rotor Mast i used Thread Locker, new Nylon Insert Safety Nuts and Safety Wire to prevent the parts from losen up in Operation.
This is the EXPERIMENTAL HELICOPTER BUILD SERIES (Part 55)
