Mechanics for Vario R22 1:4

Due to the massive modifications on a standard Vario mechanic to fit the fuselage, the idea came to design an thrue fit mechanics for this R22 fuselage kit.
The setup of the mechanics has also a driven tailrotor in case of autorotation, witch is not the case with the standard Vario mechanics.
The mechanics has a 61mm with baseframe instead of the 44mm Vario, with adds stability to the frame.
The first chapter contains the machining of the main shaft hub for the main gear.
