design Fully articulated rotor system for Scorpion Helicopter

Design Fully articulated Rotor system:-suitable for experienced Aeronautical / or Aerospace engineers or those with a high degree of mathematical and engineering skills who can understand all the requirements. Design3 0r 4 blade (prefer 4 Blade) fully articulated rotor and swash plate for 2 man Scorpion helicopter: Scorpion two helicopter can be found on the internet under that name , helicopter will have design changes with the engine and transmission, a Mazda 13b will be fitted with a two stage transmission including a sprag clutch oil circulation pump (parts from auto transmissions) engine will be turbocharged and deliver 200hp at 5000rpm The helicopter will weigh approximately the same except seats will be customised with shock resistant seating as per a similar helicopter can advise at a later date. the cockpit will be of a teardrop design, this will be part of current weight. tail rotor will be mechanically connected. would prefer Aluminium rotor blades supplied by Vortec who sells the plans for the helicopter. (see Vortec on the internet) I am including a cross section drawing of an idea that I have to make the transition of blade rotation smoother (I would like to discuss with an Aerospace aeronautical engineer) further information supplied as required or requested
