    SAB HPS 3 Bladed Main Rotor System is not cheap at $335.

    There is $70-$80 500 Four Blades Main Rotor Head assembly H50145:

    This 2011 video shows performance with scale fuselage:

    Gartt 500 kit is only $134:

    There is also combo with electronics, motor etc for $322:

    So for around $400 4 bladed 500 can be build... sure additional pair of blades is needed.

    I assume it can require some Align parts like 500 swash, main gear, umbrella gears.

    I am just impressed with performance of this scale 500 with 4 blades.

    Just the idea... is it bad?

    I like:
    - idea of more than 2 blades, I know heli with one blade can fly ; )
    - making Gartt clones flyable (vide Gartt 800)
    - low RPMs, low disc loads
    - testing cheap electronics
    - experimenting

      Includes:
      • Fully Assembled 3 Bladed Head
      • Swash
      • Swash Follower
      • Linkages
      I got whole X7 kit for around $450.

      SAB head is cheapo in comparison with Ming Da.

      It is expensive, I put my 700 in the ground hard a month ago, nothing on the head was bent or damaged except the pitch links. And it it is the three bladed head. The three blade tail has a great price on it, very affordable.
