Compare to the common 2-blade rotor heads, 3-blade rotor head's hovering performance is significantly more stable. Adding one rotorblade gives your more control, and performing advance aerobatic moves becomes easier.
This metal 3-blades rotor head is for 90-class. It provides a gentle sense of control and low vibration. The rotor burden is lower.
This rotor head can be used on both 10mm and 12mm shaft by changing the collars included in the set. Swashplate and scissor arm set are also included.
According to the test results on JR GSR260Z model with K&S optional parts, you can roll and loop with this rotor head even with 6kg load.
