Product Description:·Futaba 3156, Align 410M, HD2216, MD933 TowerPro 9g, Universal Servo Arms 3156;
·The original servo arms for the 410M and 415M gears are too sturdy, making it very easy for the gears to be damaged in a crash—even metal gears are not immune to this. Furthermore, the gears for these two servos are expensive, especially the 3156, which is difficult to source!
·This modified control arm features mounting holes specifically designed for helicopters. It will not deform during normal flight but will snap off instantly in the event of a crash, dissipating the impact energy and protecting the metal components of the rotor head and the servo gears.
Packing List: Universal Servo Arms ×10
