This is a replacement main rotor damper set for the Align 600 and 600N line of helicopters. The dampers fit over the feathering shaft and into the main rotor housing and provide a firm but flexible support of the feathering shaft and main blades while allowing the rotor assembly to "flap" normally which reduces vibration in the rotor head assembly. Firmer dampers generally results in a more responsive feel to the helicopter while softer ones provide a more stable feel. These are the softest dampers Align offers and are best for beginners and sport flyers.
 
Package includes:
(4) Grey 70° dampers
