Attention giant scale modelers! This is your dream rudder servo! Our digital, steel gear HS-7956SHR  is unlike anything you’ve seen on the market. Featuring an integrated pull-pull system and wide mounting tabs measuring 1.73 x 1.54 inches (44 x 39mm), this tremendous servo eliminates the need for a separate rudder servo top case. The HS-7956SHR is equipped with a high performance coreless motor, ultra heavy-duty, ball bearing-supported metal arm and two adjustable ball link rods making it a monster performer for your 30 to 80cc giant scale aircraft. The oversized ball bearings provide strength and stability in order to eliminate any rocking motion of the output arm. For your convenience, we also developed a rudder tray conversion kit. Let this outstanding rudder servo get you flying in the right direction!
