Introducing our new patented Quarter Scale ServoBlocks™!  ServoBlocks™ increase a servo’s load-bearing capabilities by helping to isolate the lateral load from the servo spline and case. The extreme versatility of ServoBlocks™ allow users to create complex, extremely rigid, structures with ease using standard Hitec servos. The ½” aluminum hub shaft provides multiple mounting options using 6-32 screws. The robust 6061 T-6 aluminum framework acts as a servo exoskeleton, greatly enhancing the mechanical loads the servo can withstand.  ServoCity’s new .770” hub pattern is repeated throughout the framework to allow endless attachment options.  The new Quarter Scale ServoBlocks™ are compatible with the following Hitec servos: HS-755MG, HS-755HB, HS-765HB, HS-785HB. When used with a Hitec HS-785HB servo, the user can achieve 3.5 rotations without any modification. The kit ships unassembled and the servo is not included. ServoBlocks™ are a must have for any project that demands the most out of your servo! Servo not included. Patented.

Ball-bearing supported output shaft.
