Aircraft Aluminum Enclosure - CNC crafted from one solid rod of 6061 T6 aluminum, mirror polished and anodized for ultimate durability Self Lubricating Slider - All new slider material reduces friction and wear prolonging the life of parts; virtually maintenance free Ball Bearing Slider Stabilization - Ensures accurate glide of the slider while reducing friction and noise delivering a smooth performance with no axial play. Adjustable Stroke - Change the stroke from 2.8-4.2mm (with variable options in between) without the need for interchangeable parts. Variable Give On-the-fly -Variable On-the-Fly Micro Dialed Give Adjustment. One full turn of the Dial takes you from no give to full give. (Only available on Spektra Edge X) Hex Drive Mechanism - Patent pending hex drive mechanism allows the motor to be detached while canceling axial load on the shaft.
