AG01 CNC Hall Gimbal (Hollow Shaft Version)According to some pilots feedback, we designed the AG01 Hall Gimbals HOLLOW SHAFT set. These gimbals have a hollow shaft to allow wiring for aftermarket 4mm gimbal stick ends with buttons, switches, etc. These are for particular use cases only. Unless this is required, normal AG01 CNC Hall Gimbals should be selected. *Special hollow shaft version for adding gimbals tick switches Package Includes: 1x AG01 HOLLOWSHAFT CNC Hall Gimbal (Throttle) 1x AG01
