SummaryThis is an updated tail mechanism for the Trident and Switchblade 250 tricopters. This updated version is designed around a larger servo, and should accomodate a Hitec HS-65MG or similar size servo. The new tilt mechanism is also designed to use the servo horns included with the servo and requires a 10mm spacing from the servo output shaft to the mounting point. Use the small self tapping screw included with most servos to mount the horn to the tilt mechanism. This tilt mechanism also requires an M3 locknut and M3 screw to complete the pivot. The V2 Tail should accomodate the Hitec HS-65MG servo. The V3 Tail has slightly larger pocket to accomodate other servos but I am not sure on exact compatibilities.
