One of the biggest complaints about the Taranis X9D Plus is the low quality gimbals. FrSky has provided the long asked for official upgrade with the new M9 gimbal. This high quality upgrade uses a Hall sensor and 4 ball bearings to provide a high quality gimbal for the popular transmitter.
The gimbals have adjustable tension and can be configured to enable/disable self centering on both axis'. A ratcheting feel can be enabled on the Y axis for the throttle input. These gimbals are rumored to be much better than the Aurora 9 gimbal upgrade.
