These are the upgraded Hall Gimbals for the Jumper T16 Radio, a perfect upgrade for smoother stick control and movement.
They come in a pack of 2 so one is for the Left side and one for the right side.
Using Hall gimbals also increase precision with stick inputs and last much longer than standard gimbals.
We also sell the T16 Pro Hall Transmitters here which have the upgraded gimbals already as standard.
