This is an adapter which helps to convert TURNIGY/FLYSKY 9X radio control transmitter from air to surface (ground) control so it can be used on ground models like cars, trucks, on-road and off-roader.  The aim is to limit the movement of the stick to 'one directional' control per-thumb stick; up and down or left to right without accidentally mixing about with other axis by accident hence 'direction limiter' adapter which is required to drive an R/C cars.    The adapter capable of 'self-centered' the stick by adding rubber band on the mounting if the stick doesn't have centering spring normaly for planes throttling.  It works with various stick configuration MODES.  The adapter is easy to install by unscrew the top thumb stick by hand then slide in the adapter.  The adapter can be sticky tape firm in place or screw in by making a small screw hole on the top and bottom of the flat surface stick gimbal for solid foundation.  You'll need to print 2x adapter to fit 2 sides.  I designed this adapter so i can used back my TURNIGY/FLYSKY 9X radio for long range FPV driving on my off-roader because the 9X support modular radio transmitter that can be swap for long range frequency and also more channel support.
