Transmitter Stick Converter

These parts do not include the small metal extension spring.  (See instructions for making/buying the spring.)
These parts in conjuction with your spring will convert the ratchet movement throttle stick for thetransmitters to be spring loaded return to the center (like the other stick movements).  Instructions show how to assemble this into the throttle gimbal for the above transmitters.  One set includes two pairs of parts, enough to modify two transmitters. (Tested and installed/working on my 424 transmitter.)
