Please check with your track for compatibility as this works on most decoder boxes. If you ask the firmware version on your clubs box and they say 4.5 it will not work on their system. Ask your race director if an amb 3 ear transponder will work prior to buying. All sales are final.

The transponder works but I am listing it as for parts not working due to the nature of the hobby and the above statement regarding your rc tracks decoder box and firmware version. Thanks! Awesome number ending in 333
