Its a FUTABA T8FG Super radio controller, if the radio controller comes with receiver and accessories it will worth between RM$800~RM$900, but if it doesn't include complete set except only radio itself it will be worth RM$550~RM$600.

Not much people interested since in today market we can get good reliable quality R/C controller for under $300 with cool features,  maybe you can try sell it at  https://www.malaysia-rc.com/ forum but you'll need to register yourself to access buy sell threads.
