A nice AR636A, currently has version 2.30 firmware which has SAFE. I'll unregister it when it sells to the new owner can register and download whatever firmware you want (SAFE, or non-SAFE, etc.) via the Spektrum programmer.

Not locked, able to be programmed to suit your needs.

45 bucks, + 4.00 shipping with a tracking number in the US. I'll cover paypal fees.

Only significant issue is a bit of missing sticker on the backside - no cracks, no nicked wires, etc.
