Esp-07 PCB for picracer

Is anyone aware of an esp-07 based PCB for the pixracer esp8266 connector? The reason for an esp-07 is the external antenna connector.
Related question: can the esp8266_cts and _rts pins be used? If I make a PCB then might as well add them in…

I used one of this:
connected to a telemetry port, so is not exactly what you asked, but it works for wifi telemetry.
Anyway even with external antenna the range is no more then 70 - 80 meters.
