Turnigy 9XR PRO 24-Channel Programmable Radio Transmitter

The Turnigy 9XR PRO is a programmable computer radio running the ARM version of the open-source er9x firmware, with a JR-style module bay at the back. It ships without an RF module, so you add the JR-format transmitter module for the link you fly, and it suits pilots who run fixed wings, helicopters and multirotors from one handset and want deep, hands-on mixing.

Budget for an RF module and a transmitter battery that fits the 112 x 44 x 27 mm compartment, as neither is in the box. Telemetry appears on screen only when the module and receiver you pair with it pass data back.
