R9M

• Add 16 channels with telemetry (25mW) and 16 channels without telemetry (200mW) modes.
• Improve the performance and the RSSI algorithm.
• Reduce RF power in range check mode.

Note：Please update radios(openTx v2.2.2 , FrOS v1.2.05/v1.5.05 )/RF modules(R9M-LBT-180428 ) /R9 receivers (R9/R9 SLIM -LBT-180425) at the same time to the latest or later version to get the new function or it will not work properly.

• Change the 1W gear to the power adpation gear（100mW~1W） in Non-EU mode.
• Improve the performance and the RSSI algorithm.

• Fix the bug of “Telemetry Lost” false alarm.
• Modify the PWM output period and improve the compatibility with servos.

• Optimize the performance.

• Decrease the latency.
• LED indication is the same as the XJT.
• Please simultaneously upgrade the R9 series receivers to the corresponding FCC/LBT version 180108 (or later version) before using this firmware.

• Modify the way for Bind in FCC mode.

• Optional Power：10mW/100mW/500mW/1W
