Upgrade Introductions:

1. Added switch option linkage gear (pay attention to gear linkage when setting throttle lock function).

2. Added English voice for flight control unlock error.

3. Added main interface 3 flight control parameter source: (When using Betaflight firmware, you need to connect to Configurator->receiver->turn on telemetry output and select CRSF protocol).

 ① CC2500: Use R16F's MAVLINK to communicate with flight control.

 ② External: The remote controller utilizes a long-range module, and the open-source receiver is connected to the flight control system.

 ③ RX CRSF: The remote controller uses V2.1 protocol, and R16F/R12F uses CRSF protocol (green LED) to connect to flight control TELEM (difference from ①: no MAVLINK on the side of the receiver is required).

4. Optimized the Japanese display and optimized the German and French factory reset interface.

5. Optimize the stick median value, with 1500 as the midpoint. Note that R16F requires an upgrade to V1.8 or above, and R12F requires an upgrade to V1.7 or above.

6. Optimize the acquisition of flight control data. When the remote control is restarted midway, it will automatically obtain data such as the latitude and longitude of the starting point.

7. Optimize the flight control parameter scrolling interface.

8. Optimize the trainer signal input, compatible with up to 16 channels.

9. Optimize the throttle ratio curve CRV graph; the throttle display value is based on the display range of the model.

10. Adjust the telemetry alarm time, adjust to 2S, 5S, 10S alarm interval

11. Fix the problem that the 5th point of the CRV curve is always 0.

12. Fix the problem that the timer countdown can only be 5 minutes.
