Firmware Update<\/h3>\n\n\n\n

SRXL2 receiver protocol and telemetry support was added to OFS3 Flight controller since firmware version 14.70.<\/p>\n\n\n\n

Please download the latest OFS3 Firmware from OMPHobby.com<\/a>. Update the OFS3 Flight controller firmware using the OMPHobby OFS3 Bluetooth Module<\/a> and the OMPHobby App on iOS\/Android.<\/p>\n\n\n\n

Compatible Receivers<\/h3>\n\n\n\n

Although any SRXL2 receiver will work a small and lightweight receiver is preferable for the M2 V3 Helicopter.<\/p>\n\n\n\n

The SPM4650C<\/a> et SPM4651T<\/a> are the best options.<\/p>\n\n\n\n

Connecting to the OFS3 Controller<\/h3>\n\n\n\n

The SRXL2 receiver needs to be connected to the CRSF port on the OFS3 controller. The connector that comes with the receivers is not suitable for connecting to the CRSF port. The Spektrum SRXL2 to OMP M2 V3 OFS3 receiver connection cable<\/a> will be required. It connects to SRXL2 port on the receiver side and the CRSF port on the OFS3 Controller.<\/p>\n\n\n\n
