Yes, the GT2F uses the AFHDS 2A protocol and Flysky documentation supports the FS-A3 as a compatible receiver for this surface radio family How many channels does the FS-A3 provide? The receiver provides three standard PWM channels Does the FS-A3 support telemetry? No, Flysky lists RSSI as unsupported and the receiver provides standard PWM outputs rather than telemetry or serial data functions Can the FS-A3 firmware be updated? No, Flysky lists online firmware updating as unsupported for this receiver Important Notes Use only with compatible AFHDS 2A transmitters Confirm receiver supply voltage remains within the 4.0V to 6.5V operating range The supplied Team Magic THOR GT2E-GR2E reference should not be treated as proof that every Team Magic-branded transmitter will bind with the FS-A3
