Feature Request: Add Goosky protocol support (e.g. S2 Max) to Multi-Protocol

Background:
The Goosky S2 Max RC helicopter uses a proprietary 2.4GHz protocol. However, it offers optional S-FHSS compatibility for control only – telemetry is exclusive to the Goosky protocol. Many users would like to control this model (and possibly receive telemetry) using Multiprotocol modules (e.g. iRX4 Lite, 4-in-1).

Why is this interesting:

• The Goosky FC appears to use a CC2500-compatible chip.
• Their protocol seems to share traits with S-FHSS.
• Telemetry (battery voltage, RPM, etc.) is available when used with the official ST8 transmitter.
• It would be helpful to reverse-engineer and implement the native Goosky protocol to allow full support from Multi-Protocol-based radios.

Request:

• Has anyone already looked into sniffing or decoding Goosky protocol traffic?
• Is anyone interested in contributing to a new Goosky protocol implementation?
• Would it make sense to fork/mod the existing Futaba_SFHSS module as a base?

Test Hardware available:

• Goosky S2 Max (soon)
• iRX4 Lite module
• ETHOS transmitter

The community would greatly benefit!

Thanks!
