Hi,
has anyone had a look at the Multiplex M-LINK protocol (
www.multiplex-rc.de/en/
) ?
It is a FHSS protocol using the same RF chip as DEVO (CYRF6936). It seems to be a quite common system around here for planes, but I'm not sure how far it is known outside Germany.
Additional to Transmitters there are TX modules available. My TX module integrates a CC2591 (from TI) as a RF frontend (AMP+LNA) and a ATMEGA324AP controller around the CYRF6936.
A wide range of Telemetry equipment is available. But RX's are usually a bit more expensive than Spectrum RX's.
