This is the Futaba R617FS 2.4GHz FASST 7-Channel aircraft receiver that is suitable for park flyers all the way through to giant scale models. It is a high sensitivity receiver that weighs only 7g without case yet it is a full range system.
A simple binding process that does not involve binding plugs to mess with or lose and dual antenna diversity allows the 2.4Ghz FASST Futaba transmitter to select the best reception between the two antennas with no signal loss. Rubber grommets are installed where the antennas exit to reduce stress and fraying on the two antenna wires.
