Introduction: The SB-IAS Air speed sensor is a small device that connects to the SBUS2 connector of a Futaba receiver or to the EX Bus connector of a Jeti receiver.

This allows you to get the instantaneous air speed (and distance travelled on Jeti) of your model airplane shown on your transmitter and/or to have the current speed announced to you from the transmitter’s speaker or earplug.

This will help you during landing phase and other critical maneuvers.
