8 in 1 ESC Throttle Calibration Hub

All multirotor setups involve a speed controller (ESC) calibration to set the throttle range. Calibrating ESCs individually is time consuming. The throttle hub allows you to simultaneously calibrate the throttle range of all of your ESCs saving a great deal of time. It supports up to 8 ESCs making it ideal for a tricopter/quadcopter/hexacopter/octocopter setup - just plug the 3/4/6/8 ESC wires into the hub and the one wire from the hub to your throttle channel on the receiver. You could also use the hub if you want to control multiple servos with a single channel.
