8-in-1 ESC Throttle Calibration Hub

This 8-in-1 throttle calibration hub connects up to eight ESCs to a single receiver channel, so their throttle ranges can be calibrated together instead of one at a time. It suits tricopter, quadcopter, hexacopter and octocopter builds, and general bench work for FPV builders and RC technicians preparing a multirotor for its first flight.

Key features

• Distributes one throttle signal to up to eight ESCs from a single receiver channel.
• Calibrates the throttle range of every connected ESC in one pass instead of individually.
• Also works as a signal splitter for driving several servos from one channel.
• Useful during new builds, ESC replacement and bench testing before a maiden flight.
• Simple plug-in wiring — no soldering needed to connect the ESC signal leads.

Remove propellers before calibrating, and follow the ESC manufacturer's throttle-range procedure.
