Turnigy MultiStar S Rev16 ESC's are the latest generation of speed controllers designed specifically for multirotors (drones). They are super simple to install and very easy to set up. These ESC's have superior performance and utilise hardware generated motor pwm for smooth throttle response. Another feature of these ESC's is Oneshot125 which is a faster communication protocol between the flight controller and the ESC on your multirotor. It allows the flight controller to send commands to the motor quicker allowing faster acceleration, regenerative braking and active freewheeling.The BLHeli S Rev 16 has masses of progamming parameters (see the list below) and can be programmed easily from your transmitter or using the MultiStar programming card. The ESC's come pre-tinned, solder ready, all you need to do is add your own selected plugs, adjust the wire lengths and solder the connections. With their small lightweight design these ESC's will have you racing faster and better without breaking the bank.Features: Small and lightweight (only 5.1g) S code for superior performance Smooth and linear control Oneshot125 for rapid throttle response Regenerative braking Active freewheeling Beacon functionality Stalled motor protection Throttle signal loss protection Safe power-on (throttle lockout) Thermal protectionProgramming Parameters: Startup power Commutation timing Demag compensation Rotation direction Beep strength Beacon strength Beacon delay Throttle range Thermal protection Low RPM power protection Brake LED controlSpecs:Constant Current: 10APeak Current: 15AInput Voltage: 2~4S (7.4~14.8V)BEC: NoneDimensions: 22 x 12mmWeight: 5.1gTurnigy
