• Using linear design, input power: 2 cell Li-ion or Li-poly battery, features no interference to receiver. • Features power switch and voltage indicating light for battery status, to remind users to avoid over discharge the receiver¡¦s battery and out of control caused by low voltage. • For some servos such as Futaba servo models 9241, 9251, 9253, 9254, 9255, 9256 and other digital servos are not capable of handling 6V, please connect a 5.1V step-down voltage regulator to the rudder servo, or connect it between BEC (ex. RCE-B6X) and the receiver for all servos. It could avoid the servos overloading and damaged.
