Only lightly used in a foamy. Features Safety Arming Feature: Regardless the Throttle Stick position, the motor will not spin after battery connected. This will prevent any injury happened. Throttle Calibration: Throttle range can be configured to provide best throttling linearity, fully compatible with all market available transmitters. Programmable Items: ?Brake Settings:brake enabled brake disabled, default is brake disabled ?Battery Type:Li-xx(Li-ion or Li-poly) Ni-xx(NiMh or Nicd),default is Li-xx. ?Low Voltage Protection Mode(Cutoff Mode) ower reducing power cutoff, default is power reducing. ?Low Voltage Protection Threshold(Cutoff Threshold) :low medium high, default is medium cutoff voltage. 1) For Li-xx battery,number of battery cells are judged automatically,low medium high cutoff voltage for each cell are: 2.5V/2.75V/3.0V. For example: Cell Li-Poly, when medium cutoff voltage is set, the cutoff voltage is: 2.75 8.25V. 2) For Ni-xx battery, low medium high cutoff voltages are 60%/65%/70% of the startup voltage. For example: a 10 cells NiMH battery pack, fully charged voltage is 1.44 10 14.4V, when medium cutoff voltage is set, the cutoff voltage is 14.4 65% 9.4V? ?Star
