Detailed Description

Specifications: Application Fields: fix wing & Helicopter Battery range: LI-XX =2 ~ 4 cells; 7.2V ~14.4V NI-XX =5 ~ 12 cells; 6.0V ~ 14.4V Working Current: 25A /30 A Surge 15S PWM frequency: 8 KHz Maximum RPM: 2-pole motor / 210,000 rpm 6-pole motor / 70,000 rpm 12-pole motor / 35,000 rpm Protection: OHP, Over Heat protection OVP, Over Voltage (battery) Protection LVP, Low Voltage Protection (soft cutoff) BEC Current: 2A（Max.） Ambient Temperature: 0℃- 50℃ Weigh: 22 g Size: 40 x27 x 8(mm) Features: ●High rate 8 KHz switching (PWM); Supported highest motor speed: 210000 RPM (2 poles), 70000 RPM (6 poles), 35000 RPM (12 poles) ●Dynamic braking ensures prompt prop folding. ●Over Heat Protection.(OHP) ●User easily Programmable ESC Features by our ESC Programming Card. ●Low-voltage soft-cutoff protection, cause Throttle going slow down. ●Battery range protection, when the voltage of the battery pack is lower/higher than the Battery range threshold, the alarm status is activated. ●Brake/No Brake operation. Stop folding props cold — or let fixed props freewheel. ●Safe “power on” arming program ensures motor will not accidentally turn on. ●Low torque “soft start” prevents damage to fragile gearboxes. ●Auto shut down in 2sec after when RX signal is lost or radio interference becomes severe. ●Throttle Range can be auto setting during at first power on time. ●ESC can make brushless motor play a music when all the setting is ready to go.
