(4)Demodulation type: frequency demodulation
It is the very high power delivered by these small and very robust, but light weight (39g) brushless motors with rotating case suitable for all models of 300-400 size . As a result of using the latest ferromagnetic materials the EMAX CF2822/CF2212 motors offer extremely high efficiency and high load capability for their weight. EMAX motors with the high quality of manufacturing, reliability and performance are the best outrunners available in the market.

Programmable ESC to favour your different flying experiences. Good functionalities and reliable. An ideal upgrade for your 300-400 class EP helicopters (SJM 325 / 400, ESKY Belt-CP, Honey Bee King 2).
1.1 Output : Continues 35 A, Burst 40 A up to 10 Secs.
1.2 Input Voltage : 5.6V --- 16.8V ( L ithium : 2 – 4s or NiMH/NiCd 5 -12 Cells)
1.3 BEC (Battery Elimination Circuit) Output : linear mode BEC 2 A
1.4 Max Speed: 210,000rpm for 2 Poles BLM, 70,000rpm for 6 poles BLM, 35,000rpm for 12 poles BLM. (BLM: BrushLess Motor)
1.5 Size : 24mm*45mm*11mm (width*length*height)
1.6 Weight : 25 g
1.7 Packaging include:
3 sets of gold plated motor connectors and heat-shrink tubings (Remark: motor connectors and heat-shrink tubings need to be purchased additionally)
-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) : power 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: 2.6V/2.85V/3.1V. For example: 3 Cell Li-Poly, when medium cutoff voltage is set, the cutoff voltage is: 2.85*3=8.55V.
2) For Ni-xx battery, low / medium / high cutoff voltages are 0/45%/60% of the startup voltage. (0% means the low voltage cutoff function is disabled). For example: 10 cells NiMH battery, fully charged voltage is 1.44*10=14.4V, when medium cutoff voltage is set, the cutoff voltage is : 14.4*45%=6.5V
● Startup mode: normal / soft / super-soft, default is normal startup.
● Timing: low / medium / high, default is medium timing. In normal cases, low timing can be used for most motors. But for high efficiency, we recommend the Low timing for 2 poles motor and Medium timing for 6 poles and above. For higher speed, High timing could be used.
-Full Protection F eatures: Low-voltage cutoff protection / over-heat protection / throttle signal lost protection .
-Capacitor with extremely low resistance used on voltage input section, this will increase the ability of prevention of unwanted RF Noise/ Interference during flying.
-Extreme low resistance, super current endurance.
-Microprocessor and BEC use separate voltage regulator IC, with good anti-jamming capability.
