HOBBYWING REG. ROTATION OF THE SKYWALKER 20A

Programmable microprocessor speed controller for AC motors without sensors ("brushless, sensorless") designed based on the capabilities of the latest semiconductor technology with excellent performance properties while maintaining a very simple and user-friendly operation. It is used to control the speed of AC motors in recreational aircraft models powered by NiCd / NiMH and Li-Poli / Li-ion batteries. It is equipped with a BEC linear power stabilizer that supplies power to the receiver and servos from the drive battery. A special Hobbywing LED programming card, which is supplied separately, is used to easily adjust the controller.

DESCRIPTION AND FUNCTIONS OF THE CONTROLLER:

• Extremely low internal resistance thanks to the new generation of power MOSFET transistors.
  
• Suitable for most airplanes with AC motors powered by 2-3S LiPo / Li-ion batteries or 5-9 NiCd / NiMH cells.
  
• For operation with NiCd, NiMH, Li-poly, Li-ion batteries
  
• Linear power stabilizer BEC 5.0 V - load up to 2 A.
  
• Adjustable time for optimal adaptation to the respective engine.
  
• Regulated PCO circuit - disconnection of the motor when the supply voltage drops.
  
• Safe starting (prevents the engine from starting when turned on).
  
• Overload protection (when the temperature reaches 110 ° C, the controller limits the power).
  
• Automatic gas intake in case of loss of the control signal.
  
• Continuous linear gas regulation.
  
• Easy to program and set using the transmitter or the Hobbywing LED programming card.
  
• Gas span calibration for a perfect match to the control signal from the RC kit.
  

PROGRAMMABLE FUNCTIONS:

• Programmable brake (off - on).
  
• Optional battery type (Li-poly or NiCd / NiMH).
  
• Adjustable method of disconnecting the motor in the event of a voltage drop (power reduction or immediate disconnection).
  
• Adjustable limit voltage for engine disconnection, PCO - protection against excessive battery discharge. (Lithium battery: 2.85V / cell, 3.15V / cell, 3.3V NiXX battery / cell: 0% / 50% / 65% of the initial voltage value.)
  
• Resetting the controller settings to factory default settings.
  
• Adjustable timing (advance) - for increased performance and optimal engine alignment - Low (3.75 °), Medium (15 °), High (26.25 °)
  
• Adjustable soft start of gear motors and helicopters in three stages: normal (300 ms) / gentle (1.5 s) / super soft (3 s).
  

PROTECTIVE FUNCTIONS OF THE REGULATOR:

• Anti-start protection: If the engine does not start within 2 seconds after adding the accelerator, the controller shuts down the engine.
  
• Thermal protection: If the controller temperature exceeds 110 ° C, the controller will limit the output power.
  
• Loss of gas signal: Regulator limits power if no signal for 1 s; no signal after more than 2 seconds will cause complete engine shutdown.
  

Tip: When turning on the regulator for the first time, first calibrate the gas range according to the instructions. Only then can the driver be used and other parameters can be set using the transmitter or LED programming card.
