HOBBYWING REG. OBROTÓW FLYFUN 20A - V5 (HW30202308)

Hobbywing speed governor for model aircraft.
New generation of programmable microprocessor controllers for AC motors without sensors ("brushless, sensorless") for large models of recreational and sports aircraft powered by Li-poly / Li-ion / Li-Fe batteries. Compared to the previous generations of FLYFUN regulators, the programming options have been extended with a number of functions that have proven themselves in the top Platinum series regulators. The design of the controller takes into account the high load and durability required in large models. The regulator is equipped with a powerful BEC pulse power stabilizer with an optional output voltage that provides power to the receiver and servos (normal and HV) from the supply battery. A special Hobbywing LED programming card, which is available in our store ( HOBBYWING GENERAL LED PROGRAM CARD - HW30501003 ), is used for easy and quick programming of the controller.

DESCRIPTION AND FUNCTIONS OF THE CONTROLLER

• The controller is equipped with a high-performance 32-bit ARM M4 microprocessor with a clock frequency of up to 72 MHz; it is compatible with most AC motors.
• Suitable for most airplanes with AC motors powered by 2-4S LiPo / Li-ion / LiFe batteries.
  
• A special power stabilizer for the microprocessor provides high noise immunity and reduces the risk of loss of control.
  
• The DEO (Driving Efficiency Optimization) technology significantly improves the gas response and the efficiency of the power stage control, lowers the temperature of the regulator.
  
• Normal / Soft / Very Soft take-off modes are suitable for regular propeller planes as well as models with blowers.
  
• Easy to program and set using the Hobbywing LED transmitter or programming card.
  
• A special programming cable for connecting the regulator to the LED programming card enables the user to program the regulator at any time and place (details in the Hobbywing LED programming card manual).
  
• Normal / Proportional / Reverse brake modes (especially Reverse mode) can effectively shorten the range after landing.
  
• A number of protection functions: starting protection, controller thermal protection, capacitor thermal protection, overload protection, overcurrent protection, protection against incorrect supply voltage and protection against loss of the control signal effectively extends the life of the controller.
  
• Gas span calibration for a perfect match to the control signal from the RC kit.
  

PROGRAMMABLE FUNCTIONS

• Brake type: disengaged brake, normal brake (with 7-stage brake intensity adjustment), proportional brake (throttle-controlled: 0-20% accelerator deflection corresponds to 100-0% braking, 20-100% rudder deflection corresponds to 0-100% throttle) ), reverse (allows you to turn on the reverse of the engine operation with another channel with a switch).
  
• Braking force: The braking intensity can be adjusted from level 1 to level 7 in "normal braking" mode.
  
• Motor shutdown method: Soft shutdown: The controller gradually reduces the power to 50% of full power within 3 seconds of activation of the voltage protection. Hard shutdown: the engine shuts down immediately.
  
• LiPo cell count: We recommend manual setting of 100% reliable voltage protection function. The controller automatically calculates the number of cells of the connected battery according to the principle of "3.7 V per cell" if automatic detection is selected.
  
• Voltage protection: The threshold voltage protection level is adjustable from 2.8-3.8V / cell; the protection can also be completely disabled.
  
• BEC voltage: The BEC voltage of the power stabilizer can be adjusted to 5.2V, 6.0V or 7.4V.
  
• Starting: Normal start (immediate start), Soft start (slow start for engines with large propellers, gearbox or smaller blowers), Very soft start (very slow start for engines with large propellers, gearbox or blowers from 90 mm).
  
• Time: adjustable from 0-30 °.
  
• Direction of rotation: clockwise / counterclockwise.
  
• DEO freewheel: This function can be turned on or off; may result in better linearity or a smoother gas response.
  

PROTECTIVE FUNCTIONS OF THE REGULATOR

• Start-up protection: The governor measures the engine speed during start-up. If the speed stops increasing or the speed increase becomes unstable, the controller evaluates this as an abnormal start. If the throttle is less than 15% at this point, the controller will automatically try to restart the engine; if the throttle is greater than 15%, pull it all the way to restart the engine.
• Controller thermal protection: The motor "stall" if the controller temperature exceeds 110 ° C, which means that the thermal protection has tripped. If at this point you pull the throttle below 60%, the stall will disappear and the regulator will deliver the power corresponding to the throttle position. If you move the throttle above 60%, the "stall" reappears. The temperature of the controller during start-up must not exceed 70 ° C, otherwise the engine cannot be started.
  
• Gas signal loss protection: The controller shuts down the engine immediately if the signal is missing for 0.25 seconds to prevent even more damage and hazards from a fast rotating rotor or propeller. After receiving a normal signal, the controller returns to normal operation.
  
• Overload protection: The controller shuts down the motor or restarts automatically when its load suddenly becomes very high.
  
• Overcurrent protection: the controller immediately shuts down the motor if the peak current draw exceeds the maximum allowable value; then resumes normal operation. If the current consumption still exceeds the maximum permitted value, the motor is completely shut down.
  

Note: When switching 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.
