The Flipsky ESC is based upon the VESC Open Source Project, and compatible with VESC Software.

The Flipsky ESC is a highly modifiable electronic speed controller designed for DIY Electric Skateboards conversions in mind.

The Flipsky ESC allows you to use sensorless motors to achieve smooth start-up from a stop,while traditional RC ESC's may have trouble starting. It also provides strong reliable and progressive electric braking.

Why FSESC are better than other ESCs?

Flipsky ESC Advantages:

  1. Flipsky ESC has the ability to do many things a normal RC ECS can not.
    A.To limiting the amount of amps that come from your battery to your motor. An easy way to burn up a motor is by sending it more amps than it can handle for too long (often while riding up a hill). This means you should never burn up a motor with a FSESC (unless you set this limit too high).
    B.There’s also many other protections that can be set through limits, such as the max temperature you want the FSESC to get to (so you can’t burn up the speed controller), min and max input voltage (so you can’t pull the voltage of your battery under a safe limit, which would brick your battery), and max regenerative break amps (protects battery from having too many amps sent back in to it).
  1. FOC(Field Oriented Control) makes the motor more smooth and less noise and even saving  much power.
  1. Flipsky ESCs come with 3pcs pf 680uf 63V capacitors which are soldered on the capacitor PCB. The capacitor are very important for every ESC. They can make the ESCs’ stability when the ESCs speed up or slow down.

Why do we solder the capacitors on the capacitor PCB?
A.The capacitor PCB can stabilize the 3pcs 680uf 63V capacitors better than those are attached on the cables.
B.The capacitor PCB make the FSESC look good and clean.


◆ STM32F4  32Bit ARM micro-controller.
◆  DRV8302 MOSFET driver / buck converter / current shunt amplifier.
◆  6pcs IRFS7530 MOSFETs.
◆  Regenerative braking.
◆  DC motors are also supported.
◆  Sensored or sensorless operation.
◆  Adaptive PWM frequency to get as good ADC measurements as possible.
◆  Good startup torque in both sensored and sensorless mode.
◆  Duty‐cycle control, speed control or current control.
◆  Wireless WII nunchuk (Nyko Kama) control through the I2C port. This is  convenient for electric skateboards.
◆  Optional PPM signal output. e.g.  when controlling an RC car from a  Rasp Berry Pi or an android device.
◆  The USB port uses the modem profile, so an Android device can be   connected to the ESC without rooting. Because of the servo output, the odometry and the extra ADC inputs(that can be used for sensors),  this is perfect for modifying an RC car to be controlled from Android  (or Raspberry Pi).
◆  Sensored and sensorless (FOC) Field Oriented Control allows your electric skateboard to run with barely any motor noise, it auto-detects motor parameter since FW3.34.
◆  Many safety features such as current control and temperature control features.
◆  The motor is used as a tachometer, which is good for odometry on modified RC cars.
◆ Adjustable protection against:
Low input voltage
High input voltage
High motor current
High input current
High regenerative braking current (separate limits for the motor
and the input)
Rapid duty cycle changes (ramping)
High RPM (separate limits for each direction).
◆ When the current limits are triggered, a soft back-off strategy is used while the
motor keeps running. If the current becomes too high, the motor is switched off completely.
◆ The RPM limit also has a soft back-off strategy.
◆ Commutation works perfectly even when the speed of the motor changes. This is due to the fact that the magnetic flux is integrated after the zero crossing instead of adding a delay based on the previous speed.
◆ When the motor is rotating while the controller is off, the commutations and the direction are tracked. The duty-cycle to get the same speed is also calculated. This is to get a smooth start when the motor is already spinning.
