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.

The shipping package contains:

 Features:
◆ 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.

Why upgrade from oil sealed to water/ceramic sealed)?

Add a ceramic ring in the middle, reduce the direct contact between the sealing ring and the bearing, extend the life of the bearing; improve the waterproof performance

Update Detail:

Water-seal has 2 parts as the following pictures
2 strong hardness ceramic run with each other and metal ring part spins together with shaft&ball bearing,
which can prevent the abration between shaft and water-seal, extend the motor lifespan with better IP rate.

Kindly Reminder !

1.Please carefully check following receiver connection diagram corresponding with different FSESC, wrong cable collection in reciver side will cause the receiver burned. 

2. The variants (for VESC4/ for VESC6 / For Non VESC) only differenciate on reciver cables , the remote is the same one. 

3. When you choose UART mode connection for VX1 remote receiver, pls do connection after your programming in VESC tool. Or else , it will influence programming. And In UART mode, there is no need to do adjust for remote.

The advantage of the Seal 300A 60V ESC

1. Light-weight, compact, small size perfect ESC for racing in mono.
2. Over-heat protection, low-voltage protection and lost-signal protection.
3. Programmable via PC interface, LCD programmer and PC interface and LCD progam card.
4. Smaller MOSFET to minimize weight.
5. Extremely lower internal resistance.
6. Super smooth throttle linearity.

Throttle Calibration:

If the Marine ESC is used for the first time or the transmitter is changed, You have to
make the throttle calibration to attain the smoothest throttle response and resolution
throughout the entire throttle range of the transmitter, This step is done once to allow the
ESC to “learn and memorize" your Transmitter's throttle output signals.
Please note, Marine ESC has two different modes“One Way”and "Two Way". You can
get into these two different modes by different throttle calibration way.
ONE way mode:
1. Switch your Transmitter ON and set the throttle stick to its maximum position.
2. Connect the battery pack to the ESC, Wait for about 2 seconds, the motor will beep for
twice, then put the throttle to the minimum position, the motor will also beep which
indicates that your ESC has got the signal range of the throttle from your transmitter.
TWO way mode:
1. Switch your Transmitter ON and set the throttle stick to its maximum position.
2. Connect the battery pack to ESC, Wait for about 2 seconds, the motor will beep for twice.
then put the throttle to the neutral position, the motor will also beep which indicates that
your ESC has got the signal range of the throttle from the transmitter.

Wire Connection:

The speed controller can be connected to the motor by soldering directly or with high
quality connectors. Always use new connectors, which should be soldered carefully to
the cables and insulated with heat shrink tube. The maximum length of the battery pack
wires shall be within 6 inches.
For normal ESC with BEC output please see as follows:
