Oversky 7A PnP Brushless ESC for Genius CP/Mini CP Helicopter Review

 

Oversky 7A PnP Brushless ESC

 

RC Pro Review by: Tom Zadar

 

Rick at ClubHeli sent me the Oversky 7A PnP Brushless Genius CP/Mini CP ESC to test out.

 

The Oversky 7A PnP Brushless Genius CP/Mini CP ESC has now been replaced with
the Oversky 10A PnP Brushless Genius CP/Mini CP ESC .

The Brushless Converter/ESC starts the motor very well.
It started the motor at the second line on the throttle stick every time even at 3.7V.
The WK-WST-10A-LT needs about half throttle to start the motor.

The Brushless Converter/ESC is easy to install as it is plug n play.
The pin holes for the motor plug are smaller than the standard size motor plugs.
For now I made an adapter so I could test the combo out, see pictures below.

 

Head Speed: – C05 motor w/9T pinion and the Genius CP main gear.

Oversky 7A PnP Brushless ESC.

  • 5,700 RPM at mid stick 100% throttle with the Hyperion 240 mah 25C battery.

Head Speed: – C05 motor w/9T pinion and the Genius CP main gear.

WK-WST-10A-LT (ESC/Converter).

  • 5,610 RPM at mid stick 100% throttle with the Hyperion 240 mah 25C battery

 

Flight Time: – C05 motor w/9T pinion and the Genius CP main gear. Hyperion 240 mah 25C battery.

Oversky 7A PnP Brushless ESC.

  • 1 Minute: 3.95V
  • 2 Minutes: 3.85V
  • 3 Minutes: 3.76V
  • 3:30 Minutes: 3.74V – Power getting low.
  • 4 Minutes: 3.70V – Power very low, had to land.

Flight Time: – C05 motor w/9T pinion and the Genius CP main gear. Hyperion 240 mah 25C battery.

WK-WST-10A-LT (ESC/Converter).

  • 1 Minute: 3.98V
  • 2 Minutes: 3.84V
  • 3 Minutes: 3.76V
  • 3:30 Minutes: 3.72V – Power got very low and I had to land.

 

Weight:

  • Oversky 7A PnP Brushless ESC: 2.5 grams with wires
  • Oversky 7A PnP Brushless ESC: Bare board weight – 1 Gram
  • WK-WST-10A-LT (ESC/Converter): 3.3 Grams

 

The last two pictures are the Oversky 10A PnP Brushless MCPx ESC which is the same as
the Oversky 10A PnP Brushless Genius CP/Mini CP ESC except for the RX signal wire. 1 is + PWM and the other is – PWM.

 

Programming function:

It can be programmed in 8 ways:

1) BRAKE: shut off/soft brake/hard brake, default is shut off.

Shut off———–When throttle is at the lowest position, the motor will stop running slowly.

Soft brake—– When throttle is at the lowest position, the motor will stop with less force and brake time can be longer.

Hard brake—– When throttle is at the lowest position, the motor will stop instantly with more force. ?

2) Timing: low/middle/high, the default is middle.

Low——is recommended for high inductance or low KV motors

Middle——is compatible method for both high timing and low timing mode

High—— is recommended for low inductance or high KV motor

3) Start Mode: Fast/Soft/Very Soft, the default is Fast

Fast———No delay response from start to highest throttle, it is for direct drive fixed-wing airplanes

Soft Start———2 seconds response delay from start to highest throttle, it is for gearbox fixed-wing airplanes or helicopter

Very Soft——4 seconds response delay from start to highest throttle, it is for fixed-wing airplanes with gearbox or helicopters

4) Cut off type (low voltage protection mode): Reduce power and Cut off output power for selection, default is Reduce power

Reduce power——when the voltage is less than the setting voltage, ESC will reduce output power from the motor

Cut off power—— when the voltage is below the setting voltage, ESC will cut off power instantly

5) Throttle curve: Curve1/Curve2/Curve3, the default is Curve 1

6) Lipo battery numbers:automatically check/2 cells/3 cells/N cells,the default is automatic checking( no this choice for ESC only working with 1S pack)

7) Low Voltage protection: low(2.8V)/Middle(3.0V)/High(3.2V), the default is middle(3.0V)

8) Motor Rotation: Forward /Reverse

Normally, Forward and reverse rotation can be realized by exchange two wires on the motor. If the motor and ESC has been soldered and not convenient for exchanging the wires on the motor, Forward and Reverse rotation can also be realized by setting the ESC.
