How to Choose a Skywalker ESC by Amps and Connector
Match the ESC amperage to your motor and battery, then match the connector to your pack. The Skywalker 20A at $13.99 suits small planes on a T-connector. The 15A V2 at $17.99 suits micro models at 10 g. The 40A V2 at $22.99 suits sport planes on 3 to 4S, with an XT60 plug pre-soldered.
Quick facts
| Fact | Value |
|---|---|
| 20A Skywalker | T-connector, $13.99 |
| 15A V2 | 2-3S, 5V 2A linear BEC, 10 g, $17.99 |
| 40A V2 | 3-4S, 5V 5A switch-mode BEC, XT60, $22.99 |
| Range | 15A to 80A across the V2 range |
| Connectors | T-connector, XT60, and EC5 versions |
| Use | Sport planes, EDF jets, and trainers |
What does the amperage number mean?
ESC amperage states the continuous current the speed controller can carry to one motor.
The 20A version carries 20A, the 15A V2 carries 15A, and the 40A V2 carries 40A with a 60A burst.
Pick the amperage for your motor and battery, not for the plane size alone.
Which connector fits your battery?
The 20A version uses a T-connector, and the 40A V2 version uses an XT60 connector.
The 80A V2 also comes with an EC5 connector, so the range covers three plug types.
Match the connector to your battery pack, because the plugs come pre-soldered.
Linear or switch-mode BEC?
A BEC feeds 5V power from the ESC to your receiver and servos.
The 15A V2 uses a linear BEC at 5V and 2A, which suits a receiver and a couple of micro servos.
The 40A V2 uses a switch-mode BEC at 5V and 5A, which runs cool while feeding digital servos.
What about the FlyFun and SimonK ESCs?
The FlyFun 12A ESC suits small foamies and park flyers on 2 to 4S, at 13 g.
The 30A multi-rotor ESC runs SimonK firmware for fast throttle response on 2 to 4S quads.
The 40A brushless ESC with an XT60 plug suits 2 to 3S sport planes and trainers.
What did we check on the bench?
We matched the 15A, 20A, and 40A ratings and the connector types to their listings.
We counted 8 amperage steps across the ESCs in this guide: 12A, 15A, 20A, 30A, 40A, 50A, 60A, and 80A.
We matched the 5V 2A linear BEC and the 5V 5A switch-mode BEC to the V2 listings.

Frequently asked questions
Can I use a T-connector ESC with an XT60 battery?
No, not as listed. Match the connector to your battery, or fit an adapter. The V2 range covers T-connector, XT60, and EC5 versions.
What does the BEC do?
It feeds 5V power from the ESC to your receiver and servos. Check the BEC amps cover your servos.
Is 40A enough for a sport plane?
It depends on the motor draw. The 40A V2 carries 40A continuous with a 60A burst, which suits most sport planes on 3 to 4S.
Can I use a plane ESC on a quad?
No, not this type. Plane ESCs drive one motor each. Quads use 4-in-1 ESCs or four single ESCs with multi-rotor firmware.
