This is the Skookum SK 540 3-Axis Flybarless System. The SK 540 is a next-generation flybarless system and is ideal for any pilot wanting a no-frills, rock solid flybarless control system. The SK 540 features 3D Masters-proven flight control, dual 3-axis MEMS gyros, and an integrated governor. Whether youíre new to helis or youíre already flying smack 3D, the SK 540 is ready for you!

The SK 540 was developed in response to SK 720 pilots who loved the unitís flybarless control, but didnít feel the need for the self leveling function or GPS capability. As a result, Skookum took the accelerometers out of the SK 720, included two redesigned 3-axis MEMS gyros and an updated 32-bit processor, then packaged it in an updated anodized and laser etched aluminum case. The SK 540 also loses the need for the SK-SB1 SBus adapter Ė SBus receivers can be directly connected to a port on the SK 540′s servo bus.


  • Dual 3-axis MEMs gyros, giving stability and redundancy
  • 32-bit processor
  • Anodized and laser etched aluminum case
  • Compatible with DSMX, DSM2, DMSS,  Futaba SBus (without SBus adapter!), PPM and Traditional receivers
  • Easy to use Setup Wizards and compatibility with SK 720 setup files
  • Supports use as a 8-channel receiver core when used with Spektrum Satellites, Futaba SBus, or PPM receivers
  • Works with Digital or Analog swash servos, as well as high voltage servos
  • Suitable for 120, 135/140, and 90 degree eCCPM, as well as mCCPM swashplates
  • Works with 2,3,4, or 5 blades, with phase trim adjustable to Ī90į
  • Swash Ring anti-binding algorithm
  • Internal swash mixing, for accurate control
  • Supports Spektrum radios with either 1024 or 2048 servo steps, and 22ms or 11ms frame rates
  • Quadcopter flight control (beta)

In Depth Features:

  • Fast Performance: The SK 540 inherits the high performance flight control from its big brother, the SK 720. Like the 720, the SK 540 integrates the yaw and cyclic gyros, giving rock-solid piro maneuvers and tail control that benefits from knowing what the collective stick is doing. For pilots looking for lightning fast piros, the SK540 is capable of 3 full rotations in one second!
  • Easy Setup: The Setup Wizards from the SK 720 have carried over to the SK 540 as well. These wizards will guide you through simple steps, having your heli ready to fly in no time.  Have a favorite SK 720 setup? The SK 540 can load it directly onto the unit! Video walkthroughs of Setup Wizards are also available on the Skookum YouTube channel, making setup even easier.
  • Big Features without a big Price: Along with the flybarless control from the SK 720, the 540 keeps a number of functions that made the SK 720 a market leader for features in a single unit.
  • Integrated Governor: Your heliís setup is simplified with the SK 540′s integrated governor. Simply plug your RPM sensor into the IO-C port, enter your gear ratio into the SK 540 software, and set your RPM values.
  • Quadcopter Compatibility: Quadcopter pilots get a compact and easy to use flight control solution with the SK 540 Ė no soldering, no open circuit boards. Just connect the ESCs, tell the SK 540 which way itís pointed and fly!

Weight: 18g (0.63 ounces)
Dimensions: 29x38x13mm (1.125x1.5x0.5in.)
