The SK-720 replaces the tail gyro, mechanical flybar, and receiver on your R/C Helicopter. Other features include flight logging with playback, optional-self leveling, and more to come! This unit is ideal for pilots from beginner to 3D expert. Go flybarless!
- * Easy set up for first-time users
- * Flybarless stabilization with piro-compensation
- * Built-in tail gyro, supporting most all tail servos by name in the setup software
- * Supports use as a 9-channel receiver core when used with 2.4 GHz
- satellite receivers (two dedicated Sat-RX ports)
- * Works with Digital or Analog swash 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 +-90°
- * Swash Ring anti-binding algorithm
- * Internal swash mixing, for accurate control
- * Supports radios with either 1024 or 2048 servo steps, and 22ms or 11ms frame rates
- * Can also be used with traditional R/C receivers
- * Expansion port for future accessories such as GPS
- * 38 x 30 x 14 mm, 17 grams
- * 8.5 volt capable
- * Optional 20 amp external power bus (included) for larger than 50-size and nitro helis (15 grams). Make brownouts a thing of the past!
- * 3-axis accelerometer + 3 gyros, allowing self-leveling
- * High-power 32 bit processor (for future upgradeability)
- * Expansion port for GPS or a third sat-receiver

Features
- Overview
- The SK-720 can greatly simplify your heli’s setup, by eliminating the flybar mechanics, tail gyro, and with the use of satellite receivers (not included), the receiver core and associated wiring as well.
- But more than just a flybarless system, the SK-720 is a complete 6-degree of freedom inertial flight control system. So what does that mean for you?
- Fast Performance
- For 3D pilots, the SK-720 integrates the yaw and cyclic gyros, giving rock-solid piro maneuvers and tail control that benefit from knowing what the collective stick is Power Busdoing. Flybarless flight gives you more power with less bogging, and a locked-in control feel that is far superior to traditional flybar flight.
- Improved Stability
- For beginners or those learning 3D, the SK-720’s built-in 3-axis accelerometer means you can set it to self-level, like a coaxial heli. This feature can be turned on full time, dialed down as your skills improve, or set to bail you out at the flick of a switch. Plus, a flybarless heli has greater stability than a heli with a flybar, and with fewer parts, is easier to repair. Small 450 size helis become as stable as 90-size helis. The SK-720 will allow every new pilot's first R/C helicopter to be flybarless.
- Flight Logging
- For all pilots, the SK720’s built-in flight logging lets you record and play back your flights in a simulator-like display on your PC (like a black-box recorder). Both the heli’s motion and the stick positions are displayed, letting you learn exactly where you can improve your skills – or why you crashed. The playback software can also be used as a diagnostic tool, warning you of voltage dropouts and high vibration, while marking where in the flight they occurred.
- Helis Big & Small
- For pilots flying micro-helis, the SK-720 will greatly simplify and lighten your machine. It also has a special small-heli tail gyro mode to give good holding power even on 250-size helis.
- SK-720 Digital FlybarIf you fly larger helis, the SK-720 includes a heavy-duty external power bus that’s good for 25 continuous amps, and helps to isolate vibration from the gyro itself. The bus allows for high voltage servos, low voltage servos, or a combination of both, and includes 16 gauge cabling to connect directly to a 2-cell lipo battery.
- Easy Setup
- The PC setup software has wizards to guide you through setting up your first flybarless heli in just minutes – making it easier to set up an SK-720 machine than a heli with a traditional flybar!
- The setup software or optional SK-LCD terminal lets more advanced users fully tune their heli for max performance. And it's easy to upgrade the firmware at home so you'll benefit from any future product improvements with just a click of your mouse.
- Future upgrades will include a GPS accessory for more precise xyz positions in the flight logs, as well as abilities entirely new to the hobby.
