Users must have a certain concept of security to operate the R/C helicopters.
Be sure to read and comply with related safety notes of instruction manual before flying.

Instruction (3G Programmable Flybarless System):                  Instructions
- 3-axis gyroscopic flybarless system to simulate the stability of mechanical flybar system, yet at the same time achieving agile 3D performance
- Utilizes Silicon Micro Machine (SMM) sensors for excellent stability
- 12 bit processors providing ultra high resolution, resulting in highly precise controls
- Software upgradable through PC interface adapter (sold eparately)
- Simplistic setup process without the need of external devices. Setup is done through 5 steps and 2 sensitivity adjustments. Rudder setup is identical to GP780 gyro, minimizing learning curve
- Flybarless system dramatically improves 3D power output and efficiency, resulting in reduced fuel or electricity consumption
- Highly sensitive gyroscopic sensors combined with advanced control detection routine providing higher hovering and aerobatic stability than other flybarless system
- Suitable for all CCPM and mechanical mixing system
- Comaptible with helicopter of all sizes from T-Rex 250 to T-Rex 700
- Innovative Pitch Gau as an aid to facilitate pitch adjustments
- High frame rate signal output for faster and higher precision servo response
- Capable to operate between 3V to 8.4V, compatible with high voltage servos
- Small footprint, light weight, minimalists and reliable design
