  • Agile 5.5 Helicopter Kit

    Agile Kit 5.5 (size 550) with main and tail  blades

    Review of the model by Ben Varley (UK)
    The Agile has been designed to offer something different, not just an improvement, but a step ahead of what is commonly done. The Agile was created to adapt to every type of flight: low to high speed, gentle maneuvers, Hard to 3D unimaginable level!
    Intelligent solutions have been used to provide high-end performance with very sensitive controls, giving a feeling of incredible strength while maintaining softness in movement.
    To ensure that nothing is left to chance and bring you the best overall design, hundreds of test flights were carried out by experienced drivers.
    Agile is agility AND quality, you can’t go wrong!

    PROPELLER specs.

    •   APC Electric propellers have been designed specifically for electric powered model airplanes.
    •   APC Computer optimized design gives these propellers a thinner profile and more "bite" with less weight compare to standard glow propellers.
    •   Lightweight molded nylon construction reduces rotating mass for less drag and more efficiency.

  • BavarianDEMON Helicommand RIGID V.2 Stabilization Assistant for Helicopters

    3-axis stabilization system for RC helicopters
    Demonically safe: With "Autopilot" function
    Ideal for beginner


    • Stabilizes all horizontal control movements plus tail
    • RIGID mode for stabilization of flybarless rotor heads
    • Fail-safe function
    • For all types of helicopters
    • Auto-trim function
    • Integrated swashplate mixer
    • PILOT (stabilization) + AUX (tail gyro) channels
    • Linearisation of servo movements
    • Virtual swashplate rotation


    The bavarianDEMON 3X is especially aimed at extreme 3D pilots, but also works X-tremely well for all other flybarless helis. Latest software algorithms, intelligent sensor technology combined with an unprecedented power, all this fitting the entire range of flybarless helicopters, electric, nitro, gaser and turbine powered. Because they are lighter, helicopter models without flybar are much more agile and maneuverable, and are approx. 15% more powerful. In combination with the bavarianDEMON 3X , huge performance is delivered, without the need to adjust the fragile flybar mechanism.
