    The AvA 299 DROP is a helicopter designed to take crazy snowboarders to locations not accessible by normal lifts. The entire cabin can lower them just enough to leap out and carve their stake across a mountain. The coaxial rotor blades spin in opposite directions to provide more power and negates the need for a tail rotor for stabilization. The design also addresses a number of problems with single blade rotors. Hit the jump!

    • Settling with power – Reduced
    • Retreating blade stall – Reduced
    • Medium frequency vibrations – Reduced
    • High frequency vibrations – None
    • Anti-torque system failure in forward flight – Eliminated
    • Anti-torque system failure while hovering – Eliminated
