The most competitive .50 ever designed

Hirobo’s new SDX .50 features cutting-edge head design that borrows technology from the Turbulence .90, winner of the 2007 Masters and 2008 XFC Championships. More tunable and adjustable than any .50, the SDX can be adjusted to meet a wide range of performance levels… from beginners learning to hover to seasoned 3D or F3C pilots challenging the skies.

The new FZ-5 Rotor Head delivers the most precise control ever created for a .50 size ship.

• The rotor head furnishes outstanding control for any maneuver, while a precision machined, aluminum hub and spindle design easily cope with the most demanding 3D flying.
• An end to interaction… all three control bell cranks rotate on a single pivot as opposed to the conventional two or three. In addition, the new swash plate delivers almost 60% more precise movement than our older aileron and elevator throws… result: there’s no binding, and we’ve virtually eliminated control interaction
• Two mixing options… unlike ordinary.50s that deliver only 120º eCCPM mixing geometry, the SDX provides both 120º and 135º options for unprecedented precision and rock solid control
• A whopping 30º collective pitch range delivers the “POP” required for 3D. In addition, cyclic range approaches 9º of deflection for exceptionally quick pitch and roll rates
