JR Vibe 90 SG

Get To Know "JR Vibe 90 SG"

VIBE 90SG is designed to be the most advanced 3D helicopter ever. Designed by Scott Gray and developed by JR Heli Division, the mechanics have been optimized for maximum strength, rigidity, and power transfer. Vibe 90™SG combines the ultimate in design, function and precision with JR’s legendary quality. JR Vibe is known world wide as one of the finest quality, top performing r/c helicopters available.

The Vibe is now taken to the next level - V90SG that combines years of experience from Scott Gray and Team JR’s top pilots’ requirements into one all-new machine. Features that are important to the competitive pilot and to the weekend flyer alike are strong features in the SG. A closer look at the design, quality, and features of this machine make it clear why the Vibe 90™SG is exclusive in many ways:

Freestyle True to all JR machines, there is something different about how the helicopter responds to the very thought of the pilot. Vibe 90™SG outperforms others by offering flight characteristics that usually just don’t exist together. Extreme cyclic agility and collective power meet with precision feel, straight line high speed tracking and predictability.

Precision Vibe 90™SG

is equally capable of FAI- F3C precision flight. The chassis strength and rigidity keeps noise and vibration down during hover, while boosting power output for high speed aerobatics. The highly tunable rotor head can be set to the perfect mix ratios for world class competition flight. The included multi-stage dampening system can be tuned to match blade and paddle selection for best all-round setup.    The JR Super Gracy F3C fuselage and many other popular high-speed bodies will easily fit the narrow and compact frames of the SG.
