Designed by world-class heli pilot Scott Gray, the latest addition to the Vibe family of helicopters oers the ultimate
in aggressive ight performance and is designed to withstand the stresses of the most extreme aerobatic and 3D
maneuvers, even those that have yet to be imagined. Features like the oversized tail and main shafts, the oversized
Sprag autorotation clutch and 10mm spindle shaft that can handle the most aggressive maneuvers, a robust split
gear constant-driven tail rotor and a lightweight, rigid structural design make the Vibe 90™ SG an unbeatable
choice for heli pilots who want to push 3D performance beyond the edge. If you’ve been waiting for a helicopter
design that has unlimited ight performance with the reliability and the durability to handle the most demanding
aerobatics…your wait is over. Once you take the controls of the Vibe 90 SG, you’ll know your wait was worth it.

When rst opening your helicopter, you will notice that all of the parts are packaged and numbered to coordinate
withtheassemblystepnumbersofthisinstructionmanual.Allsmallhardware(nuts,bolts,washers,etc.)foreach
step is separated and packaged separately within the main parts bags. When beginning a section, you will need to
open only the bag with the corresponding number to the section you are going to start. It is suggested that you
place all of the hardware in an open container (e.g., coee can) during assembly so as not to lose any of the small
parts. It may also be helpful to familiarize yourself with the various sizes of screws, bolts, nuts, etc., as illustrated
intheappropriateassemblysectionbeforeyoubeginassembly.Attheendofeachassembly,inmostcases,there
should be no parts remaining.
NOTE: Your kit also includes JR® red and green threadlock. Unlike conventional U.S.-made threadlock,
JR red is the U.S. equivalent of blue. JR green is the equivalent of U.S. red.
