Vibe service bulletin

Through reports from some of our Team JR members in the field it has come to or attention that there have been a small percentage of Vibe helicopters that have experienced severe tail vibration and in a couple instances lost tail rotor blades. This is obviously a very serious condition that can result in a catastrophic crash.

Through extensive research we have traced the cause to an improperly secured bolt on the tail clamp (#JRP960133) thus allowing the tail rotor gear box to rotate on the tail boom in flight. In some cases the tail rotor blades strike the vertical fin resulting in the grips and or rotor hub being destroyed. In less severe instances a resonance (vibration) occurs in the tail rotor system/gearbox. This resonance is primarily occurring when the tail clamp (#JRP960133) is insufficiently tightened allowing the tail rotor gearbox to resonate in the tail boom resulting in extreme stresses being placed on the tail hub, blade grips and tail blades which in time will fail.

Important: The tail clamp (part #JRP960133) fastens the tail rotor gearbox to the tail boom and must be securely clamped in place to prevent gear box rotation and or tail resonance/ vibration. This requires that the 3mm x15mm socket head bolt (JRP980015) be securely tightened such that the clamp compresses the tail boom fixing the tail rotor gearbox in place. It’s necessary to use adequate force when tightening this 3x15mm screw so that the clamp compresses the tail boom firmly securing the tail rotor gearbox in place. Note that the tail clamp is also used to attach the rear portion of the vertical fin in place. It’s very important to fully tighten the 3x15mm socket head bolt that tightens the clamp and secures the tail rotor gearbox in place BEFORE the vertical fin is attached. If the vertical fin is installed first it’s possible that the screw attaching the fin to the clamp will prevent the 3x15mm clamp bolt from fully seating preventing the clamp from securely fastening the tail rotor gearbox in place.

in pratica prima di stringere le viti della pinna ,prima devi stringere la vite opposta del mozzo coda.
ciao

[Dredd]

altrimenti ti accorgi della ciofeca di modello che hai comprato eheh

[massi69]

infatti mi sa che e' l unico marchio che sui ely(forse?) ti danno 2 anni di garanzia , poi se monti male cavoli tuoi.
ciao

Urca se sono prolissi alla JR. Tutto quel papiro per dire di stringere due viti? Comunque gira e rigira viene fuori che anche il Vibe hai suoi problemini come tutti gli altri 90 in circolazione. Eccetto forse lo Style.
