Random shaking

aleung · 03-08-2012, 05:25 AM

My Rave 450 flies ok but randomly shakes, any idea how I can get it fixed? Is it the gyro tape, I am strapping the Total G down with Velco at the moment, may remove the Velco tomorrow and try.

What type of shake ? Aileron or elevator?

Aileron, side to side I think a bit front and back

Sometime a wobble or shake can be caused by too low a head speed with the head damping being too tight.

What is your headspeed?
Have you recently changed out your head dampers?
Which head dampers are your using?
Are they glued in?

What kind of gyro tape are you using? How many layers?

Did you change anything?
Was this after a crash?
I would try lowering the tail gain first. If that does not help then start going over the tail assembly. Pop the link off the rudder servo and check for binding - try moving the control rod back and forth. Check for slop at the tail rotor grips.
Let us know

Check if your TT is split.

Easy way to tell is hold the head and try to turn the tail. If there is any spring feel too the tail, your TT is broken/partially split.
