When mounting the rudder servo at the tail rotor end of the tail boom, many
users (Raptor users especially !) mount the servo with the mounting plate above
the mounting lugs. As most JR servos have a flange to support the mounting lugs
at the top, this flange is compressed against the servo plate and feeds all
vibration direct to the servo in spite of the mounting rubbers. The solution is
to file slots in the servo mounting plate to clear the flanges so that the
mounting rubbers can do their job. Some heli frames already have the
notches in place.
Please click here to see a servo that has been compressed against the mounting plate which does not have the notches in place.
It doesn't look much but the fact that there are indentations show that the
rubber anti-vibration dampeners were bypassed. There should be NO marks
whatsoever on the servo case top.
A few minutes care and attention will prevent an unnecessary failure of a
valuable servo and save your expensive Heli from disaster!
