How to kill an expensive servo !



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 !
