Is it as necessary to use the rubber isolation pads in mounting wing aileron servos. My ESMdirections show mounting the servo directly onto the wing plate and sandwitched between two blocks of wood, into which the screws are set. This direct contact would seem to defeat the use of the rubber mounts. The installation onto the tray within the fuse seemsto be another matter, where the servo is set into a cut out and not in direct contact with the mount board, short of the rubber isolated screws. Am I seeing this right, or should the wing servos (ailerons and flaps) be totally isolated?
