OK I have another question. I am going to install a Futaba S3154 digital servo on the tail rotor. It has a slightly different case than the S3107's for which I used on the swash. The difference is the holes in which are drilled for mounting (one at each end) are small and are not open to allow the rubber grommets/brass eyelets to slide into (It doesn't come with them either) like the 3107's do. Not to mention the hole to hole center distance is slightly shorter. This leads up to my question. How are the 3107's being mounted onto the factory openings in the frame with respect to using the rubber grommets/brass eyelet bushings etc? I am sure I could get out the dremel and make the holes just like the 3107's and then they would accept the grommets/brass eyelet bushings if I have to. I suppose I could even allow the servo case to contact the frame directly, but I have always had some sort of a cushion between the servo case and the aircraft frame in the past. I just want to make sure I'm on the right track here!!!
