I know the recommendation is 8mm servos but I just got my Sessanta and the Frsky 5651 I bought for the tail do not fit in the tail opening, they are too thick and will go in at the fwd edge of the opening but you can’t move them aft. Do I grind off some carbon of the fuse back there or get thinner servos? Plus there’s no way to get two servos back there unless one is mounted fwd never to be seen again - is that the design intent? Any help appreciated….
