Spent a coulpe of hours on the pitch trim servo mounting. This comes as a stand alone kit from Ray Allen and is fairly simple to mount. The green primed reinforcement plate gets riveted to the port elevator skin. The servo (the black box with wires hanging out) is then bolted to two short lengths of z channel (the shiny surface in photo 2). The z channels are then riveted to the access plate, photo 3. The access plate then is screwed into the reinforcement plate via the platenuts previously riveted into it. This allows for removal, inspection & maintenance access.
