All I need now is a carbon fiber plate. I can glue wooden anchors to the inside of the rails the load them with treaded inserts. Then I can remove or insert the tray easily. The tray will give me a nice long platform that will allow me to adjust the battery forward or aft for the optimal cg. Depending on the cell configuration some cell may have to sit out side the rails so I may glue in some secondary battery trays outside the rails we will have to see how that goes. Some times you change the approach as you build the boat. It depends on what is thrown at you. The prop on the boat is a AB x455 ground to 52mm. Anytime you do that you increase the aspect ratio so it may be around 1.8. I envision the pushrod for power trim exits directly above the stinger in between its mounts. To have the alignment I may have to print some type of capstan behind the servo. It can run with push pull cables turned perpendicular to the deck to feed a vertically mounted push and pull capstan that also push rodded to the trim. The entire stinger could pivot if you went with a square drive flex setup with a prop shaft and ferrule set up through the stinger. the log would float at the nose of the stinger. It can be done that way . You really would need to load the stinger with some type of high wear sleeve or busing at the pivot point because over time the Aluminum will break down mechanically as a bearing surface.
The servo could have just been mounted on its side but I wanted some visual uniformity there instead then deal with the necessary linkage to make it work like I envision.
