The front dive planes are attached to this metal shaft. The two white plastic fittings are glued to the hull opening.
Before gluing the plastic fitting in place, make sure that the shaft turns freely.
The shaft fittings are glued in with some Stabilit Express. Rubber bellows are then glued to the fittings with some super glue. My only leak came from a poor seal of the rubber bellow which I fixed with a nylon wire tie. I probably did not use enough superglue on it as I was trying to go easy with it to prevent it from getting into the shaft hole.
This control arm is attached to the shaft.
Here is the completed dice plane assembly. Make sure that the arm is over far enough because the battery tray is installed very close to it.
The servo is connected to the dive plane by way of this flexible control rod located near the bottom of the picture. The control rod is supported by the tube at the top of the picture.
The tube for the control rod is glued into the hull once the metal rail is clearance to let it pass. You want to mount it as far left as you can so that you will have clearance for the battery tray.
The tube is made out of a material that does not stick well to glue so make sure you glue joint completely encapsulates it or it will come loose. (ask me how I know!)
I went back after I completed the boat to make a small wedge out of scrap plastic for the servo end of the guide tube to push it more to the center. The clevis was rubbing the bracket before the modification. The wedge is buried under the glue
Here the rudder linage has been attached.
The battery tray is on the small size but I found a LiPo battery that fit perfectly. It's a thunder power 2100mAh 7.4v. It has roughly twice the duration then the recommended battery pack.
