After completing the motor installation I proceeded with installing the rudders. I now have the rudders in place. I put some polystyrene in between the rudder shafts to make them more stable. Then I secured it all by putting a layer of stabilit express on top. See pictures below.
The next thing will be to get the rudder servo installed.
The connectors for the battery arrived Thursday, so now I believe I have everything I need to complete the RC installation. I made a charge cable and the connecting cable for the boat.
Have a look at the pictures:
