Well if you build this sub, take one of the props to the hobby shop and match the shaft size for beginners, drill out the shaft support for the shaft size and then drill the hole
into the hull of the uboat. USE A DRIMEL TOOL! now for the pressure hull, some of you here know how to make one, mine is very crude but it works well for this application.
Now somebody asked about the wet motor, make sure you break the motor in submerged in a cup of water, for some reason this breaks in the motor and so far my motor
has not seized. the Servos are easy to do, buy some tool dip from your local hardware store(Lowes) and dip the servo as far as you can. get o-rings and get the size that your servo gear housing is. smear some silicone grease on the oring aand then put the arm down on the gear.. your servo is now water proof.

My Uboat does have styrofoam inside it to give it some floation , I do not believe the WTC alone will let her float but I'm going to make sure the next version will have all the corrections to construction that the first model had. My biggest change will be the motor setup, I will not use a gearbox and a single motor but use two motors and my steering linkage will be made slightly different.

not much change from there, easy to make but if you try to make it complicated, your going to find out you don't have a lot of room but atleast my front diving planes do
work and should aid in the diving efforts. :-) I will find out soon enough when I go to the pond or large swimming pool.
