Re: [PSUBS-MAILIST] psub convention in Raystown

Hi out there,
   I have some questions on my new k-250
       I have been reading all your emails and am now looking forward to 
putting my k-250 in the lake for a trial spin in a couple of weeks, but a 
couple of things are bothering me.
         first issue is the props, the sun has done its damage to the 
plastic and I need new ones. They look like old minnkota trolling motor 
props. is that a possibility? Do I worry about prop pitch ?
        second. how much air pressure do I put in the aqualung for the 
fore, aft, and main ballast tanks? Can I use a regular air compressor to 
fill it? Is one aqua lung enough (only have one) for a test dive to about 25 
feet down?
       third. do I fill the main ballast tank (my seat is this tank) for 
neutral bouyency?
      fourth. Is RTV used for the port glass gaskets? (it looks like red 
rtv) and is rtv a problem?
     fifth,  an air line has come apart at a fitting, is stainless fittings 
and tubing a problem instead of using copper for the air lines? Copper was 
used  in the sub but the stainless I have is for higher pressures.( 
dissimiler metel issues?)
      and last but not least , the batteries. What kind? will  marine 
batteries be alright and do I have to use the hydrogen caps ( batteries are 
sealed and dont usually accept the screw in caps)  by the way there is a 
battery box is a extremly well built and is sealed.

  One more question, is there really going to be a convention in michagan? 
Upper ? lower? but no matter it would be close enough coming from minnesota 
towing my lil sub for me to want to be there.
Thank you for your time and  the wonderful stories that I have been reading 
on the psub site, without you guys guys like me would be making terrible 
dangerous mistakes.

                                                                        Rob
