Bob, 
I was wondering what happened to you.  I can most certainly make a trip down to give a hand if your stuck. I can take my bride down for some shopping :-)   
Email me at hankpronk at live.ca  and we can set it up for next weekend. I have been wanting to see what you doing.

 Alan, 

 Thank you for your reply.  My name is Bob Travis.  I 
 don't know how to make my name show up on my emails like 
 the rest of the group and I apologize for not signing my 
 question.  I have watched the threads for years now and I 
 met some of you at the Psubs convention in Washington this 
 last year (I was the one that no one was expecting).  But 
 for the most part, I have just watched, 
 read and attempted to learn.   

 A little background...  I started dreaming about a sub 
 in 2005.  My wife (aka.. the read head) gave me permission 
 to proceed, but of course, has occasionally put up some road 
 blocks which has delayed things a bit.  I started the 
 actual construction a little over 5 years ago.  I have 
 studied Trustworthy, Persistence and Guernsey Submarine as 
 well as snoopy and some of the other boats on the 
 site and have gained great a great bit of knowledge and 
 direction.  I have also learned an amazing amount from 
 reading the threads from the group.  

 About me...  I am the quiet one that sits in the 
 back of the class not wanting any attention. I have a huge 
 problem with putting myself out there.  I live in Eastern 
 Washington and I am building a K-350...... and, because of 
 the above, have not posted my project pictures on the 
 site.  I keep thinking that I am going to do this but I 
 just haven't taken the time (or built up the nerve).  I 
 am a pencil pusher.  I don't have a mechanical bone in 
 my body!  So some of the most basic things are very 
 difficult for me to get my arms around.  Want to negotiate 
 a $500,000 deal, I'm your guy!  Want to hook up an 
 electrical panel... Ahhhhhhh????????    I have made 
 almost all of my structural parts, have had them welded and 
 am now working on my electrical and have not a clue what I 
 am doing at this point.  I am struggling with some of the 
 most basic items (like finding the correct ampere meter) and 
 for some reason have a mental block on how to proceed.  I 
 really appreciate your response and will follow the 
 link! 

 I am at the point where the red head has told me to 
 "get that stupid thing done" and I am not going to 
 question it!  With her recent permission, I have a renewed 
 energy level and will be doing what ever possible so that I 
 am testing in August!  So with that said, I am going to be 
 asking a bunch of very basic, stupid questions!  I will do 
 my best to go back through the archives as to not bog the 
 group down with previous topics. 

 Hank... Any chance you will be making a journey to 
 Spokane any time soon??? 

 Thanks again everybody!!!  And with your help, and a 
 little luck, I will be dragging my boat to the next Psubs 
 convention on the east coats so you all can teach me how to 
 dive it! 

 Bob

 Hi, 
 not sure 
 who I am talking to, but the brushless motors put out a lot 
 less 
 electronic 
 noise, so less interferance with sensitive 
 equipment. 
 They 
 don't wear out as quickly, as they don't have 
 brushes, & you get more power  
 for the 
 same size unit. About 7 out of 8 thruster manufacturers use 
 BLDC motors. 
 There are 
 a host of cheap motors at "Hobby King" With 785 
 Watt motors for $25- 
 http://www.hobbyking.com/hobbyking/store/__522__517__Electric_Motors-45_to_50mm.html 
 You need 
 an esc (electronic speed controller ) which costs about 
 $50-. 
 The escs 
 normally work off a receiver sending them commands from the 
 remote control transmitter. 
 However 
 there are control units you can buy that are wired straight 
 to the esc. 
 I  am 
 experimenting with BLDC motors at the moment & are 
 wanting to make up a thruster.

 Is there a reason I should go with a brushless 
 motor?  I can get a 500 watt, 36 volt scooter motor for 
 about 50 bucks but brushless are harder to find and more 
 expensive.  Is there an email thread on this already?  Has 
 this been a topic of discussion in the 
 past?
