<div>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. </div>
<div> </div>
<div>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. </div>
<div> </div>
<div>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!</div>
<div> </div>
<div>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.</div>
<div> </div>
<div>Hank... Any chance you will be making a journey to Spokane any time soon???</div>
<div> </div>
<div>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!</div>

<div dir="ltr"><span>Hi,</span></div>
<div dir="ltr"><span>not sure who I am talking to, but the brushless motors put out a lot less</span></div>
<div dir="ltr"><span>electronic noise, so less interferance with sensitive equipment.</span></div>
<div dir="ltr"><span>They don't wear out as quickly, as they don't have brushes, & you get more power </span></div>
<div dir="ltr"><span>for the same size unit. About 7 out of 8 thruster manufacturers use BLDC motors.</span></div>
<div dir="ltr"><span>There are a host of cheap motors at "Hobby King" With 785 Watt motors for $25-</span></div>

<div dir="ltr"><span>You need an esc (electronic speed controller ) which costs about $50-.</span></div>
<div dir="ltr"><span>The escs normally work off a receiver sending them commands from the remote control transmitter.</span></div>
<div dir="ltr"><span>However there are control units you can buy that are wired straight to the esc.</span></div>
<div dir="ltr"><span>I am experimenting with BLDC motors at the moment & are wanting to make up a thruster.</span></div>
