first of all im running the aquacraft system in my cat..... i ran 14 cells on it last night and it was really really fast..... but it has horrible glitching problems.....doesnt on 12 though.....any answers

also i still cant keep water from entering my boat.....its deff commin in through the stuffing tube...... i have tried everything......any suggestions

[avengersteve]

is it comming in at the transom? i put a bunch of silicone around mine, and use a bunch of water proof greese on the shaft. helped a lot.. i run 15 cells in my sv with no problems... mayber your reciever?

I say BEC.. Are you running BEC?

[Steven Vaccaro]

I say BEC.. Are you running BEC?

I second that. I just heard from a customer that AquaCraft told them the bec cant handle 14 cells. I will be updating the site to say this.

I ran the Llumar all weekend on 14 cells with no problems,,,might be my Spektrum radio that helps .

I am board with Doby. I run 14 every time I am out. My Spektrum system seems to have no problem.

BEC

Is there something more than a weight advantage to running a Battery Elimination Circuit? I was under the impression that it was bad to use the BEC.

[hammertime]

im not sure what a bec is???

[Drunken Pirate]

Hammer,

I am as noob as a noob can be with RC Boating and RC equipment. So don't blast me to hard if I get this wrong but I have looked into it a bit.

BEC = Battery Eliminator Circuit. Your ESC provides this functionality and it allows you to power your radio receiver using your esc/motor power source. So with a BEC you can eliminate the battery power source just for the receiver.

It has uses outside RC: http://en.wikipedia.org/wiki/Battery_Eliminator_Circuit (wikipedia)

oic so if i were to add the seperate aa battery pack to the receiver would this help??

Hammer,

I am so not the guy to answer this. I am sure someone else here familiar with your model can point out the specifics. But I think you have to do a couple of things.

1. Somehow turn off the BEC functionality. If it is with your ESC then there must be something you can do to regulate it.

2. Hook up a battery pack according the the receivers manufacturers specifications to the receiver, hopefully with a switch in between.

3. Depending on the weight and what you do with the boat I am guessing you might have to place the added batteries for the receiver to stabilize the boat on the correct center of gravity (or this might not matter at all).

OR

4. Buy an ESC with a BEC that can handle that many cells.

Please correct me if I am wrong.

It might be tedious, but do you mind listing what you have done to the stuffing tube, and can you post some pictures detailing the area?

You might find more help there that way.

DP...

[hammertime]

yes i will.... im goin to do a few things to see if it doesnt work ill post thanx for your help much appreciated

Re: water
if you're keeping the boat on plane there should be no leak. think what I would do is; check to see if the water is coming in through the tube or around it. if you have access to a bathtub this should be easy. step 1) pull the prop shaft step 2) fill the inboard end of the tube with petroleum jelly step 3) with hatch off put the boat in the water 4) see where the water is coming in. if you don't find any water coming in either you are correct that its coming up the tube or you have a cooling system leak.
