Newbie with a boat pursuit

[golfito]

Hello, I'm building my first rc boat. I have several cars rc brushless systems.
The boats are new to me. I ask your help to see if the setup I want is correct. And if you need something more.
I have available:
5s batteries. (blue lipo, 5000ma/4000ma, 30c and 60c burst)
Hking external Bec (my truggys use 1 / 8)
4mm Bullet Connectors.
I think of buying:
Seaking 180th / 180th Turnigy
Turnigy 4082 motor / 4082 leopard. Both of 1500 kv.
4050 Leopard Jacket Water Engine
Water cooled motor and adjustable mount for 4074 & 4082 Leopard
Some glue to reinforce the support of the motor bracket. What is your advice?
front of the boat filled with foam.
AquaCraft Speed Grease by Grim Racer.
Use tape to seal the top cover? or placed a rubber seal and screw cap set?
With this setup you need to add extra cooling intakes?
and finally:
I have no idea propellers buy.
I would like the boat is fast.
Sorry for so many questions.
I speak Spanish and I hope you understand what I might write. Greetings and congratulations for the excellent forum.
Thanks, Hernan.

Sounds like you have some good equipment in mind. The Turnigy/Seaking 180 is a great choice for an ESC. The 4082 1500 kv motors are quite enough and should give you speed into the 50 mph range spinning a large prop, something in the x448 range would do well on the 5s you plan on. I'd run two of the 4000 mah batts in parallel on each side of the motor for balance purposes and some good runtime.

Thanks for helping!
I had not thought to parallel the batteries. I thought it was too much weight. It is a very good option for increasing autonomy. As you have not received the pot. I have no idea of the availability of places for the batteries.
Look for a x448 and put it in my shopping cart.
All help is welcome, thanks!

After more than 20Day have placed an order recently came out of the boat hking on 10/06/11 ... took too long for shipping. I'm still preparing things for the boat pursuit: Disassemble the drive, adds two more water peaks to use another bigger cooling channel, we add to the 3 1000uF capacitors and other 2 of 2200uF 35v and 35v in parallel to increase the capacity. Dissipating a lot of fat between the plate and heatsink.
I added an external bec say because the internal burns 6s. I lack all protect against water ... and see me as I work out.
preparing the sink:

I could not get the rotor of force with the magnets:

That I have not weighed, but it is a brick:

This should go in the boat and hopefully stay floating in the water ... -?

That engine kicks like a horse ... umm, a truggy with 6s must be nice.
Sorry for my English, I try to make myself understood.

I wouldn't use 4mm bullets. I would go at least 5.5mm or higher. I am running 6.5mm bullets on my leopard motors. Those 4mm won't cut it.... IMHO

Yes you should use. 6-6.5 mm bullets.
I use them too and for extra contactivity i use solder with 4% silver.
Make a no-spark resistor and save your capasitors.
Waterproof the stinger with the hull with silicon tube.
Τhat thing will fly!

[golfito]

Thanks!
Waterproof the stinger With The hull with silicon tube. What is it about that?
I'm using 4 mm bullet connectors. But do not forget that batteries are in parallel. I estimate the current flowing through each pair of connectors will be half. If my assumption is true, in this way would have an even greater margin of safety.
If you would a single battery if you would use larger connectors. I hope I am not mistaken, I have several connectors 6mm in my bag just in case.
Greetings.

Doesn't matter if your running parallel if your running 4mm on the motor/esc connection they will fail. I still wouldn't recommend 4mm on your battery connections either. If you have 6mm in your bag use them!

The one thing I find missing what hull? or am I getting old! Welcome to this forum.

I'm using 4mm and have not had a problem yet with my 40C 2S'S. The issue usually is in the solder or crimp in these. Also if you use 10 ga. wire it will help also but the weak point is always going to be how you solder or crimp the parallel setup. I slice the wire insulation (not cutting the strands) and run the strands into the hole you make in the strands. Then solder the connection. I have seen people even braid it lol. Then double heat shrink the connection. Works very well :). Also a great place to get extra 4mm bananas is Radio Shack as they use the rubberized sleeves that move up and down to make sure you don't have any bare spots. I would like to find some super tigers but they are OOS everywhere I go and overpriced. :) So as long as you are a good solderer and stay under 15V I think you'll be OK. Just test things out and check on your boat every two min your first run. Which you should do no matter what on any FE. Even Traxxas RTR Spartans are melting because people don't test things out.

I can say that with the 6mm bullets your current flow with lower resistance.
Lower resistance less heat and more power to the motor.
I use orings to the stinger and i waterproof it completely.
For the cover i use window sealing foam strip.

[MR2NR]

I agree that the bigger connection will net lower resistance but I wouldn't buy new connections if what you have on hand will work fine.

Thank you very much for the welcome all guests!
The hull is en route from Hong Kong. It took a long time you send it. I'm very impatient!.

[golfito]

I want to thank everyone for their support.

I parts are coming, also a 4074 to 2000kv and a t-180th in reserve.
Also quanum telemetry system.
I got a liquid latex to cover the electronics. That can be effective in case.
greetings!

LOL................still no answer, but i assumed it was a Pursuit 32" based on the title...................hmmm.
