atomic 58 inch catamaran motor question

[Brushless55]

for you guys looking to put big motor in this hull
http://www.offshoreelectrics.com/pro...prod=ose-80076
a simple 750ish kv on 8s with a gas size prop would make for a really good runner!

there is a guy on youtube who converted the gas version and used a 540kv on 10s with the stock gas prop and that sucker moved
way faster than the stock gas motor ever could

Hello, just got my ARC 58, is amazing.
Any tips for me? I just put some positive angle to the strut and cavitates alot.

Thanks

I installed a Leopard 5692 - 1090KV last night with a water jacket. I used the existing side mounts from the motor mount. I bought a piece of aluminum from Lowes to make a new front plat for the motor to attach to. I will post pictures later. I had to buy a new coupler and replace the hose for the water to exit from the motor. The line in was the right size in length. Will run it on two 4S packs.

I also have a New Leopard 5692 - 730KV for sale.

Please send the pictures, sound very good what ESC are you planning to use?
What is the difference of using the same kv motor but with longer ones 5674, 5692, 5698 or 56110?
Here is my vid with the stock ARC http://www.youtube.com/watch?v=ffcq3VfA3nQ

The one line is not connected for the water discharge. The original bolts that secured the side brackets cannot be used because they will prevent the motor to fit with the water jacket. Using the original side brackets will allow you to adjust the pitch. I had to make a front plate. It was not hard, took my time to make sure the holes were in the correct location. I bought new screws to secure the motor to the plate. Then solder the new bullets onto the ESC. On the second try I had the motor wires correct for rotation. Hopefully I will be at the lake on Thursday to find out how everything will work.

What make is that 200a esc ?
That motor will pull some high amps from it on 8s,
Also what prop will you be starting with ?

[Finest Racing]

The ESC is a no name. I have been using them for awhile without any problems. I think the current ESC will be enough for this setup. Hope to find out on Thursday.
I will try the stock prop and a prop that is the next size up that I am currently using. I will be watching the temps and be using the GPS to know if the props are working.

Waiting to hear how the setup works

[Finest Racing]

I am waiting to go. LOL Today was the day to go, I had to decorate the house for Christmas. Spoke to my friend about a date to go run. Looks Like December 1. He is off on Sundays and Thursdays. I am excited to see this thing run. Curious to know what MPH. Between myself, Damen and Ken we all have different predictions. Ken is thinking maybe 70mph. Damen said 60mph and I think I will see 65mph.

Hi,
You should post some video's of your in the video's pictures threads.

The difference is the motors can sizes and lengths will give more torque and should be more efficient,
Than the stock motor in that size of a hull.

So it should run better and faster and cooler to in the long run,
But only If the boat is setup right and running free and airs out good.

And if it is not setup right it well not be efficient,
It well run hot with low speeds and will have short run times to because of it.

I also have 4s for the new setup. I will do the same balance test as I did with the old setup. The way I did the setup on the old setup worked out very well, everything was very cool after a 4/5 minute run.

[lenny]

You will be running that 5692 1090kv motor on 4s ?
What is that no name esc rated at 4s, 6s, 8s, 12s. ?

[Finest Racing]

I will be running two 4s to equal 8s total.
I will need to check on the ESC rating.

[lenny]

If I where you,
I would not be worried about the speeds at this time.

But I would be worried about that 200a no name esc going up in smoke and everything else in the hull to,
especially If you push that setup and it is not trimmed out right yet.

Is this the no name esc you have in the boat now and you plan on running it on 8s ?
It is rated at 6s tops.

Yep I think that would be really really good idea to do,

JFC before you three stooges blow your self's up.
