That's weird, try again and refresh....

This is crazy, i cant find your vid, it wont come up by clicking on it and its NOT in your channel, I even searched for the EXACT title "RC boat 3s test"................nothing!!

Just ran mine on 3s video tonight. It's beyond fast now

[masonis1]

I'd like to know wht he is running because I couldn't find motors that would fit in stock locations and use original hardware.

[Make-a-Wake]

There is a guy that runs a similar boat, its some NQD, he has the stock drivelines, 2 brushless motors, and a center rudder with servo, its on youtube, i'll look tonite.............it runs well!

[masonis1]

Get a brushed ESC that can handle the two motors easily so you dont have to water cool it. Run the motors off of the one ESC counter rotating the props by wiring one backwards, add a center rudder and a servo and presto!

I don't really know whether he wants to go faster, e more reliable, or just be lipo power...

[masonis1]

2s would be slower?! I know it's only 7.4v compared to 8.4v, but I thought it would be faster cuz it's lipo compared to NiMH. In that case,

1. What do you think is the fastest battery this boat could handle stock? 7cell Nimh? 8 cell nimh? 9 cell nimh? 3s lipo?

2. I understand twin brushless being more expensive and complex, but why would it be too heavy? Do brushless motors weigh a lot more than brushed? I thought brushless was supposed to be a lot more powerful/faster? Would it require two ESC's? Besides, lipos are a lot lighter than nimh, so that would help compensate with weight, correct? Couldn't you just steer it the same way as stock? Or just put a rudder in between the two props?

3. Would it be possible to use bigger props on the stock boat without burning anything?

Honestly, I am not really interested in doing a single brushless setup on this boat. I want to keep it twin. I like the twin motors. I think it's cool!

It's voltage not type. Voltage! Lipos just put power to better use to say, they give more power throughout the cycle.

It's too much weight because you don't want the Same size motors as stock, you need to remove the old receiver an esc and then make new motor mounts or buy them, it's just more weight to go faster, also tere is no way, I FOUND, to steer usin throttle. Just can't happen after market.

Bigger props on the stock drive line is a no, there isn't a locknut to hold props on an they don't sell any bigger props.

If you get a flex drive, you can get a drive dog and use different props.

Twin motors may be cooler, but in all seriousness, you don't need more than one on this. It actually will be faster single!

Do a conversion like mine except do some stuff better and learn from my mistakes.

Thx for the replies, guys. Altho, u all kind of drive me crazy because you rarely answer most or all of my questions.

1. So, a 2s 5000mah 30c lipo with a low voltage alarm would probably work well in the stock Musculus?

2. Would a 2s lipo likely be faster than 7cell NiMH?

3. What about keeping it twin motor with no rudder (or possibly with a rudder), just upgrading to brushless, ESC, water cooled, and 2.4ghz? Would twin brushless still work well?

Ok 1, 7.4 would be slower than 8.4 volts. So a 2s wouldn't be faster, actually slower. Might have more power but I really doubt a higher top speed.

A 2s would e safer because of a lower voltage and woul have more power than the 7.2 but it will be far more danerous if you run past the LVC.

I tried twin brushless, for one its more expensive, too heavy, no way to steer it like the old system, need more battery, it's easier I go single motor with a rudder. Instead of two motors and esc you only need one of each.

I was using exceed out runners my first try, twins, and it didn't do it. Even those small out runners with 35a esc were too heavy!!!

Yeah that lipo didn't give near enough power. It was a 3s but tht seriously was the last run on that lipo. It was a puffed rhino 1050mah 3s

I will try getting some running video either tomorrow or this weekend. I'm trying to start up my build to help you a little. Check it out to see my current setup.

Here's Masons, he's goin easy on it, runs well:

Hello, everyone. I bought one of these boats. It's called a Balaenoptera Musculus. http://www.handhelditems.com/2334-ba...t-p-54897.html It's a very fun simple toy grade boat. I upgraded the battery from a 6cell 1800mah NiMh to a 7cell 5000mah, and it works well, but I have several questions for the experts.

1. Would I be able to use a 2s lipo in this boat?

2. Would 2s lipo likely be faster than 7cell NiMH?

3. If I use a 2s 5000mah lipo for example, what minimum C rating should I use?

4. Where could I get information and/or help converting this boat to twin brushless, ESC, 2.4ghz, and water cooled?

5. If needed, is there someone I could pay to convert it for me since I am not very handy?

Thx in advance for all responses!

Go single flex driven brushless
