Speed controller question

[boss subfixer]

I decided a while back that I was not too happy with the performance of the USS Crockett I have so I want to totally repower it. It has a single 6 volt Dumas motor that fed into a gear set to drive the two shafts and is controlled by a Dumas mechanical speed controller. As I said performance was dismal. I have acquired two 12 volt Dumas motors that are mounted to a belt drive set up giving them a 3 to 1 ratio and I want to (if I can) use an electronic speed controller. Now for the tricky part. I have a few ESCs on hand and these are the only ones I am considering. The wife is laid off so hobby cash is as scarce as hens teeth at the moment. The big questions I have about them is will they take 12 volts and do you think they will handle the amperage from the two motors. I'm not sure what the total amperage is just yet and was hoping to call on the years of experience here. Here is what I have for information along with the esc description. I did try looking up the Novaks and the Traxxas on the company web sites but I don't think they are made any longer. Any help would be appreciated and thanks.

Novak Rooster, 100 amp, voltage input 6 or 7 cells. I'm pretty sure the amperage is good just not sure of the voltage.
Novak Hammer pro, 80 amp. Again voltage and does anyone know if it's reversible.
Futaba MC210 CB, this one has a 30 amp fuse so it's a voltage and amperage question
Dynamite power pulse. I have no info on this one.
Traxxas XL 1. again no information.

Traxxas XL-1 is rated for

Traxxas XL-1 is rated for 6 or 7 cell battery packs. (7.2 or 8.4V) I would think it would burn out on 12V.

Don,

I am certain that the futaba is rated for 7.2 volts as well

Don, it looks like you're SOL. After a Google search, it seems the only ESC that's rated for 12 volts is the Novak Hammer Pro but this one doesn't have reverse.

Skip,

I must respectfully disagree. Might

Skip,

I must respectfully disagree. Might I suggest you check out the MTroniks line. I've been using their Viper Marine in everything for the past 3 or 4 years.

6 to 12 volts, up to 40 amps, waterproof, full reverse, etc.

Jim - Read his post

Jim - Read his post again. He is stuck with the choices listed.

"I have a few ESCs on hand and these are the only ones I am considering."

And those were the only ones I was referring to. So there.

I had to make my

I had to make my own ESC. I couldn't find anything that could handle the power. Some of these ESCs are advertised or rated for hi amps but I would burn em up. It runs on 12 and 24v (DVVT). It is rated at a real 40 amps 100 v.

When the sub dives it’s running on 24 v drawing 18 + amps.

Hey Jim my friend, http://www.subcommittee.com/forum/icon_biggrin.gif

Hey Jim my friend,
If I have learned two things in my life they are.
1-Water will always find its way in.
2-Never answer a post Skip is involved in.

O, and three-Never spit into the wind!!

All three are a loosing proposition!! BD.

BTW-See you soon guys!!

Thanks for the fast replies

Thanks for the fast replies guys I knew I could count on you. I suspected as much from my choices but thought I would ask anyway. I have other boats those will work in.
Jim I have an MTronics viper 10 in my Sturgeon and your right they work great.
Carcharodon what can I say but YIKES. That's way over my head! I'm just a simple John Deere hat wearing mechanic if you know what I mean.
BD there is one more thing you should never do into the wind.

Hey Jim, Don't feel so

Hey Jim, Don't feel so bad, and they say these test aren't made to be tricky
