how would this motor do in a 27" boat hull on 12 5000 mah sub c's?

what is the max amp draw? or would the other puller motor work better?

Couldn't tell you, I have never run boats and I know absolutely nothing about them.

Need something for a boat?

What about brushless? Wouldn't that be better for higher power stuff? I'm sure the Cobalt Puller would haul ass in a boat, but don't have the smarts to know where to start for prop and such.

As long as you can prop a motor that spins 1800kv and likes to run around 12 to 14v max then it should work good.

so 2- 7.4 30C 5000mah lipos would be pushing the envelope?

Yeah, pushing it. But if you are racing you might not care so much about pushing it.

I think they don't like more than around 35 amps continuous on 12 cells. Bursting you could hit 80 safely I would fully guess. The brushes may even let through 100 amps or more. Rm is .047 ohm.

i think you will kill the Cobalt Pullers within the first run
Plettenberg HP 290/20/7 and Octura X442 will fit for a 12 cell mono

Ive got the plett in it now and frankly they are highly overrated, and I love to try new junk. with the puller I will be able to throw a x645 without any issue. I have made several water cooling jackets for them so heat is not a big issue

Hi, I'm from Italy and I would like to get 2 Cobalt but when I checkout I get no shipping methods for my Country.

Do You ship internationally ? If yes, how can I get the shipping methods and price ?

You can also contact me at andrea.zinno@gmail.com

Regards, Andrea.

JRH,
I'm running a Sidewinder and 8 cell NIMH pakcs with 16ga wire. I've been running 55t and 45t lathe motors and am ready for an upgrade but I want to make sure I'm not going to fry my ESC or batts.


What do you think?
