OUTERLIMITS SV 43 Build

[Chrisg81983]

Oh boy I love people like this let him learn the hard way. You can run your gasser props on it lets see what happens. 3040 = no good thats why one the fastest speeds with same setup as mine is 137.4 with no prop much bigger than a 57. Hey maybe he should try these motors next at 20k rpm and a 100 mm prop. Obviously you know so much more so do what u want and have fun but best of luck and for the record the 2280 is at the safe limits of itself at around 100 -105 mph in a HPR 135. others and I want more and achieved more than that all day long. So use that motor u have as a paper weight until there is an esc that can run it at even 75% of what it is capable of. Please post your maiden actually any run u have over 60 mph so I can say told u so

Read what i wrote again. Then read it again. I'm not building a SAW boat. Chris was informing me that "my" motor setup won't work because my motor is going to pull 400 amps. He is comparing his SAW boat to my grossly overpowered sport boat. If I put 2 of these monster motors in a 10 foot Mystic on 12S 4P with 75mm props, it can and will pull 400 amps. My boat is a moped with a hyabusa motor. Defending your friends acomplishments doesnt change the fact that he said something grossly inaccurate.

Quote "I'd probably take advice from gas guys on boat setup instead as they'll be of better help none of us run props over 70mm."

Head this advice, atleast a fire extinguisher will be close by

Yeah take that try that on for size

Let me be more specific. I thought u said something stupid because you assumed i was building an 90 mph mono. I implied that you were stupid for running 3040's because i assumed you had a sport boat amp problem. Assumption is the mother of all F#$% ups. Lets squash this now.

Hey Meat
Not sure if you seeing the small picture here....

It has nothing to do with top speed, it is the drag of a mono and the amount current required to pull the queen mary prop to a speed where drag become less of a current / heat killer.

With a 470 prop at 25mph you are in a smoked steakhouse.

Just to be very clear I knew from beginning this is not a saw build. Sport or saw this setup is a very hard setup to run efficiently. No hard feeling buddy !!!

1.21 "jigawatts" MARTY McFly style lol on the angle of the motor itself

I sorry. I didnt mean to come off like a snot. I'm just trying to balance on a high wire between the torque of the motor and minimum Amp
draw. And my wife is being a bitch.

That motor will be a killer only 2x10 s5000 mah ? 200 a controler? Not to mention only a 1/4 flex shaft that will break if you put some power on it.
I have some experience with a 3080 lehner and that didn'n have max 24 kw by far.
Steal wire with a minimum of 3,5 minimum wil be more like it
3060 lehner and 3 mm steal wire works perfect, even better than 1/4 flex shafts.

The controller will burn with a gas prop on it for sure, because there is no real controler who can handle its full yet.
A german Modellbaupirate is handeling that problem and should be delivering controlers for these motors in the near future.
Because he also is in tending to use and sell these motors.

Give him a email .
the only 540 kv is no problem 18000 rpm is more than sufficient with the right prop.
I am building a simular hull from andy brusher from Berlin. Its his sv43 1,7 meter mono .
I am building it with two tp5850-600 kv engines on 2x10s per motor so 4x10s5000 mah total. Swoard fish 300a controlers
This setup works fine with x470 octura props as a French man has done it already. Driving time is aprox 6 min with these props.

No its not lightning fast but 90 kmh is more than sufficient for these scale like hulls and 17 kg ore a little more ready to run weight.

So for that reason for sur a max 24 kw tp will kill esc's. As you need two300 a controles to safely operate two max 12 kw 5850 tp motors
My etti220 hv pro esc ( wich i use in other models) will handle my 600 5850 tp's but will be on there limmit , so i wil have to buy a pair of 330 a esc.

Did you run your SV this weekend? Got any video?

[Steakhouse]

I finished the build but ran out of time this week. I'll keep you posted.
