This is my 59" SV43 from Central RC Marine. There will be an attempt to power up the massive

TP100 motor this week at the pond. Here are the Specs.

Turnigy Monster 2000 ESC
10s 2p lipo
TP Power 100MM Brushless inrunner (540 KV)
Peter Z coupler bored out to 12MM
X467 octura prop
Old school Octura twin rudder.

Whats up beautiful paint job! I'm not sure she'll go too quick as the rpm comes out to 19,980 but you can probably turn any prop you want with that boat. 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.

That is a beauty

If you want to go 50 mph with a 2 foot boat, U spin a little prop 30 000. If you want 50 mph with 5 foot gas hull, You need 18 to 20,000
loaded RPM and a huge prop. I have that. Oh, by the way, who said i needed advice.LOL:moon:

The paint turned out pretty good. Needs some graphics though. Thanks!

Or you could run twins spinning 30K loaded and reasonable props and run faster then 50 mph....:cool2: More then one want to move this hull. Interesting choice on the controller, have you used one before? I would like to see some video of this one. Looks good. :thumbup1:

[Steakhouse]

That would be super cool too. Like 2 1527 Neu's or 2 5692 leopards.

Or 2 Proteus 524-3T motors...:smile:

How about a 5ft boat going 80mph? I have that. A few actually. Good luck with your build.

Um advise u do need that esc will toast itself on the squeeze of the trigger. There isn't a ecs out there that can run that motor safely.I am having a crazy hard time getting a sufficient esc for a set of lehner 3040's with only amp spikes of 400 plus but you will have almost or more than double that amp draw

[jkr]

Does CRC makes epoxy hulls?

Beauty!

[Chrisg81983]

Pretty sure only polyester

[Jason4636]

I wish you luck on your run. But I would have run an esc with datalogging. And run a baby sized prop to see what the amp draw would be. Starting out with a 70mm prop and only a 200amp esc. I hope it will survive the first hit of the throttle. And if the esc goes up in smoke, I hope it don't take the motor with it. Get some video of the maiden run. I wish you luck

Im going to have a quiz Thurs. on basic electric principles. You are going to need a tutor.

Take your 3040 lehners and trade them for a case of beer and a hooker. Purpose built SAW/Hydro motors. Nothing less, nothing more.
You can have a much friendlier setup with long cans such as 1527 Neu, 2250/80 lehner, and still have 80 mph when u want it. Too small? Well then the 3040 def has no purpose in your boat. 3060, 3080, 2230 neu TP5850. Torque is your friend!

The motor/prop combo I have is equivalent to putting an Octura 437 on the end of your 3040.:wink:

In reality, i could have an even better sport setup with an x665/3 on 8s. What a motor can pull and what a motor can see are 2 very different scenarios.

[iridebikes247]

Oh boy....Chris and I run together his hpr 115 reaches 105 mph and his hpr 135 faster. I think you should visit hpr's website and take a lot at the motors used in record setting catamarans. Not in hydros but in 25lb 12s1p boats. Consistent runs with all electronics under 105 degrees....I'm not sure what we're missing here. No one fast runs over an x470 reduced to 460. I would post links to videos but there are so many.

As for running low kv high voltage big props, looks good on paper but runs horribly over 70. I know because I used to run big props low kv. You're after 50mph once you step into the realm of 80mph+ or maybe I should say 100+ then you can tell the hpr guys how they've built their record setting 53" SAW cats incorrectly.

[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

[Steakhouse]

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.

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.

[B Neal]

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 !!!

[nata2run]

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.:tiphat:

[rscheffer]

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.

My last sort of quick boat.

43 challenger mono, 2215 BAM on 8s

about 65 MPH

[Jason4636]

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.
