Starting my first build a pt sport 40 I will be use all speed master hardware and will power the boat with a neu 1527 1.5d 6s 2p thinking of useing a cc 240 speed control what do you guys think will the 240 be able to handle this setup or do i need to go with more speed control also what do you guys think on teflon liner for stuffing tube or no liner ? any advice would be appreciated will get some pic's of my build up soon hopefully I will get her done by the time the ice melts around here

[Ub Hauled]

I think you'll be stretching your luck if you use a LV ESC... I have heard of people doing it this way though...

[tth]

I personally do not use teflon. It has much less resistance on the flexcable. I also make my driveline as short as possible, but I know its not easy on a hydro. About the ESC spend a little more money and get yourself a HV speed controller. I just bought a Hydra HV240. Your setup will thank you. If you don't want to go HV try the Etti race ESC without
bec it is good up to 7s.

I second the HV controller, particularly if you're running 2P. The higher total wattage stresses any controller. I make it a practice not to run a controller within 2S of its maximum rated voltage.

Again, no teflon liner as long as you keep the cable lubed - which you have to do with the teflon anyway. Flex cable length is not as critical as CG placement and short power wires, so place the motor where you can best achieve those paramaters.

Thanks guys for the advice I am going with no liner. As far as the speed control do you guys think the HV 180 will work for me as far as the Etti speed controls go I do not know much about them how dependable are they are people having good luck with them i have used castle stuff with good results don't mind spending the extra on the HV but saving some bucks with the Etti would be nice if it's a dependable piece of gear! getting ready to mount the hardware up today got no honey do list so i can get a lot done today thanks again for the help guys

[tth]

The HV180 will definately get the job done on 6s2p and you will have room to spare. I have a Etti 150 and can say it is a great esc. The CC will give you a little more forgiveness with the voltage though.

Another possible esc :

Besides the Schulze 40.160 this is the most used heavyduty esc here.

If anyone is interested, I would be happy to help with the communication between you and the guy who makes and sells them.

Gerwin, are you certain that controller will run a Neu 1527 D wind? The Schulze 40-160 will not work reliably on any of my 1D-wind Neus; I may get one pass or lap, then the controller loses the rotor position and shuts off. The extra wire in the 1.5D motor the OP intends to use may be better, but I'd hate to buy a costly controller that does not work with my motor.

Jay,

Is this the 40/160 with new software V16?

[Gerwin Brommer]

@ Jay,

I've never heard of any problems with this esc, working on 2poles, 4 poles, etc etc.

I will mail the people from Modellbauregler.de and ask them if they can assure
the esc will work with Neu's.
BTW, what's the exact setup ? cells, prop ?

[Fluid]

It doesn't matter what the number of poles or the setup is - the Neu 1D winds have such a low resistance/impedence that the Schulze ESCs have trouble "seeing" the rotor position consistently. Most of us over here who run them have the same problems, so it is not an isolated issue.

Examples in a SAW cat running in the 80s:

4S2P/9000mAh - 1521/1D - x450 through x457

6S2P/9000mAh - 1527/1D - x445 through x452

A Castle 240 had no problems running the 4S setups.

[Fluid]

Is this the 40/160 with new software V16?
Yes, and Schulze apparently has no plans to make it work with the smaller Neus. There is no problem with the big Neu 2215 or 2230 - but those motors have a lot more wire than the 1500s do, plus they are 'Y' winds not 'D' winds.

[Gerwin Brommer]

Mail is sent to Micha and Denis, the designers.
As soon as I get a reply, i'll let you know..

[Gerwin Brommer]

Jay, Denis replied :

he likes to get more info on the Neu's. They are not very familiar with them in Germany

[Fluid]

Gerwin, some technical information is available on the Neu and the Castle websites. Neu also answers e-mail, if you know exactly what he wants to know you could ask the Neu techs.

http://www.neumotors.com/Site/1500_series_.html

http://www.castlecreations.com/products/neumotors/nm1500.html

I find it strange he is not familiar with them, they are winning international airplane competitions.

.

[Gerwin Brommer]

Yep, but Micha and Denis are more into boats.
This afternoon i already mailed him the datasheet of the 15 series.
He asked what the diff. is between D and Y winds :rofl:

[teetriple]

Thanks guys for all the input on speed comptrollers I am going with HV 180 my local hobby shop has some in stock for a really good price got my hardware mounted just waiting on my motor and motor mounts to get here then i can get them in so i can do the stuffing tube hopefully I will get some pic's up soon having problem loading pic's to my computer

[Gerwin Brommer]

Jay.

Modellbauregler has sent a reply.
How can I get in contact with you ?
(as i can't send PM to you)

Gerwin

[Ub Hauled]

Gerwin, can you post the shops reply here as well please?
I'd like to hear what they had to say.
thanks

[Gerwin Brommer]

In short :

uptill now they never had an issue with their esc "not keeping up with the motor"
They never had a motor on it like a Neu 1D
Only way to test it : test it :biggrin:
They offered me : buy one, with full, 100%, money-back-garantee if the esc can't handle the motor.

It makes no sense if I order one, have it shipped to me and send it to Jay (if he really wants to test one).
So I asked them if they are willing to ship to Jay, if he wants to buy one with full money-back-garantee.

[Ub Hauled]

Very cool Gerwin, thanks for all the translations.
I am sure that all the non-germans on this site appreciate it.

[Ub Hauled]

It doesn't matter what the number of poles or the setup is - the Neu 1D winds have such a low resistance/impedence that the Schulze ESCs have trouble "seeing" the rotor position consistently.


Jay, isn't that something that a higher PWM setting should fix?

[Gerwin Brommer]

Jay, they are more than happy to send a AS26/150 straight to your adress.
They also honestly told they really don't know if the esc. will work with such low imp. Neus.

[Fluid]

Jay, isn't that something that a higher PWM setting should fix?

Nope, you saw the results in LA. Neither Brian or I can get the 40-160 to work with the 1D Neus, and Schulze isn't interesed - apparently - in making it work. Can't say I blame them, the market would be pretty small, and they say that selling to Americans is a hassle anyway.....

Gerwin, if they are interested I'd be happy to test for them. We really do need an option for mid-voltage Neu-powered SAW/fast oval boats.

Mighty Schulze's Achilles ankle...
I knew there was a reason not to buy one LOL

This is a "special case" and should not steer anyone away for Schulze esc's.. They are worth there weight in gold!! I have yet to see or test a esc that can truely compare to a Schulze! I am sure Jay would agree..:tiphat:

[Ub Hauled]

I know, I know... I just had to have my fun...
;)

[teetriple]

Well finally got pic's to load to my computer here they are not alot done still waiting on some more parts

[longballlumber]

Hey T,

Looks good man! I think your really like this boat.

Mike

[teetriple]

Well this build is going slow but hopefully it will be done for the first club race got some carbon fiber laid in the hull today weather was finally nice here in Mich 55 degrees o boy even got to get my u-l1 in the water and do some testing:buttrock:

[EPower]

That looks like a KB45XL :smile:

[teetriple]

No it's a Nemesis 9xl just using it for mock up for motor location waiting on neu 1527 on order

[teetriple]

Well it took me almost 2 years but it's done now ran it in the first club race of the year today and ran pretty well I am running her on 1527 1.5d HV180 speedo & 6s 2p I would guess she was running a solid 60 mph thats just a just guess but others seem to agree maybe a little test and tuning I could see 70

[teetriple]

One more pic

[Rumdog]

What prop? You should see 70 with that setup for sure!

[Rumdog]

Tat is one awesome looking hydro there bud!

[teetriple]

x 452

[teetriple]

Thanks it's my first build

[BHChieftain]

Wow... nice job!!!
-Chief

[m4a1usr]

Thanks it's my first build

Your hooked! And only good things can come of that. Nice looking build!
