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

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

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

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.

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.

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.

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