1515 Neu motor

[EPower]

here is a question for the Neu gurus
I have a 33 in Mhz Lizard i want to run a 4s 2p setup in it i have Etti 150 Race Esc 4S/5300 mAh/25C lipos, witch 1515 Neu motor is suitable for it 1Y or 1.5D i have been sent some info but i.m more confused that i was beforeThis is not a race boat just something to blast around the pond
This is the info i got
Adrian
In most boats racing a 300m course a 1515/1Y is the setup of choice drawing
about 130 amps on 4S TP V2 5000s or similar; Esc's are Hydra 120 or 240
usually props are worked 42mm diam - speeds are 80+ if you use a higher
rated esc and twin packs you can run up to Octura M447 or simply enjoy
runtimes longer than 2 minutes

The 1515/1.5D is not suitable for a 4S mono - too many rpm - which means
high amps 150-200 and ESC to match - OK if you run two packs and the higher
power esc and watch all the temps very carefully - 42mm prop is close to the
limit

The brand and generation of 25C will make a big difference especially with
the 1.5D

Thanks

I am not a guru, but from my experience with the NEUs is that they are very powerful and you don't need to have extremely high rpm. I agree with above that the 1515/1.5D (2700 kv) is too high and on 4s you might end up in burning the esc expecially in sports running start-stop-full -stop etc...
The 1Y is very widely used-tested and recommend it with a 42mm prop, and if you want to be safer go for a 1515/2D (2050kv) but with a slightly bigger prop. abt 45mm for speed or 42 for more time

The 1515/1Y is a commonly used RACE motor for hydros. IMO it is not at all suitable for a big sport mono. The 1515/2D or 1521/1.5D are more suitable but they are still quite powerful for sport running. In spite of its slightly higher cost I believe that the 1521/1.5D would work better for you. Regardless of which Neu motor you choose, you'll need good cells. I recommend 2P if you can afford them, but if you limit prop size and run time you can get along with 1P.

dang, 'nother double post

Hey, hope I can jump in and share in the Neu club.
I am setting up my DF33 exactly as Jay recommends 1521/1.5D, Etti 150 ESC, 4S2P Flighpower 5000mah 25C batts and an X447/3 prop - sound too big a prop?

I have question: 1515/1D motor - 29" hydro, 2S, x6/442 prop? or bigger? OK with HM 200amp ESC?

What's the difference between D and Y (aside from different KV)?

Hi i'm not 100% sure but i think the D and Y have something to do with the windings of the motor

[Jesse J]

maybe different thickness wire, so it give you two sets of multiples (d and y) to choose from? I notice that the numbers in front of the letter refer to multiples of the KV rating, but the letters had me stumped.

Maybe not sure

IMO The 1515 1Y has a KV of 2200 . The 1.5 D has a KV of 2700 The 2 D KV is 2050 .
The 1515 1Y is a good race motor for a 33" well set up mono with a X447 , and would be fine sport motor with a X440
or X442 - X445.
In simple terms , The Y winds is series wound , in general has more torque . The D winds are parallel wound , use more amps , higher RPM less torque with the same number of winds as a Y wind.

A weekend ago I raced a Lizard with an SV27 motor and it was very fast in LSO . I think It was faster then My DF 29 with the same power. I got the starts but Rusty pushed me very hard every heat . Unless your racing I doubt you need NEU power .

Why dont you set the Lizard up for P restricted offshore ?? keep the KB on 4s2p and its done!

lest then you can race it in a class

Yeah Might get one of these KB45-08L 2300kv and be done with it

I would have thought that the sv27 motor would have been a bit small for it i run KB8Xl in it now

I have a 1515 1y in my df33 on 4s2p and its great. It does 54-55 mph with a x642 or for longer run times a x637/x640 and its still around 50 mph. Its seems like a great setup for this size mono.

[Fluid]

The Lizard is not a DF33 and the one I race against in P Mono is pretty flighty at higher speeds - no wonder it runs so well with that lower-powered LSO setup. And a racing setup is not a "blast around the pond" sport setup regardless of the prop used.

Running a high-powered Neu at high rpm/low load with a small prop is not efficient and can result in a hot motor/ESC. As Dick stated, a Neu motor is probably overkill for your intended use, a good 9XL or 10XL is probably a better sport motor choice for that hull.

Do whatever you want - it's your money. But you did ask for input.

I don't know how the lizard handles at 50+, I was just giving him a setup of a similar size mono. I have a 9xl in my other mono and it works well also with speeds in the upper 40s.
