Number cells/Motor Kv/Prop Size/Hull Size

1Y = 1 turn of windings terminated with Wye wiring pattern
1.5D = 1.5 Turns terminated with a Delta wiring pattern

8L vs 12L is only a difference of number of turns for the motor. Both motors will handle the same amount of output watts. Thus both are equally as powerful. Select the best winding based on the amount of voltage you plan to use.

The 1527 is more powerful than the 1521 as it is a larger motor can. It will dissipate more waste energy and output more mechanical energy when setup correctly.

Thanks Ryan thats really appreciated.

I think i will stick with a Feigao, for my hull setup do you think i should still go for the 12l or move up to a 8l?

Thanks

I would use a 580 9L 1426kv. Excellent for a 6s mono.

Are the ETTI ESC better then the Seaking ESC's.?

I was going to get the Seaking 180a ESC but iam now looking at the ETTI Race 150 Brushless ESC.

Will this handle the Feigao 580 9l brushless motor and 2x 22.2v 6s lipos in parallel or am i better of with getting the Seaking???

Thanks

Well i have gone back to the Neu motors

I think i will go for a 1527 1Y or a 1527 1.5D, what do you think for my setup?

[agressive1]

The setup iam wanting to run is apparently to heavy for the motor choices above, a 1527 is to large and so maybe is a 1521.

Apparently i will kill my seaking 180a esc and my batterys are not good enough for the job.

I have been told to get a 1415 or something along these lines?

[ryan_t888]

What hull is this for, I can't remember>

Ryan

I will tell you my set up and what i have got.

Hull: SpeedMaster 45, 37.5" Long
Hardware: Speedmaster Hardware
Motor Mount: Peter Zichas, 5" wide for a 1521 to 1527 sized motor.
Speedy: Seaking v2 180A
Prop: Octura X646 "Can be changed"
Lipos: FlightMax 5000Mah 22.2v at 6s x2 in Parallel
Connections and Wires: 10 Gauge Wire, with 5.5mm and some 6.0mm Plugs

Now i have been told that my hull is to heavy to run a 1521 or a 1527 as they will push out to much amperage and will not be sufficient leading them to kill my Speed controller etc.

The motors that i will be buying are from Fast Electrics in Australia, they are specially made for Andrew who is the owner of Fast Electrics and are known as a full racing competition motor which is built by Neu, Andrew believes that i can not run the motor in my boat due to my setup as my hull is to heavy and my lipo packs can not keep up with the motor neither can the Speed controller.

Andrew is trying to sell me a 1415 or something but my engine mount will not fit it, i believe that motor is to small my self.

He tells me if i get a Standard 1521 or 1527 it will be more sufficient for my hull setup. But i can not find anyone who sells them.

Please what are your thoughts?

[ryan_t888]

I would definitely not go any smaller than a 1521 for power. A 1527 would be ideal.

I would run 6s minimum and 8s for sport use.

Ryan thats what im not understanding, why would he want to sell me a smaller motor if i got a heavy hull.

Do you still think the 1527 1Y is idea or the 1.5D?

Although his Neu motors are slightly different to the standard ones that OSE sell, im guessing it wouldnt make much of a difference will it?

[ryan_t888]

How are they different? Are they the older style. Kv is slightly different if so.

Ryan

[agressive1]

Apparently they run harder then the standard Neu motors, he cant tell me specs of them as they are specially made for him and for buyers to buy of him.

[ryan_t888]

Order from OSE?

Thats preety slow for my liking hopefully with a 1527 1Y it will go harder.

I would love to order from OSE but they dont have any in stock, i would like one as soon as possible.

Iam going down to the boat club on sunday as they are having the fastest straight line runs and as far as i know theres a few Brushless people down tehre so will have a chat to them and see if they have any motors to sell me and or if they have a good supplier.

If not OSE its going to have to be.
