Nice work. I LOVE that battery mounting idea!

no, it does not appear bigger, it is bigger. That´s the mystic of my friend Jens Seidel.
1,85m MHZ Mystic. using 3060 LMT motors und jeti spin 200 esc and 10s5p at the beginning.

to be honest, i wouldn´t use the 1527. They have so much torque, you will get some problems with the flex cables. One of my friends tried these motors in the mystic and had a lot of broken flex cables.
the 1521 are realy goog for that boot. 8s lipos would be too much weight.
take the 1521 an 6s if you take the 1,5d with 1900 u/volt or take the 1521 1,0d and use 4s and for the realy realy fast setup 5s lipos.

here are some pictures

First off, thank you for all of the pictures! You have a beautiful boat, very well done.

Which motor will help me achieve higher speeds in the long run? It seems like the 1,5d on 6s would be faster, am I right?

All of your suggestions have been really helpful, and I am currently thinking of doing the following setup...

2x Neu 1521 1,5d
2x Hydra 240 HV
2x 6s 5000mah 45-90c LiPos

Another thing - I would go with the 240 HV ESC if it's necessary, but if I can use the 180 HV instead then I'll do it. Of course, if I'll get better performance with the 240 HV I'll go for it.

Thanks for all the help!

thx

I was searching quite a long time. I found nothing that would fit....for that reason i had to make my own mounting system.
I can adjust the lipos 3 cm in both directions and fix it with one screw only.

The 1521 1,5d on 6s will give you a revolution speed of nearly 41000 per minute.
If you take the 1521 1,0d on 4s it will be 41000 per minute too.
On 5s it will be nearly 52000 per minute.

The difference between the 1521 1,5d on 6s and 1521 1,0d on 4s is nearly zero.
There is just the difference in the weigth. Both motors will fit perfectly in the mhz mystic.

But keep in mind: If you go down with the number of lipos you use, you will go up with electric current. While I was testing different props on my mystic I installed a logger: Peaks up to 250 A and continuous current was sometimes up to 120 A.
My advice: If you have the possibility: take the castle 240.

Oh alright I see. So the boat would be faster on the 1521 1,0d on 5s? Since it'd be spinning 52000 rpm? Would that setup be hot?

I also forgot to mention I would like to have run times of at least 5 minutes. I don't want to just go fast for 2 minutes and have to cool the motors/escs.

I'll definitely take the Hydra 240HV now that you mentioned that.

You've been really helpful and I think I'm going to go with your exact setup. It seems to be really good for me.

52000 RPM ?? 35000 to 40000 RPM is a maximum

[domp444]

That's what I was thinking, Alfa.

[dropps]

52000 RPM ?? 35000 to 40000 RPM is a maximum

why????
where is the problem going 52000 rpm???

[domp444]

Haven't posted about this in a while.

I spoke with a friend, and he recommended the 1521 1y instead of the 1d.

So my new setup will be...

2x 1521 1y
2x Hydra 240HV
2x 6s 5000mah 45-90c LiPos

Anyone else have any comments about the setup?

I placed my order with MHZ yesterday, and I hope to hear back from Shirley soon.

hey
with the 1521 1y you will reach something aout 34000 rpm idle speed ( i hope you understand what I try to say....)
This means that you will have something about 30-31000rpm load speed.
Well, that´s fine for going 100-120 km/h, depending on the props.
I always prefer more rpm.
I would take the 1521 1,5d on 6S
Props: x447
Speed 137 km/h (85 mp/h)
Current 120A

That´s what my eagle tree told me.....

Very good information and nice battery mounting idea - very nice.

A friend of mine has same boat, 130 kph = 80 mph with

1521 1.5d (1900kv)
6s
turnigy 180
445 props

same as dropps suggestion

I heard that the d series of motors make ESCs go
Haha, that's why I was going to use the y motor. I would hate to blow a 450 dollar ESC because of a motor.
I understand what your saying about the RPMs. The d motor would definitely increase my speed.

You mentioned before that your current sometimes bursted to 250a, right? I was thinking of doing the Hydra 180 HV, but I see that the 240 HV is necessary. Thanks for the help

Everyone's recommending these d motors, haha. He's getting away with a Turnigy 180?
