Neu/Castles motors, FYI

[Rumdog]

my 1518 has max rpm 60,000 printed on the endbell.

Where are you guys getting your 1717 data from? Its not here on OSE. There is no 1717 listed under NEU's being sold on OSE. Its not at Castle. They only list up to a 1708? Its not at Neumotors they dont show it either? So where are these comments about KV and rotor dimensions coming from. You guys have a source?

its on ose..it comes up on the home page under the featured products listings...i believe it shifts positions when you leave and come back to the page

[RIPFENCE]

if you go under the motors and mounts section it is listed there under the castle motors at the very bottom too

I am getting the info from the Castle site.

If you dig deeper with some simple calculation, you'll find the power is tremendously propotional to the size(volume/mass). original Neu 1515 is rated at 1250W, 1717 is 1.45 times larger than 1515, so it's good for 1250* 1.45≈ 1800W, a bit higher than the 1521, maybe somewhere between 1521~1524.

But please note that the 1717 has a larger diameter rotor, so it's max RPM is limited to 45K if I remember correctly. 15 series are rated at 60K, some nuts even ran it up to 90K RPM and survived.

So here comes my thought, for same power and if motor length is not a problem go to the 1521/1524, you'll have both worlds, the power and rotor strength.


PS: Always wonder why Castle never rate their great motors in WATTS. forcing us calculate those basic numbers based on similar Neus.

Thanks Guy's. For the life if me I couldnt find it anywhere. I still dont see it on the motors OSE page but the link works great!

john its not a Neu motor. Its a Castle Motor, so its listed here
http://www.offshoreelectrics.com/pro...eations+Motors

Also give the search a shot. I use it all the time.

As for 4s with this motor. Its very conservative, I know. But for a untested motor in a boat, I wouldn't be honest in saying to use it with 6s.
It will "probably" be just fine with 6s. I just dont want to have a new guy read something and go put it in a giant boat with 6s and a x460/3 blade.

I'm putting the 1717 in a new 6S rigger. It's a little more kV than I wanted, but we'll see how it works.

I've gotten to play all but the 1717 at this point. So for what it's worth, here's my take on the Castle/Neu motors for us FE guys.

1512-1800 it's a great RTR replacement motor, no more rpm but loads more torque.

1512-2750 hot 4s motor for small hydros (I've run it in my old DH shovel, it's a rocket but not a sport combo). Also a good option if you want to run a spec rigger in open P hydro.

1515-2200 general all purpose 4S hydro motor. Reliable and fast without beating batteries to death. Also good in a smaller (DF-29 etc) P mono.

1518-1800 deadly P mono motor in a 32" DF storm with the right prop. Also good in larger P sport boats.

1520-1600 Should make a great P offshore motor. Also a hot 6S hydro motor.

1717-1580 I'm hoping it's a killer 6S rigger motor. It might be an amp hog, but we'll see. Reminds me a bit of the old 18 series Aveox motors.

Hope that helps.

Brian how do you think this motor might work in a 34" Cat hull on 6s?

Probably pretty good. It'll be the usual, start with a small prop and work your way up.

Ran the Rico again today. Setup was Castle/Neu 1518 1800kv, hydra 240lv, Turnigy 5s2p 10,000mah total, and a x447. Shifted the cg bac to 27percent. Insane speed!! This motor is AWESOME!! No heat to speak of from anything. My water is colder than freezing right now though which i'm sure is helping a bit. Just got a Garmin etrex tod, gonna gps her this weekend. I'm guessing it's quite close to 60mph!

[Rumdog]

Here she is, ready to rock!

Ryan, just a thought, I think you may need more then 20c cells... just food for thought.
Looking good.
