Castle 1717 motor with free water jacket

I'm going to move this thread as it has grown into a disscussion. instead of a sale

Anybody track down #of poles & Max Watt rating for the 1717s?

I posted some ?s on RCForums MFRs`Castle thread' but no answers yet.

I've not found any info on the 1717 but the 1520 is a 4 pole motor, constant watt rating of 1750 and burst of 3500watts
so maybe 10-15% more for the 1717?

I am looking forward to finding out more about these as well. The 1717 isnt a Neu design like the other motors, its castle's creation I dont know if that even means much but I guess I will find out as I have one to test. It just seems odd to me to have 2 motors of roughly the same kv, and the same Amp rating. According to how theyre rated, the 1717 and the 1520 should perform quite similar...I dont know that they will and cant say I put a lot of stock into their ratings.

So... I got ANOTHER air motor... in a car motor box... Even after calling to confirm..

Pretty messed up stuff going on there. Anyhow... I was thinking... it might be better for a boat? It's open, so will allow more air flow for better cooling...

I was thinking of running it without a jacket and just using it moderately? Any thoughts on that?

[Rumdog]

Throw a fan in front of it. It may cool better than the enclosed version with a jacket.

[keithbradley]

It has a different shaft, different mounting holes, the flat spots ground in the fins, and the holes in the endbells. It also may be a 2 pole motor...Im not sure by any means but it definitely doesnt feel the same as the other Neu/castle motors when you turn the shaft.

Not that any of that is a deal-breaker...Just making sure you noticed all of this stuff.

Well, I have one of each, so it's worth a shot! Worst case, I goop up a cooling can on it!

Anyone have a link to good cooling fans? Should be able to buy a handful of them cheap in the right place.

Ben, I talked with Thomas porfet about that same issue. My 1520 order came in as a 1512 in a 1520 box. I told him about it and he said they hired a temp to box all the motors. He called the warehouse and found the temp had mixed up some motor and box combos. He said they will be checking all of them in the warehouse. Can't imagine that temp will have the option to stay on.lol

That would be my only concern.. if it's a less powerful motor. Although I would think that the air version would have more torque for a propeller so it would have more poles?

It does spin easier than most though. I did notice the bolt pattern, but it still fits my mount.

IDK... It's headed for an Osprey... so guess it doesn't matter too much.

Did you happen to see the thread about the neu 1527 I had? It was much easier to spin by hand than my 1521 or 1515.

Yeah, something about the winds IIRC..

Ya. Point being, a 1527 is a beast. The difficulty of turning the shaft must not coincide with motor power, according to the replies I was getting.... Btw,I got that servo. Thanks again bud!

[Rumdog]

Yeah, the turning by hand means nothing. My 1527 1.5d and 2215 1y turned much more easily than a 1515 1y. I mean, a proboat BJ motor is harder to turn by hand than any of em.

Yeah, but I like not being able to spin the shaft, it adds to the machismo!

I put a new connector in the bag for ya. Hope you found it. Like my inventive packaging? Keeps costs down.
