Neu vs tp.......would you agree with this?

[kfxguy]

I'm trying to map things out for budget builds when one simply cannot afford a neu motor a tp motor could be substituted and be very close to the same power. I've made up a simple chart and wanted to see what you guys thought. I've you've compared them please let me know your results.

4040 = 1515
4050 = 1518
4060 = 1521
4070 = 1527
Nothing yet = 1530 lol

I've got a build I'm working on with a 27" cat. Wanted something equal to a 1515 (had a 1515 in the same hull before and performed well) and I was going to put a 4050 in it but a 4040 might be closer in power to a 1515? Wanted the choice of different kv, because if I was to go 1515 the castle version is much cheaper and easier to come by. The tp 4040 might be a good alternative, no?

Leopard 4072/2200kv. Cheap as your going to get.

Not what I asked and no thanks. I'm not a fan of leopard. i like tp much better.

First you ask about Neu vs TP
Then you mention 1515 the castle version.

Are you comparing Castle or NEU vs TP

Tp vs neu. If I needed a 1515 2200kv I'd almost never buy a neu when you can get a castle (same motor basically). Never mentioned leopard in my original post so I'm not sure where that came from. What I'm asking is quite simple, in the order compared, are those motors about equal?


To clarify, I wasn't comparing neu to castle. I made a very clear list of what I'm comparing. I mentioned a castle 1515 simply because I had that motor in the same hull previously and it performed well (and we know a 1515 castle = a 1515 neu) So like I said, do the neu vs tp motors compare.


(Scratching my head wondering how you got I'm trying to compare neu to castle in my post)

[TRUCKPULL]

we know a 1515 castle = a 1515 neu

A Castle is NOT the same as a NEU .
A Castle was designed by NEU for Castle

Castle has
Less Max Volts
Less Max Watts
Less efficiency
Higher internal resistance
More weight
This is just to start

I knew this was coming. Read my post. I said same motor BASICALLY. I said basically because that leaves the comment to be pretty loose and I could tell by your post that this type of agitation was going to ensue. I don't care that a neu and a castle are not the exact same motors. They are close enough that I've run both in the same boat and got the same speeds within a couple mph. Close enough for me. Anyway, if your not going to contribute to this thread, please carry on. I have a legitimate question and I don't care for the childish antagonism.

How so? I specifically asked if the tp motors and neu motors listed were comparable. You felt compelled to tell me to get a leopard. What? Really? If I were I interested in a leopard I would have included leopard. So I didn't. Is that clear enough for you to understand? :)

Lets go back to the beginning.
You want to compare a 4040 TP with a 1515 Neu 2200Kv

Where can we find the spec's on the TP motors to look at??

Whew. Thank you. This was getting ridiculous.

The 4040 weighs 396g
Watts 1650
Max watts 4200
Diameter 39.5mm
Length (this is contradictive, listed as 71mm on one page and 66mm on another, different kv but if you look at the custom build chart the length is 71mm)

http://www.tppowerusa.com/motors/in-stock/tp-4040-2080-kv

Neu weighs 340g
Watts 1250
Max watts 2500
40mm x 68.58mm

I had to convert the neu measurements to metric

[kfxguy]

And I want to add, I know for sure a 1521 and 4060 are pretty much identical in power. I tested them both in the same boat. Same batteries. Same prop. Same lake. One went 77mph and the other one went 78mph. Both 1860kv

Looking at the spec's on the TP's
They say that they are 4 pole motors
TP - 4040 2Y (4P) =3770Kv
Neu - 1515 2Y (?P) = 1100Kv

I just found this information.
All 15 series motors have 12 slot stators and 4 pole rotors

Where the TP say's 4P is that Stator or rotor????
I would presume Rotor
The question then is, what is the Stator count on the TP seeing the Kv difference?

Well honestly I'm not concerned with kv difference.(I posted those links just for reference for general specs and how they contradicted each other) My concern is if you had a 4040 2200kv vs a 1515 2200kv, would they be comparable in power. I'm thinking yea because of the 4060 vs 1521 test I did. The tp was actually a tad faster but did run a little warmer. I think looking at specs is going to be misleading because I think tp over rates their motors a little and neu under rates theirs. Looking at the weight you'd think there is more copper in the tp but I think I'd put money on the weight not being quite as much as listed. I have several neu 1521, 1527 and 1530's here and some 4070's, 4060's and 4050's and the tp's feel lighter. (No 4040 here tho) I guess there's a weight comparison in order to see.


I know that tp is 4 pole rotors but I don't know on the stator. Not sure that even matters.
