1412 motor kv chart

[FG101C]

Ok, so about a month ago I ordered a 1412/1.5/Y NEU from Castles site. I ordered this model because I wanted a 1350kv motor. According to the motor chart AT THE TIME I ORDERED the motor 1412/1.5/Y was 1350kv. So as I waited for the motor I sold my 5s packs and picked up two 6s packs for the lower kv.

Here's where I am about to pull my freakn hair out and not even try to sell any of my rc and just chunk it in a dumpster. I had a bad run with a couple motors and a couple wrong kv choices. I said NEU is said to be the best, they are the best motors I've ever run so I bought another. I just checked the chart on both Castle's site and NEU's site and NOW according to the chart the 1412/1.5/Y is 1850kv. So if it is now I'm screwed again, this puts me in the 41,000 rpm range and way faster than I want, I mean my god the money I have basically flushed down the toilet is ridiculous, I just want to enjoy driving my buggy.

So what gives, is the NEU 1412/1.5/Y 1850kv or 1350kv? I know I'm not seeing things, that chart originally said 1412/1.5/Y was 1350kv, I probably checked it five times before I ordered, I would bet $1000.00 that it originally said 1350kv. And if the 1412/1.5/Y really is 1850 kv then thanks for screwing me over.

I'm so pissed right now I don't even know what to say anymore. Yet another weekend of missed racing. Guess I have a bunch of rc CRAP for sale.

...Maybe they will let you exchange it for a 2Y?

I knew I was'nt losing it, I remember thinking to myself the 1100kv may be too low.

That's wierd...

The 1412 should be the same kv as the 1512, so the 1.5Y is 1850kv. 2Y is 1380kv.

That makes sense. The thing that makes me think it is a 1350kv motor is I did get a chance to run it for at least ten minutes. I bought it for my Hyper 9e, went with the low kv because that buggy is geared so tall.

I was running a Tekin 1550kv truggy motor with a 15 tooth pinion on 5s. That motor would get to 160 degrees and stay there, which is fine. I did'nt have the 6s packs yet and wanted to try it out on a 5s I still had. Well after ten good minutes (thats all I could get because the buggy broke....again) of track time this 1412 only temped at 97 degrees, and the battery showed 63% still in it when I put it back on charge.

An 1800kv Medusa shot to 170 degrees in no time on 5s, so if this 1412 is 1850kv, it would have been way hot and the battery would have been close to empty. So I don't know, thats why I'm confused.

The 1412 is in my 808 now, so all I can do is charge up a 6s, throw it on the track and see what happens cause I can't spend any more money on this.

Just gear it down if it is too fast... 1850kv on 6s is fine, and you may find that the higher motor rpm coupled with lower gearing is actually more efficient than lower rpm with taller gearing. Lower gearing equals less load. I can imagine it will have a snappy bottom end, but you can tame that with esc settings if necessary.

I found that the cc 2200 motor on 5s lipo (44k rpm or so) was very efficient in my lst. To be honest it may be almost as good as the 1521 1y on 6s (less than 39k rpms) and the lower torque levels made it easier to drive. Most motors have a sweet spot, never found that spot with medusa motors, so i gave up on them and went back to neu. No experience with tekin motors, but I still think the neu are the best available with the cc 2200 coming a close second!

I had a few medusa motors in a buggy and they all ran too warm for my liking. There is no comparison to neu, and the motors were not that much cheaper. All of the materials were a few steps down on the medusa motors, you got what you paid for.

I completely agree.I run a Neu 1512/2d (2550kv) on 4s which puts my rpm at just shy of 38000 rpm and love it. When geared down it has tons of snap and the ESC is seeing enough motor revs per mph so cogging is nonexistent at any speed. Yo0u may find the motor getting warm if you wind it out at top speed and keep it there though, so just play with gearing.

Or, since the motor is new and unused, see if they will swap it out for a lower kv. Explain the misunderstanding and see what they say.

Ok, thanks guy's, I will play with it before I decide my next move. Would have been nice to screenshot that original chart, but who would have thought. BrianG, the speed calc shows 1350 for the 2y, I guess it's 1380 now, and there's another one showing 1500 that Neu is showing 1475. Not much of a difference, just thought I'd let you know.

Thanks again.

Well I'm happy to report that whatever kv the motor is it is perfect. Probably the best setup I have ever ran. Motor temps were 125 degrees, battery and esc were warm at best. It has plenty of bottom and plenty of top and run time was right at 20 minutes with a 3600mah 6s pack.
