Neu 1527 vs lehner 2260 in a mono

[kfxguy]

There was a few of you guys that wanted to see the difference between a lehner and neu. I don't have matching kv motors so it's not a very fair comparison especially since the lehner is rated at a load (what kind of load and how much I don't know). The lehner is 1644kv and the neu is 1500kv.

Short story on how this came about. Sold a seaking 180 to a member. Something was cutting out on him so he sent it back to me to check. I thee it in the mono with a neu 1527 to test it. I couldn't not post these vids because the boat ran quite well. All runs were on 6s. M445 prop first then a m447

First run small prop 46.0mph

Here's an m447. 51.2mph

Here's my thoughts. The neu didn't break a sweat. I didn't log it but I'm sure it didn't pull near the Amps. It feels like it's not working as hard, basically comparing the two motors would be like the neu is a big block Chevy and the lehner is a high revving turbo charged small block.

I think the neu could use more prop. I'm gonna try an x450 on it soon. This is a nice sport setup or a roundy round setup. Note: I had the smaller sized turn find on it, if I had appropriate sized one, it would have turned even better.

Here is the beginning run with the m447 prop.

Being a Fan of Neu, it is with a heavy heart I must admit there is no comparison. After seeing The pure precision and smoothness of a Lehner on a bench test I am not surprised your data makes the case. While many are very stubborn when it comes to the cold hard facts, it is what it is. Reminds me of my stubborn days when I thouht max amps batteries were the best. After many runs with truggys, boats etc... I not only concluded they were slower but quite inferior to many "A" and "B" batts. I agree with you on revolectrix. Best i have ever had and the price is a bonus.

Here's a 6s lehner video.

Well B, it's not a fair comparison really. The kv is higher on the lehner, not by much according to its rating but they also rate the kv under a load. It would likely be closer to 1800kv unloaded if I had to guess. Now, the build quality is way better on the lehner. The wires that come out of a neu, very very poor design. I couldn't tell you how many I've fixed and seen fail because of the wires getting cut on the can. As a matter of fact this brand new 1527, one wire is already cut. Bad design.

I asked steve Neu about it and the following is his reply
"The motors are very different Kvs—in the motor world 99.9% of the manufactures give you the “no load” RPM divided by the voltage as the Kv—for some unknown reason Lenher uses a RPM number derived from what they consider to be the normal peak operating point—which results in a actual RPM that is about 80% of the no load RPM. This makes it difficult to compare apples to apples. To make a fair comparison you would need to pick a higher Kv motor of ours—something in the 1900-2000 range would give similar results since that is what the Lenher is if measured using the same methods..

Yeah, that's apples a cinder blocks.

Each motor is top shelf in my opinion. Just rated totally different.

Exactly.


Like I said in my first post, it's not a fair comparison. I posted this because when I was building the boat I had those two motors for it. Several people wanted to see the difference in performance between the two even tho they aren't the same kv or even comparable motors. The neu faired very well for its purpose I ordered it for....sport running.

[Bduncan]

both good motors. But i think the Neu is an S Class Mercedes and the Lehner is a Maybach. Bith fine automobiles but one is a bit smoother and has endless options. but you pay for it.

Try that 450 you mentioned. I run a few less KV on a Neu and can turn a 452. Works pretty well.

Yes sir I will. I have the prop already but I haven't worked it just yet. I need to put the sf300 Esc in it first too.

Have you played with the motor calculator? http://www.lehner-motoren.com/calc/rechner.php?la=en
Input your voltage an arbitrary number for amps and rpm then click on calculate. Once it picks a motor, change to the one you want to see, click on show diagram. Under the graph click on "data table for" and it will give a table of info.

I just check the price of those motors
