Tekno RC Neu or Orig Neu
 

If you have a choice between a tekno RC 1515 1Y/F and original 1515 I Y/S, which one would you buy?

Motor will be installed on a Gmaxx.

Well the Tekno one has bigger bearings and has sealed can, so Tekno

IIRC the differences are that the Tekno Neu has a sealed (can no dust but may run hotter), larger bearing, flat spot on shaft, and machined wound. I also think they made the mounting screw holes deeper.

Is the rest really the same? Quality of wind, wire, magnets?

mine runs rather warm on 4s and 5s, tekno neu 1515 1y, after 15 min it was 160* on a 70* day


i may change gearing , but think it is ok for now

Huh? But which one would you prefer? The reason I'm asking is I got an email from a vendor stating that have the smooth can orig Neu. However, I also bought a tekno rc neu and I'm hoping for delivry this week.

i have never ran a original, and the tekno is supposed to be more car oriented, but seem to have a little higher temp and weaker magnets to decrease cogging

The TEKNO RC Neu is finned so I don't understand how it have higher temps (given the same gearing and everything) when the fins are supposed to dissipate the heat quicker than the smooth can. I remember a post by Tekno RC stating that everything (magnet,poles) are the same between the 2 with the exception of what's noted previously by mkrusedc.

I have to question your comment about machine wound - please post where you heard this information.

Straight on the Tekno RC website it posted that the motor is hand made:

Tekno RC strikes again!

This time we've teamed up with the world's best motor manufacturer to bring you the finest 1/8th scale electric brushless motors available.

The Tekno RC Edition Neu Motors feature:

* Larger 5x13x4mm bearings front and back
* Sealed motor can
* Rear end bell is safely secured by Neu's latest design, a must for any car application
* Flat spot along length of shaft (no more grinding)
* Industry standard easy to find 4mm bullet plugs installed
* Cool blue anodizing and signature finned case lets your competition know you aren't messing around :)
* A selection of winds will be available to suit 3, 4, 5, and 6s 1/8th scale buggy and truggy applications
* These are genuine hand-built Neu motors, not mass produced

these are just my observations..............:whistle:

so dont shoot the messenger:rules:



the closed ends , and weaker magnets - supposed to reduce cogging(there is a thread around here somewhere about how easy the tekno neus turn compared to a original neu) must make them run hotter, and maybe not as effiecent(sp)

either way i am very satisfied with mine, i just hope with a little gearing change i can get mine around 120* on a 70* day so it will be about 50* above air temps

I thought hot for a BL motor was 200 degrees???? Anyways with as good of quality as the Neu's are I would not worry too much about 170 degree temps. JMO

I don't see the closed ends as a detriment to the design. We probably mostly all run the rear RCM cover and do something to cover the holes in the front to prevent dust from getting in anyway.

I've got a 1509 and 1512 and the Tekno 1515 and I don't notice the Tekno motor spinning more easily by hand at all. Wish I had a 1515 to compare it to.

I can tell the Tekno 1515 has definitely got some more kick than the 1512, temps are lower, Amp draw is about the same (which makes sense - 2050kv for 1512 and 1700 kv for 1515). I am a happy customer.

My only complaint is the pre-attached bullets, took me an extra 2 minutes to unsolder them to put on the 6.5mm ones. :tongue:

My 1.5d Tekno did not come with them preattached. Glad too unless it would of been the 6mm ones.

There is also a topic on the Tekno/Neu Motor which may help out http://www.rc-monster.com/forum/showthread.php?t=12456

here is the thread that i was thinking of

I finally receive my Tekno RC neu 1515 1Y/F today. Wohooo. I can turn the shaft easily by hand too.
