Neu's come with a flat shaft right??

[mk351e]

I sure hope so! One thing I DO NOT feel comfortable doing is grinding the shaft flat on my $265 motor? I got a 1515 1Y coming, though I may cancel and get the tekno motor if they can come out soon enough.

Smooth shaft on the Neu.

If you grind a flat spot, keep debris from getting into the motor. One good way is to use a good strong ziplock bag, etc.... put the motor in it and poke the shaft out though the bag. Then maybe even tape around the shaft to make sure it's sealed good. Grind it with a cutting wheel or sanding drum and take your time.

I think it depends on stock - I think some of the new ones are coming with it...

the new ones come with a flat half way down the shaft, as long as you place the pinion on the shaft with the setscrew side closest to the motor you will be fine

My NEU motor that I got last week had a flat spot on the shaft (1512) but it didn't go all the way along

lengthwise the flat is probubly 1/3 of the shaft

Yeah pretty much, I only looked at it once and put it back in the box as I can't really use it until the ESC and motor mount arrive

The 1509 I just got didn't have any flat spot... maybe it's from older stock or they are only doing it on the 1512 and 1515?

The flat spot on the new neu's didn't match up for me. i had to make my own on the other side. I like using a thin flat file (jewelers) better than the dremel. More control I think.
