It's not completely necessary, and usually some locktite on the grubscrew will suffice. If it ever starts to slip, use a dremel or file to make a flat spot for the grub screw.

If works fine, good, you don't have to yet. But as others said, you may need to later. Me personally, I start with the flat spot
People here hate Nitro, I love it. I start it, run it about 50 ft from me and it dies, I go after it. Perfect exercise |

My Neu came with a flat on the shaft but I usually make one anyways. Some say it isn't necessary but I'd rather just do it and KNOW I wont have a problem down the road.

I must be doing something wrong then because even with blue lock-tite on the screw and torqueing it down (and I'm not a weak guy), the pinion started to slip in about 10 minutes. This was on a steel spur/hardened pinion setup so that may have something to do with it.
I would just grind the flat spot. It won't hurt anything to do it, and will prevent you from having to unmount it again later if you decide you need it. |

If you're planning on racing, I would do it. You would hate to lose a race because of the pinion slipping or coming loose. I just put one on my new NEU last night. It had a flat spot already but wan't where I needed it.

I like it when the motors don't come with a flat spot so i can make on myself. That way i know it is not to big and is exactly where i need it. The more flat spots the weaker the shaft.

I agree. I like a nice quaint little flat spot. When the manufacturers do it, it seems they lop of 20% of the shaft.

With my 9L on a rustler I have the opposite problem, I can't get the pinion off, but unless I fry the motor I don't see a need to remove it, if anybody has any secrets I am all ears.....
