What motor mount?

[Gordo]

Ok I have the pps motor mount and stupid me bought the castle 7121 2400kv which has a 8mm shaft. Did some dremel work but I don't want to take to much meat off of it to make it work. I flipped gear and the grub screw are right on the end of the shaft. Right know I have it meshed about 3/4. Whats my options?

Do you have a spool or diff?

I’d end mill the grub screw slot deep enough to have full teeth contact. You’ve gone this far, it’s not a basher I presume.

Perfect. Strictly speaking, you could run your car like that and not have any problems. But I can fully understand the desire to want the gears to mesh as much as possible.

So...what you need to do is adjust the spacers of your spool so that the gear lands where your pinion is. You can use 8mm washers to create alternate spacings.

There's the allen pin that goes through the shaft that the spur, but I did a little dremel work. I think I'm good now.
