1406 4 pole 4600kv

I agree with Patrick !
torque control is really great !

Well, because Dena was kind enough to do an exchange, I sent the 5700 back. It means I have to wait, but it should be worth it in the end.

I sure hope someone has a suggestion for me. I just installed a new Castle Creations 4600kv 4-pole motor in my 2wd Slash. At the same time I changed the diff fluid to 50,000wt and change the gearing to 18/86.

On my test run in the street it pulls very aggressively to the right (to be honest now that I'm back in the house I can't remember if it was left or right) when on full power. I mean it will sometimes just spin out because I can't counter steer it enough. Especially from a stand still. Clearly one of the wheels is getting more drive than the other, but why?

I've checked the wheels and drive axles and nothing seems to be binding at all. There are no weird noises either.

What could be the cause?

I hate tearing into the diff on this truck. You have to remove so much to get to it. Otherwise I'd investigate, but hoping to get some clear suggestions from people who may have experienced this before I open anything up.

I've experienced this where a hub pin is broken and you can't see it until you take the hubs off.
Come to think of it make sure your center drive shaft is working with both front and rear hubs attached properly to the center diff/slipper clutch and the front diff too.
Once a set screw was able to back out and not until I took it apart I didn't see it.

This is a 2wd Slash.

Power seems to getting to both wheels, but more to one of them. If I hold the truck rear bumper, it lays an even amount of rubber on the ground. To me this means neither side is really slipping or losing drive.
