Quick question for the forum. I am thinking about racing my slash 4x4 over the winter and wanted to upgrade the motor and esc. I currently have MMM that I would like to run a Nue 1509 1.5d (4500 kv).

Does anyone have any experience running this motor is a slash 4x4. Any heat problems and what gearing are you running?

That motor should be fine in the 4x4 slash. I run a medusa 3650 4800 in my slash 4x4 on the mamba max geared 13/50 on 2s with no issues. the nue motor is a little more powerful should it should be even better.

Thanks for the reply slasn. I think I will give it a try. Anyone else have any experience with this motor and know how it compares to the 550's that are out now.

A 1509 will have more torque and run cooler than a 550. The 1509 is a four pole motor that is slightly shorter than a 1512 which is what is typically used in 1/8 buggies. 550s are two pole. I have run a 1509 in an 1/8 buggy and it would be great in a 4x4 sc.

The only thing is to make sure you secure the wires coming out of the motor so that there is ZERO play because over time some of the windings start to break from vibrations and it will cause heat and eventually the motor will fail. This is a known problem with Neu motors because they are not really designed for vibrations from car usage.

Thanks for the replies. I ordered the 1509 1.5d from rcmonster for $99.99 which seemed like a good deal. It is the smooth can and not the finned can version so I hope that will not make a big difference in heat. Worse case I will get a heat sink for the motor. Once again thanks for the feedback.
