I looked at Tekin's site on the Pro2 and Pro 4 and they do not advise using the Pro2 for the ET410 but for 4wd buggy class, the Pro4 4600 is for the ET410 class. I put the Pro2 5100 in my B64D and it does great in there. The ET410 is too much for the Pro2. The Pro4 4600 has no problem with the ET410 as suggested by Tekin. At first I was going to return the Pro2 5100, but decided to try it in the buggy, and glad I did. With the RSX you can run dual mode by disabling the sensor in mode one. These 4 pole motors run so cool, and are plenty quick. I am experimenting with gearing and temps to get as much speed as needed. The ET410 takes a lot of power to move it as it is heavier than a buggy, and we already know about the servo issues as those big tires can really beat it up. I wanted to add that the Pro2 5100 takes the smaller 3mm shaft pinion, and the Pro4 takes a 5 mm shaft. I also had to modify the motor mount bracket to allow access to the pinion set screw.
