Hey,
I picked up a used Rustler VXL with a Losi Xcelorin LOS9515 ESC. It has the same issue that the original poster described.
I don't have the USB cable and software to reconfigure the ESC. Does anyone know if there was a newer version of the firmware released or is it still at .34?
Does anyone know a fix? Should I get the Castle Creations Mamba Max like the original poster?
Thanks for any info.
