i know you're experienced in rc, but the components are under immense stress for only a few seconds, and even when something breaks, it's not like you can't replace it.
and for reference 3X,
the lightspeed x2 pro specifications:
12T of silver wire on spiral arm with Copper FAT comm, 10-15 degrees advance timing, Atomic EGR bb case, neo mags, 18G motor wires, carbon brushes, pre-lubed with Tribo comm lube.
