I've replaced almost all the internal parts.
Extreme-Fire SW-AB-Long MOSFET custom made without AB (yeah, weird I know ). I've replaced the fuse with one I made, and I've added a tracer unit control circuit of my own design, which enables any battery to be used with the internal tracer unit.
New wiring, using this 16 AWG stuff. It's nice and thin, but the insulation is tough and heat resistant.
XT-60 connectors - Loving them at the moment.
SHS High Speed motor - Excellent performance.
