Savage Flux XS Castle Electronics Question

What I am curious about is the specs of this gear, given a lot of people report the motor in particular runs quite hot. Branded as a 1410 4000kv motor, how does this compare to the Castle Short Course 3800kv motor? What temps are safe for this 4 pole motor given reports of 170-180f are common (I thought we left the hot temp on motor days with the 4 pole series)

What are the specs on this ESC? We wouldn't recommend a Sidewinder to someone doing a custom prodject with 100+ amp draw on start up. Yet my Eagletree shows the Flux XS is more Amp Hungry than the Flux HP! 110 Amps on start for the HP, 145 Amps on the Flux XS, all through a Sidewinder? That was on 2s, on 3s it'd be huge? Can the ESC safely take this?

Will we see a significant reduction in temps if we remove the HPI Branded 4 pole and install a Castle SCT 3800 motor (given that Castle has said the Alphastar 2350 motor in the Flux 2350 is essentially a HP Motor with weaker magnets, is this HPI one the same deal, weaker magnets, lower efficiency, higher temps?

Would appreciate the input, I am tentatively starting to trust Castle electrics again, the MMM in my SC8e has been behaving of late, and I am hoping the XS electrics will behave as well.

The motor is a slightly less expensive version of the 3800kV motor, with just a slightly less expensive stator and rotor. The main differences are the stator laminations (.35mm on the HPI, .2mm on the Castle) and N35UH magnets instead of N38UH magnets. Not a big difference like with the 1517B motor and the 1515.
