Very Hot Wires on the 1717? or is that normal

[Semi Pro]

so i got the muggy up and running this weekend and its a monster, I'm only getting about 20min of run time on my 5200mah 30c and the fan is running on the monster non stop so i have some questions

160 seams very hot for motor wires isn't?

the motor and lipo was around 110 if forgot to check the MMM but it didnt thermal so im guessing it was fine on temp. i stopped with 25% remaining in the pack because performance was dropping off and i though i was getting close to LVC.

when i pulled the pack it was alittle soft and i had though it may have puffed but after cooling and recharging it was firm again.

so is 5200mah 30c not enuff?

alittle more info if it helps

the muggy weighs 12.8lbs
it is geared for 50mph (that may be the source of my problems right there)
i am useing an external BEC
nothing is binding, i just went overeverything when i got the muggy from linc and then i went over it all again after i ran it

MMM settings
high start power,timeing is at low,
