flm rusty heat issues w/ pics

[t-maxxracer32]

hey guys just recently i got this up and running and its having a little heat issues. specs are................... 5700
mm esc no ubec
2s2p a123 pack
86/20 gearing




i bought the illusions body for it but now im just waiting for all my airbrush equipment

after maybe 5-10 minutes the motor and esc hit around 140 and the batteries are warm.

should i change my gearing? or put a ubec on the esc? would 2s4p of these a123s make a difference?

thanks for any help!
