Default ESC gets HOT

im working on my uncles kyosho rc surfer thats been sitting around for 8 years.
I got all new electronics, cheap 320amp esc from ebay, TX/RX from dollar hobbyz and a brushed hpi motor dont know what turn.
I just test run it and after 5 mins the esc was very hot.... not sure why?

with that setup it needs water cooling or ventilation and I'm guessing its getting neither.

you could add a fan over it to draw off some of the heat

The Kyosho props have a lot of pitch to them which can also lead to an overheating problem. Some of their shafts are metric but a tiny piece of brass tubing over it can take care of any slop between the shaft and prop. That piece that the prop fits on is called a drive dog.
