Default Brushed to Brushless conversion help!

Hey, is I bought a Volcano Epx Brushed rc car, and I'm converting it to a brushless setup. I've got the motor and the esc is coming in, but what else do I need to convert? Please list all things. Things the might wear down or might break or just need to be changed. please help!

You need a LiPO and a new charger as the stock one cannot charge a LiPO pack. Pretty sure those Volcano EPXs have metal transmission gears stock.

No, stock should be okay for now. You won't really be able to tell until you actually get out there and run it.

I don't think you need one. Like I said, you're just gonna need to try it first.

converted my sons Latrax SST to brushless, since the brushed motor kept eating dirt and couldn't handle a Lipo battery. stock gearing would be fine unless the test drive says otherwise.

Get an infra-red "no touch" thermometer for monitoring motor temps. It's the only real way to know if you have it geared right.
On a warm day, the motor should never get above 160-170F. Should run all day at around 140F or less. Motor temps above 180F run the risk of de-mag-ing the magnets or melting winding insulation.
