Let's upgrade to an entry-level Rc car Big Rock V3 4S

A cheap and beginner-friendly RC car
Upgraded Arrma Big Rock V3 from 3S to 4S.
Of course, 3S is enough, but I upgraded it to run more fun.
A more powerful driving is expected with the 4S change.
ESC, motor, shock and tire upgrades.
I tested it for a short time, speed and power are no joke.
I will upload an exciting driving video soon.
