Hi and welcome to the forum 🍻
Hyper 7 is a great buggy and built like a brick outhouse tough as old boots
parts are pretty cheap and usually readily available Nice find

With the Hyper VSe theres 2 versions 100A ESC 4s and the 150A 4-6s version i find my 100A version more than capable but i reckon the 6s version is nuts 🍻
