Hi mate, I did put those difs in a blackzon but had to grind the casings a bit. My alliexpress car came with the metal drive train

You probably could have used the regular ESC it could take 3s. Or all my cheapos does but the sper never lasts to long.

i have 2 if thise hbx and they are perfect and bullet proof. The only thing missing and i dont know how but no one ever thought about bulding one is an adjustable motor mount to allow bigger motor pinions and increase topspeed....

Me he pedido uno igual de Ali express para usarlo con mi hijo estoy en Perú es difícil conseguir los repuestos si no es por Ali express y traerlo es algo costoso pero el está entusiasmado y bueno lo probaré algún día lo mejórate con sus piezas de metal y motor brushless se ve muy divertido 👍👏

They are mad with 3s😂
