You for sure need 6s minimum, 4s will get you like 4mph lol… use 2 of these in series
Also try using a Vesc, it will cost a bit more but is so worth it
Then you’re looking at 30mph…that ESC will probably go first and you’re gonna need a lot of connector harnesses but it should be good for a first build
If your willing to wait, hobbyking have sales often on lipos. I got 8: 3s 5200mah lipos for ÂŁ60
It’s is a vesc but for copy right reasons it’s called a fsesc.
The torque is probably better quality but people have found the flipsky 4.12 to be pretty solid.
homie its not hard please do some reading. especially with vesc programming. You can make a big investment go down the tube if you program it incorrectly
