Sorry, my mistake is from Poland and I slipped my tongue
Hey, I'm asking for help, I want to build a go-kart for off-road play and I need a construction project, maybe even a combustion project, I'm going to install a 3 kW 3k turbo engine from Mxus with a 6T winding and a Kelly controller for 60v 120A
First - welcome to the forum.
So now, a little more info is necessary to give good advise on building a frame that will be safe to play in.
Your skill level and tools. Are you a novice builder with minimal tools, or do you have some experience and
access to a welder, preferably a MIG or TIG welder, along with grinders, tube bender, etc.
"Off road" doesn't really explain much - could be an open, relatively dry and flat field to a path through a
woods with mud holes, tight turns and very rough terrain.
Give us a little more info to work with and we can help you easier and make a safer kart that won't crack
welds during every ride.
