Good Lord what a beast!
In light of the good performance of this field weakening, I just ordered a 48 tooth sprocket to multiply the torque more while the FW provides additional speed. Maybe there will be another video next week. If I can blow up this motor, there will be a new one the week after that. :LOL:

Lookin' Good! :thumbsup:

You got "skills" :2guns:

You should build an Electrathon kart
...to help hone those skills (efficiency, endurance etc.) :cheers2:

I'm building one
...& then, we can race them virtually :sifone:

I will have to work on my frame fabrication skills. I have only built one full go-kart frame so far. The rest is all modifications to frames.

This would be a great project for working on your frame fab skills. ;)

They are mainly just light weight
...but, high performance go karts (small electric race cars) :auto:

Maybe just try-n-design one in your head :thumbsup:
...or CAD
...or something
...& then, share them thoughts with us :cheers2:

Like, "if I were to build an Electrathon car what/how would I do it?" :unsure:
...or "what kind of "propulsion/package" do I think would be most competitive"
...& "last for a whole hour of racing?"

I think you (& many others) can do this :2guns:

Come on & join me!
...& if we can't race 'em together, then we'll just race 'em virtually :wai:

Fine tune them skills a bit
...& you'll "get" him :thumbsup:

Do you know how long that track was?

Have any idea how many laps you ran?

Would your battery pack last for an hour?

The timed portion was about 550ft. A circle of the lots is 1/3 mile.

I did a bunch of laps including snaking the whole lot a couple of times. I cut the footage way down to what seemed more interesting.

The pack lasts a long time. The previous video with my kart doing the 1g launch with Zach on it and this video plus driving 50+mph a couple miles each way was all the same charge. Zach loaded his gas kart in his truck and took it out while I drove mine there. I put about 20 hard miles on it that night and the pack was still above nominal voltage. I have never run it down; it takes too long.

My friend with the 212cc racing kart sold it and bought a racing kart with a 6-speed and Honda 450cc...

Here's what happened.
