Absolutely blown away by this powertrain.
I converted my BirelArt AM-29 from LO206 gas to the GoKartGod Nighthawk system, and it has completely changed what this chassis can do. On our small track here in Houston I'm seeing around 63 mph, right in the same window as the fastest karts running that circuit. The difference is how it gets there. The torque is instant and relentless, and there's no shifting, no clutch engagement point to manage, no waiting for revs. You just point it and go.
What really surprised me is how playful it is in the corners. The power delivery is so controllable that you can steer with the throttle in a way that's hard to describe until you've felt it. It rotates beautifully and puts the power down exactly when you ask for it.
I just ordered a second battery pack so I can cut down the turnaround between sessions. That's honestly the only limiting factor right now, and it's an easy fix.
Bottom line: this thing is an absolute blast. I can't wait for more people to get theirs so we can put together an EV division here in Houston. If you're on the fence about converting, do it.
