Your kart fades near the end of a session. Now you can see exactly why
Your kart is rarely as fast on lap 12 as it was on lap 3. Race Ninja's new lap-by-lap performance graph shows whether it's the engine, the tyres or the track losing grip, so you can stop guessing and start tuning.

If you've been using Telemetry Overlay, or you're weighing it up, here's an honest take on when it's the right tool and when it isn't. Telemetry Overlay is genuinely good at what it does. It reads GPS and sensor data off a GoPro, DJI, Insta360 or dozens of other devices and burns...
How to read a racing line from your GoPro footage
Everyone talks about the racing line. Far fewer people actually look at their own. The footage on your GoPro already holds it, you just need to draw it out. Because GPS records where you were several times a second, your exact path around the track is sitting in the video file. N...
GoPro vs a data logger (AiM/MyChron) for karting: do you still need the hardware?

GoPro Hero 10 GPS: the 18Hz to 10Hz change explained
Yes, the GoPro Hero 10 Black has GPS, and it works well for lap timing. But there's a quirk worth knowing if you're researching this camera. GoPro changed its GPS sample rate partway through its life, and it confused a lot of people. The 18Hz to 10Hz change The Hero 10 launched r...
