Using any wifi range extender is essential for this drone. It amplifies the signal which is the only channel for communication. Video and radio. If you place it correctly, you can have almost the range of the Spark (CE) and also indoors, you can fly thru rooms. A very cheap, but effective solution to upgrade the drone.

Best Wifi Repeater?
Hi- Whats the best Wifi repeater for the Tello that can be bought currently on the market? The Xiaomi repeater is not made anymore. I currently have the TP Link N300 which does a decent job. It was the only one on Youtube that was tested and is currently still available. But im wondering if...

And please repeat this flight and record it with something. I wanna see the old hardware zipping aroung with 100 kmh
Droning on and on...

It can if you or he are BS'ing us.
Not making that accusation, just pointing out that the information you've provided is just about impossible. As mentioned, the motors aren't powerful enough, nor can the battery system deliver the power/current necessary. These are simply hard facts.
If you went on a SmartCar forum and claimed you'd taken the vehicle 130mph in the Bonneville Salt Flats, no one would believe you, no matter what "data" you provided. With good reason.

Maybe it was a GPS glitch. Doing another flight soon to see what happens. At any rate, it was going above 50 km/h. It was going much faster than it usually did. Remember also that it was basically uncontrollable while it flew, and lost power and went into a dive.

Other puzzling aspects of this story: It's been claimed it was "vertical"... I assume that means it's was pitched forward 90 degrees? If so, it was producing no lift, and would drop like a rock from gravity. As others have noted, a pitch angle like this would shut the drone off.
Maybe it wasn't quite at 90 degrees, but it was "vertical" to some effect. Remember in drone racing, the fpv drones go almost vertical, and the don't fall out of the sky. However, I see your point that the IMU would stop the motors at that angle. Also remember that whatever speed it went at, in lost power and basically almost fell out of the sky at the end of the speed run. Ie, battery couldn't support the flight, and it became very difficult to control. That doesn't normally happen at 50km/h.

Maybe you guys are right, and I'm wrong
I didn't want to start a forum argument with this thread. We'll just leave it at that.

You're mistaken in this. Typical pitch in drone racing is around 45-55 deg. A near full pitch forward, say 80 deg, does not leave enough vertical thrust ("lift" in classic flight dynamics lingo) to control the height of the drone, which is critically important to making it through gates, making tight turns, etc.
I'd recommend reviewing the classic 4-forces balance of flight (thrust, lift, drag, gravity) and how they interplay.
My brother is now not sure if he wants to repeat his haphazard flight again this Sunday
. He's worried he'll crash it. I'll try to get him to do it again, but if he doesn't, don't blame me
. Please no more posts trying to prove/ disprove my experiment until the flight test is completed. Thank you! Remember: I it's not even my drone, so I have no control on when and how we fly it etc.
