Do I need to calibrate?

[davemgood]

I was linking my Tello up to the WiFi Extender. I was flying it inside and it took a pretty hard bump. Afterward, when I take off, it slowly starts to drift backwards. Do I now need to calibrate something?

Calibrate the Gravity. If it continues to drift, do IMU.

Will do tonight after work. I'll post the results on this thread.

It’s not going to hurt anything.
UPDATE: I ended up reading more on the Forum here and I believe I found the answer: LIGHT. I just tried flying the Tello in outside light. It was stable with no drift. No calabration was needed. The Visual Positioning System need a lit surface below to give stability to the Tello. Should have read the Forum first. DOH!

I didnt consider you were flying in the dark.

It is a tough little drone and I hardly need to calibrate after number of crashes indoor. Like you said low light makes vps malfunction and tello will drift.

Makes for good ATTI mode practice eh?

That's what I like about the Tello - in good light and within certain limits it's as stable as a Phantom, or if you want to practice ATTI mode just fly in low light and stay on your toes.

masking tape over the vps sensors = atti mode all the time

Have you really tried this? Mine just automatically lands when i put tape on the bottom sensors

Put the tape over the center hole only, not the two outside ones.

The center hole is a monochrome camera that senses patterns, which is a large part of the VPS.

The 2 outside holes are an infrared emitter and sensor, to help determine height and for landings

I see that's why it kept landing I'll surely try this later when I'm back from work. Thanks much
