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