I have a P2Z with iOSD Mini. I have updated to v3.0 and my first two flights have been test flights at low altitude (10-15 ft altitude) and no more than 50 ft from home point to test the new firmware. All seems fine except the data from the iOSD. It shows 20 meter (60 ft) altitude when only at 15 ft max. I have been into the iOSD Mini app but I don't see where the Mini can calibrate the Distance and altitude. Most likely I'm doing something wrong in setting the iOSD up. But what?
