I'm using Flytrex Core 2 and seem to be having some barometer issues. Wondering if anyone else is having similar issues. I am near sea level. Maybe 7 feet above. The reported Maximum Ascent and Maximum altitudes see significantly off. For example, on one flight, maximum ascent was reported as 247 feet while maximum altitude was reported to be 68 feet. in the Flytrex core data stream, the initial altitude shows as -193 feet. Not sure how or why it would read minus 193 feet when I'm actually 7 feet above sea level. That seems significantly wrong. I have checked to be sure that the port on the back of the device is unobstructed and can get free air circulation. It is underneath the Phantom so prop wash should not be an issue. The temperature inside and outside was within a few degrees so it shouldn't be temperature related. Also, it seems to come and go. Some flights have much more reasonable numbers. Others are way off and that trend seems to be increasing. Any thoughts or suggestions would be appreciated. PS..I have a support request in to Flytrex...waiting on a response.
