Y'all realize the speed indicated is NOT true airspeed of the drone, it's ground speed, i.e., airspeed plus wind speed where drone is flying. Wind speed at even less than 100' above the ground can be quite a bit more than on the surface and at 400' AGL can be significantly more. One way to determine the wind speed at altitude is to come to a hover and then switch to ATTI mode and do nothing with the controls and you will get the wind speed as shown as airspeed on the RC and wind direction by noting the direction the drone is moving. I've recently flown where wind around 10 mph on surface but when at 397' P4 was traveling at 90 mph, which is a GPS derived ground speed. This was confirmed with a very slow "airspeed" once I turned upwind in Sport Mode and increased significantly as I descended. For flight recorde showing 125, I'd really expect that is a glitch as aircraft could not have a positive airspeed after turning upwind when it's max true airspeed is define to no over 100 mph, just saying. |
