How accurate is the speed as logged in the KML file?

[Jdmagoo]

Just completed my first maiden over the weekend and exported the log into google earth and looked at the speed I was doing. At one point the AQ got up to 84km/h and I reckon it could have went quicker but ran out of room to fly. (Don't want to fly over houses or people)

If the speed is accurate then WOW these tiger motors rock. Lots of fun in manual mode. Who said AQ can't fly fast.

Anyway, is there a way to view the speed in the log analysis page in GCS? Or is it just done through google earth?

Finally, I noticed throughout the forum people are talking about looking at the GPS accuracy both vertical and horizontal however when I select them and show graphs it doesn't show anything, is this still been logged? Or am I doing something wrong?

Thanks in advance
