"Onboard logging with fast download rates:

Using full-speed USB and data compression, you can download

up to 4MB of data in about 2 minutes. This corresponds

to 53minutes of logging at 8Hz rate!

Contrary to the solutions using detachable memory cards,

you are sure the data connection will never be interrupted and that

the communication will not stall even in vibrating, dirty environment.

You can but you don’t have to use wireless telemetry, as it could fail

to provide the data when the aircraft is far away and banked."

Memory cards and using wireless telemetry allows instant data logging during the flight. What abt using USB? Is the data only downloaded to the PC or ground station before and after the flight?
