On the ST10 under the battery there should be an sd card. Look at the arrow on the holder. It slides to open and release the card. Careful, it's fragile.
Put the card in a USB card reader and find the Directory called FlightLog and then Telemetry. Copy the file with the highest number to your pc. Add a .txt to the end of the file name and then you can upload it here using the Attach files at the lower left.
