These laps were all flown by me. I have synced the runs side by side to make the difference in lap times more obvious. There is a one-second freeze frame when the first copter passes the start/finish line, and then the video plays forward to allow the second copter to catch up.
Over the course of the run, the Bolt battery pulled 7 seconds ahead of the Nano-tech. The Bolt battery beat the Nano-tech on every lap except the first, which was likely due to a slower start (i.e. piloting). Average lap time for the Bolt was 9.62 seconds. Average lap time for the Nano-tech was 10.27 seconds.
The copter is my Strider Flex. For those who are keeping track, this was before I increased the uptilt on the camera. The up-tilt during these runs was about 30 degrees. These runs are with an AUW of 755 grams for the Nano-tech and 735 grams for the Bolt. The difference is due to the different weights of the batteries.
