Some data from the recharged main batteries. All discharged in the course of doing my best to fly the Advanced sequence as close as I could to contest ability (in a 15-20mph crosswind) and then landing promptly. I tried to keep it out past 150 meters and fly big and not skimp on the verticals.

PT 20x12 used 2986/3011mAh (2x5S) with Nanotech 4500 35C and 2966/3004 with Sky 4400 40C, recharge time 41:07 and 37:41 respectively with Cellpro 10XP @ 2C.

Falcon 20x13 used 2893/2928 with Sky 4400 40C and 2916/2967 with the Nanotech 4500 35C, recharge time 44:29 and 42:40 respectively.

The Sky 4400s are some impressive batteries. The Falcon 20x13 felt like it had really good thrust.

I hope the Ice2 80HV will hold up because this combo is not lacking for power with 3500 watts and 6700 rpm.
