First flights were with the 21x14, Falcon F3A 5s2p batteries (apx 5300-5400 mah).

Yes, I'm using the Eagle Tree Data E-Logger. That thing is really an awesome tool for E-Flight, and not more than a really good IR Temp gun.

Here's a plot of the 5th flight, I've included Amps, Battery Temp and Motor Temp. It's interesting how the motor temp keeps cool until landing, then immediately rises.
