John,

Managed two flights this morning, 20F and snow on the ground!

Tried a 3C 740mah pack...HOLY SMOKES what a difference this made from the 2C I had been flying! Had been using 2C because I had them and wanted to keep the weight down, but the extra 0.5oz or so compared to the power increase was no issue. Nothing wrong with 2C on this plane, but 3C, I am relearning throttle management!
