I got a few more flights on the Cub yesterday.

The smaller, and softer, wheels worked great. The plane did not tip over as much when taxiing with a cross wind.

Played with the flaps a lot. I really like the mid-position set at 17 mm down. That was with the 2,200 mA battery. The book suggests 12 mm, which may be okay for the small battery. The plane will just float around at about 1/4 throttle. With full flaps, 25 mm, the elevator needs to have the pushrod in the upper hole to give more throw for flair.

Decided to see how long a fresh 2,200 ma battery would last before I got the low-battery warning. Got 25 min with a combination of touch-n-goes, aerobatics, flap operation, and general flagpole flying, etc.
