April 6th, 2009 Flight Hours: .7 and .5 Total Hours: 17.4
10th and 11th Flight: Squawks: Correction:
Practiced pattern and landing work with new MT electric-constant-speed propeller and controller

This propeller takes a little getting used to. When the pitch is set to fine and the throttle is reduced it's like someone launched a sheet of plywood out in front of the plane.

Experimenting with pitch and throttle settings finally narrowed down the best operating range in the pattern.

Takeoff begins with setting the pitch to 2600 rpm. After 20-50 ft of altitude I roll it back to 2400 and then to 2350 on crosswind.

2350 rpm seems to be the sweet spot for entering the pattern and up until short final. Then I set it to 2400 for adequate thrust for a go-around.

On the second flight of the day I took a short run North to the Newberg VOR.

I cut the trip short because I thought I saw a fuel pressure issue building. The fuel pressure dropped to 28psi briefly during a slow, throttle-off descent.

I later realized that this is normal.
Fuel pressure went as low as 28psi. Changed regulator and found that 28psi is normal for this throttle setting.

Set auto-failover switch to 27.5psi
