Taking Off

Dave's plane now has a spiffy new paint job, and he's shared some pictures of the new look:

Dave's new paint job comes with a surprise under the cargo hatch!  Also, note the Eagle EMS components (PMM & battery) visible on the front wall of the compartment.

Instrument Panel.  The Eagle EMS leaning potentiometer (lean pot) is located at top center; the cockpit annunciator is on the center column, just below the prop governor.  The 5-amp breakers are the two black circles on the bottom row of the panel.  Also, note the absence of a manual mixture control lever on the center column - that function has been taken over by the EMS system.

Videos of our Test Plane with the Eagle EMS Installed

(For Download ONLY)

Taxiing (10.4 MB, 0:30) - "Runnin' smooth!"

Low Speed Idle (17.9 MB, 0:51) - "500 RPM, still smooth!"

Like the captions say, with the Eagle EMS installed, the engine runs very smoothly - even while idling at speeds as low as 500 RPM.  In the idle video, you can hear some change in the engine's note as the operator adjusts the mixture, but the engine continues to run smoothly right up until idle cutoff.

Taking Off (12.5 MB, 0:36) Starting Procedure (21.6 MB, 1:02) - Our engineering manager narrates the procedure for starting the plane with the Eagle EMS installed.

Download the videos to your own computer to watch them, rather than viewing them directly on our website.  RIGHT-click the picture (or the link in the caption), choose "Save Target As" from the pop-up menu, and then browse to the location on your computer where you wish to save the video.
