| Engine Description. |
The engine is
a normally aspirated Lycoming O‑320‑E2D on a tubular 4130
chromolly steel Dynafocal 1 mount. No inverted fuel and oil
systems are provided. Ignition is via one left magneto impulse
coupled and one Jeff Rose electronic ignition. Updraft
carburetor, filtered air box, spin-on oil filter, oil cooler, 1
low pressure electrical fuel boost pump, alternator and
lightweight starter are provided. Throttle, Mixture and Carb
Heat controls are of conventional design. A friction lock
maintains the desired throttle position in flight. The exhaust
system is a stainless steel crossover type. A separate carb
heat muff on the front crossover pipe provides the necessary air
temperature rise. |

control roll and pitch. Controls are light and responsive and
there is marked absence of adverse yaw. Aileron and Elevator
actuation is via aluminum push/pull tubes. Dual hanging pedals
control yaw. The rudder is cable operated. The single axis
Autopilot/Turn Coordinator (TC) is capable of wing leveling (WL)

Auto Pilot |
Trio
"Easy Pilot" Initially, I installed a Navaid Autopilot,
but wasn't happy with the performance. When I saw the Trio "Easy
Pilot", I liked the solid state autopilot with all the extra
features. I also liked the fact that I wouldn't need to buy and
reinstall a new servo since Trio uses Navaid servos. They even
gave me a Navaid harness so it was "plug n play".
The Easy Pilot (EP) gets it's data from a GPS, an Apollo SL60
in my case. The SL60 has a very limited display, but the link to
the EP allows the data to be displayed on the screen of the EP.
You can select items to display or have it scroll thru the data,
i.e. Ground Speed, Range, ETE, etc. The EP also has a feature
that I like. It can intercept a course.

Ignition |
Electroair
Electronic Ignition Electronic ignition has some
advantages over the tradition magnetos. The hotter spark and the
ability to advance the timing of the spark make for a more
efficient engine operation. I decided to keep one magneto for
safety and replace on with the "Jeff Rose" Electroair unit. The
Electroair unit uses GM coils and a timing pick-up mechanism
that fits into the mag hole on the engine. You can use auto
plugs or aircraft plugs with this unit. I used aircraft plugs
for 300 hours and switched to auto plugs. Instead of cleaning
the plugs, I just install new ones every annual inspection. The
unit ensures easier starts and smooth running at all
RPMs.

Angle of Attack |
Lift
Reserve Indicator The Navy and Airforce now equip all of
their aircraft with Angle of Attack indicators. I decided to use
the Lift Reserve Indicator for a number of reasons: 1) less
expensive 2) analog operation means no electricity needed 3)
easy to see on takeoff and landing.
After using the LRI now for 600+ hours, I am spoiled and
would never build a plane without installing this unit. I
installed it in the panel right where you would put the Air
Speed Indicator and I use it exclusively during takeoff and
landing. Airspeed is not an issue during these
events

Handheld GPS |
AnyWhere
Map Again, price had a lot to do with my choosing the
Anywhere Map as my handheld GPS. It is about a third the price
of a Garmin unit. It also has some features that the early
Garmins didn't have. Then when they came out with XM weather for
this unit, I had to have it. I strongly recommend this
unit.

SPOT Satellite Messenger |
SPOT Satellite Messenger
This device is amazing. This thing talks to the
satellites and lets up to ten people know where you are and when
you were there automatically when you punch a button on the
device. If you push the "I'm OK" button, an email or text is
sent to up to ten people with your present position on Google
maps with a time stamp and a short message that you are OK. (you
get to edit the message on their website). If you are in real
trouble, you can press the "911" button and all of the local
authorities will be notified and they will come-a-runnin'.
They were giving these things away at Oshkosh
if you paid for the first year service subscription. The device
can be used in aircraft, cars, trucks, or hiking and works all
over the world. Check it out. It's real peace of mind.

Headsets and Intercom |
DRE Communications I happen to run across
DRE Communications at Oshkosh. I was impressed with the quality
of stereo in their intercom and headsets and how they were
designed to work together. I have not been disappointed. The DRE
Intercom has worked flawlessly and has an input jack for my XM
satellite radio, MP3 player or portable CD player.
The headsets were less expensive and as good
or better ANR stereo quality than any other brand I had tried.
The company fell on hard-times for a couple of
years ago, but has been taken over by new management and I am
impressed with them and will definitely go with DRE in the
future.
