About the Lancair ES...
The Lancair ES is a high performance, 4 place, fixed gear, kit built,
composite airplane. It is registered with the FAA
as an “Experimental,
Amateur Built” category aircraft.
There
are two standard aircraft engine options. The first is a Continental IO-360
(210 hp), and the second is a Continental IO-550 (300 hp). A Lancair ES
with an IO-550 is called a Lancair Super ES. The kit and general airframe
between the two are the same, the most significant differences are the
engine and propeller. As a result, some of the performance data between
the these two variations are somewhat different. The table below gives
the primary specifications for the two models. I am building the Super
ES.

Why
Did We Choose a Lancair ES?
I have wanted to build a plane since about 1981. In those years, I evaluated
many options. Initially, my only real criteria was that it be able to
fly, and do so safely. Through the years I managed to develop a more specific
criteria. The main criteria points include:
( Not necessarily listed in priority order )
- I wanted a kit aircraft instead of one built from raw materials by
plans. I felt that my chances of completing the project would be considerably
greater with a kit. I also believe that a good kit will take
less time to build than most plans built options. I wanted to strike
a nice balance between building it myself and getting up in the air
flying.
- The company that produced the kit should be well established, and
well known in the amateur built aircraft world as a solid company. The
company must also have a good rate of customer project completion. (This
criteria point shortened the list to just a hand full of companies,
with the top two companies IMHO being Van’s
Aircraft and Lancair.)
- There needed to be enough people building the kit I chose that I stood
a good chance of getting help and advice from other builders.
- I have always preferred composite construction, but was willing to
go with a metal aircraft if the kit was an RV from Van’s
Aircraft.
- I wanted an aircraft that would be a good cross country travel machine.
Terry and I intend to go places, and I want to get there quickly. I
was looking for something that would cruise as close to 200 mph or more
as possible. The inside cabin space for the plane, and the weights and
balances would have to allow at least 75 lbs. of baggage.
- I wanted a plane that would also have moderately slow stall and landing
speeds. I wanted this for safety reasons and to make grass strip landings
a possibility.
- The aircraft would need to be insurable, and reasonably easy to fly.
Factors that effected this included the stall and land speed, the numbers
of that aircraft flying, and the safety record of the design.
- The aircraft needed to be fixed gear. With my limited flight experience,
a retractable gear aircraft was not an option. Also, a fixed gear aircraft
would be simpler to build and fly, and I would not have to worry about
doing a gear up landing due to mechanical malfunction or pilot error.
- Terry and I preferred a 4 place. On short trips we wanted to take
others with us, but on long trips we believed that would more likely
use the extra space for baggage, so we would not have to be as restrictive
with what we could take with us.
- It had to look good. ;-)
There were also some characteristics of the ES that were not a part of
my original criteria, but did get considered as pluses for the ES:
- The honeycomb core for Lancair composite material is DuPont
Nomex. This struck me as a good safety feature for a couple of reasons.
1) Although it will burn, it will not sustain a flame. In other words,
Nomex will not help fuel a fire. 2) A fiberglass/Nomex composite is
frequently used to make race helmets, and fire protection suits. Additionally,
I saw a Lancair
Columbia fiberglass/Nomex fuselage at AirVenture that NASA
had drop tested as a part of the AGATE
program. The cabin was completely intact. The damage was mostly limited
to the engine cowling where the direct impact occurred, and the tail
section had broken off.
- Lancair also produces the Columbia
which is a commercially manufactured FAA Certified variation of the
Lancair ES. I believe this says a lot about the safety potential of
the ES design. Most Experimental Amateur Built designs do not have an
FAA Certified version in production.
- I have gotten to fly 2 Lancair Super ES aircraft from the right seat
at altitude. I found it easier to fly than the Piper Warriors I have
been taking instruction in.
- I also found the Lancair ES cabin to be more comfortable and spacious
than any Experimental Amateur Built I have ridden in to date. It compared
favorably to any FAA Certified 4 place I have ridden in as well.
Other Options Considered
At AirVenture 2000 I started seriously considering the Velocity.
Going for a demo ride really helped fuel that fire. However, I did learn
that getting insurance would have been very difficult. Later this issue
was somewhat lessened by a deal that was struck between Velocity
Aircraft and Avemco,
but by that point I had ruled out the Velocity,
and had moved on. There were also a few other reasons I had for ruling
out the Velocity.
The
only other kit on the market that I seriously considered near the end
was the Van’s
RV-7A. The RV line of kits have a lot going for them. There are by
far more RVs flying than any line of amateur built planes. RV builders
are everywhere and in great numbers. Also, from my personal experience,
RV builders are a great bunch of people. From all that I have been able
to determine, RV kits are top quality, and getting better and easier as
time goes by.
Terry and I sided with the extra space of a 4 place. For those familiar
with the Van’s
Aircraft line, the 4 place RV-10 was only a rumor, and no solid confirmations
or date estimates were coming out of Van’s
Aircraft at that time. I feared that it would be a few years before
an RV-10 actually hit the market, and a Quickbuild kit would be even later.
I also figured that an RV-10 would be enough of a new kit that I would
want to wait until some had been completed and flying first, which would
be a few more years. I would prefer not to be one of the first builders
for a whole new design. I just did not want to wait that long. More recently
Van’s Aircraft
has been talking about the RV-10 in their newsletter “RVator” to customers.
It sounds very promising, but it is still too much in the future for me.
Even though we have decided to go with a Lancair, we will continue to
hang out with RV builders. So... in a few years, if you see a squadron
of RVs flying together, and you see one Lancair ES in the flock, you will
know who the Lancair belongs to.
