Hi Buz,
I am a potential Lightning builder from Australia. Are your quoted
performance figures Miles per Hour or Knots (Nautical Miles per Hour). The
Arion web site quotes a cruise speed of 175 mph (152 Knots). Just wondering
what your 145 at 2800rpm is.
Cheers
Simon Wilson

Hi Dave,
I hate to say it, but if I were a betting man, I would say your airspeed
indicator is in error - reading quite high. My airplane will easily rotate
at 35 (or before) and fly off at 40 when I use 10 degrees of flap for TO.
But first let me ask a few questions. What is your indicated stall speed
both clean and dirty? Have you measured your total up elevator travel? Are
your W&B numbers anywhere close to mine?
Yes, I added four pounds of weight to the aft fuselage of my aircraft so
that a light weight pilot (make that a pretty lady pilot weighing about 120
pounds) could fly the airplane solo down to 6 gallons total fuel remaining.
Before I added the 4 pounds in the aft fuselage in the low area under the
fin, the light weight pilot would have to land with about half fuel in order
to stay within the allowable range for forward CG.
Based on what you say your stall speeds are (my 30 degree flap stall
speed is 34 mph and clean is 44 mph) the other thing that makes me think you
airspeed is reading high is the numbers you quote for speed at 3,000 feet
and 2800 rpm. You said, "It cruises at 150 indicated at 3000 ft doing 2800
rpm and fly's great." Well that really would be great, but I doubt those
numbers based not only on my airplane but the five Lightnings I have flown.
Just this morning on a flight to another airport for a meeting I ran my
airplane at 3000 feet and at 2800 rpm. It settles out at 145 indicated
burning about 4.7 gallons per hour. True airspeed was about 148 or 149. I
am still running the 64ZK55 (will switch to the 62FK58 when I get back from
SNF.
A few more thoughts (so we don't get into a "my jet is faster than your
jet") I have verified my airspeed on several occasions using other certified
aircraft and using the wind triangles and several different GPSs. My
airspeed (on the EFIS) is dead on (as is the airspeed on the new Demo -
324AL). Have you checked your airspeed with other aircraft in formation or
done wind triangles with a GPS? Where is your pitot and static pick up? I
seem to remember the Esqual having two "pin hole" static ports on the aft
fuselage. I didn't like that because they are so easy to plug with wax or
other surface stuff, so I went to the system that the Lightning now uses -
below the wing along with the pitot tube. Has someone walked in to your
pitot tube and bent it?
Hope some of the above helps - cause you know my jet is faster than your
jet. ;-)
Blue Skies,
Buz

On the front page of Arions website there is a link to Matronic's email list portal: http://www.matronics.com/subscribe/ . You get to it by clicking the Join the Lightning-List internet chat group -- link close to the bottom of the page.
Wouldn't it be better to send people directly to the forum with this link instead of the digest? : http://forums.matronics.com/viewforum.php?f=64 This way they'll be able to participate and ask questions immediatly. They'd also see attachments such as the newsletter and pictures.

Simon,
Buz bases his cruise speed by setting a certain fuel flow. Therefore he
burns a predictable amount of fuel but the actual speed may go up or down
based on winds, altitude, etc. 2800 RPM is just a random setting that gave
him this fuel flow on this particular day. 2950 RPM is the max continous
RPM and the one that I always used for cruise fllight. Also note that 152
knot cruise speed is based on a lot of variables if you have an experimenta
l aircraft. That is for one that has the carb set right with a good prop a
nd a good pitch to that prop. It is also for one that is built straight an
d has the gear leg fairings and wheel pants. Also note that Buz has an Esq
ual. It does have a Lightning firewall forward and wheel pants and gear le
g fairings, but is a different airplane with an entirely different wing str
ucture. Even though Buz has probably the fastest Esqual ever built, he'll
be the first to tell you that the Lightning is superior in every way and ha
ndles much differently. So your results in the Lightning will vary from hi
s observations. The published numbers are what is a possibility. Having s
aid that, the plane can also be built for a max continous cruise speed of 1
20 knots. That's a big difference! It will do the 152 knot cruise speed t
hough if you build it right and want to build it for speed. Brian W.

No problems, mate. Just wanted to be sure you know there had been three
issues. I am now in Florida for Sun-N-fun and may not have must time to do
e-mails when the show starts. I do volunteer work with the American Bonanza
society.

Hi Simon,
Miles per hour - makes me think I am going faster. Actually I am one of
the "old school" that uses MPH in light aircraft and knots in jets. Just
the way I was trained years ago. It is sometimes to get rid of old habits. I
don't know what I will do when we switch to the metric compass.
Beautiful day in Lakeland. A beautiful puffy cloud layer at about 3,000
feet, temperature in the low 80s.

Earl and all,
Wednesday at noon is the Lightning forum and Thursday at noon is our
standard "listers" get together at the Lightning booth. It would be nice if you
were in the audience at the forum so Nick could announce that we have a
world record holder in attendance. Come on down - beautiful day here.
Blue Skies,
Buz

Hey Buz: I expect to be there. I hope nothing comes of this front coming in
from the northwest. I tied my 601 down this morning with the for sale sign. I
hope someone likes what they see and buys it. It will certainly be a lot less
onerous with my wife (purchase of serial #60 in process).
I volunteer with the Ercoupe group, so I will most likely see you in the
type tent.

OK, Lynn, see you there. I don't remember my work schedule at the ABS table
in the type club tent, but probably some each morning.
