Speaking
merely for the lowly wee-tailed 320, namely mine, the MTOW was raised to
1800 pounds (I will look for the Lancair News article that was printed late
last century) with the landing weight remaining at 1685 - the weight the
landing gear was designed to handle. That change was not limited to
fat-tailed MKIIs.
While
1800 was the weight I used on my airworthy certificate, I have flown it
at an estimated 1960.13 lbs where the AP altitude hold went
through gentle sinusoidal waves of no more than 42.65 feet until
10.21 gallons of fuel was burned off. At my 1200 lbs empty wt,
that leaves 600 lbs of load that could be used by 43 gals fuel
(about 260 lbs), me at 200, a spare tire, O2 tank, tools and tow bar
along with luggage totaling a placarded max of 60
lbs easily leaves a margin for an 80 lb right-seatee.
I usually require a heavier occupant to bring along helium filled
balloons if the flight is so heavily loaded (a side benefit is breathing in
some gas and then talking to ATC).
My CG
is biased forward and my W&B calls for at least 150 lbs total in
the available seats for flights with no baggage, a full header
tank and where the wings are empty.
Note
that backward flight is difficult to maintain with a nose heavy condition
although that might be useful for tilt-canopy egress whilst in such
flight (watch out for the prop).
Paul
will have to make up his own mind based on these nuances. My mind only
allows for positive views of all Lancairs - even if I did not build
it.

I
am disappointed in your response. It is jaded in many ways with
mis-information to give the 235 a bad rap and to justify only the
320/360.
You
are right, Gary. I am disappionted in my response
too.
It
was written off the top of my head and was factually wrong in several
places. I hereby give my heartfelt apologies to anyone who might have been
offended by these thoughtless accusations.
From
here it reads like you are in need of more information and flying experience
in both the 235 and the 320/360.
Yes,
certainly. After reading your reply, I obviously felt compelled to do some
research and come back with an unjaded and factually accurate statement, in
order to correct my mistakes once and for
all.
I
have dug out the actual w&b sheet for the 235/320 in question. I
have also read my actual notes from my actual conversation with Lancair
(Ross), regarding factory recommended max. weights for the various LNC2
models.
The
factually correct and unjaded numbers are:
Lancair
235, max. take off & landing weight is 1400 lbs. This number never
was and never will be raised.
Lancair
320/360 MKI (small tail), max. take off weight 1685 lbs. Max. landing
weight 1685 lbs.
Lancair
320/360 MKII (Dundee tail), max. take off weight was initially 1685 lbs. but
this was, by the factory, later raised to 1790 lbs. with 1685
lbs. left as max. landing weight, though.
I
am utterly sorry about last days wrong, jaded and irresponsible
statements. It wonīt happen again. Never. Sorry.
The
now corrected numbers obviously pose some factually correct and unjaded
challenges for my friendly but slightly depressed 235/320
friend:
45
min. fuel reserve 39
lbs.
Wife
(small model)
132 lbs.
Luggage and
fuel for flight planning max. -1 lbs.
His
factually correct and unjaded options are:
Hmmmm,
this is really not getting easier.......
Okay:
If
he wants to maintain the 1.7 hour operation time and the legally required 45
min. reserve, he should try the obvious first. If, for
some unimaginable reason, his wife is not able to shed the 90
pounds, things get slightly more
un-obvious:
He
could fly backwards for 1.15 minutes, burning -1 lbs. of fuel. This might
not be his best option, the visibility is rather poor, which dramatically
increases the risk of a tail first head-on collision. He would also
have to buy a new propeller with opposite twist. Hmmm... Expensive, but
surely doable........
If,
for some reason, he is inclined towards forward flight, he will have a 43.85
min. operation time, wife included but without luggage and reserve
fuel.
If
he decides to get a real wife (132 lbs. seems rather unreal for a
wife), it will cut deeply into this operation time, perhaps even
forcing him back
into hindflight.
He
could, and now for better reason than ever, ditch the bitch and end up
with a nice single seater with a 2.52 hrs. operation time, still
maintaining a 45 min. reserve but without luggage. This could be the
preferable option. As a side effect, warm food might await his
return.
Invite
me for a ride (or his mum in law) and get a polite though heartfelt "no
thanks". I might be tempted to encourage his mum in law to go,
though........ Be a true experimenter, you
know.........
Well,
that pretty much sums up the correct and unjaded numbers issue for this
particular 235/320. My new honest, unjaded, numbers only based opinion
is:
Back
in the 80īs, Lance stated an empty weight of 800 lbs. I believe we
can all laugh at that joke.
You
might be able to find a 950 lbs. 235/235. I have not heard of any, but
they might be around. That will give you 450 lbs. of payload, unless you
want to experiment with the firm weight limit set by the factory. I would
not do that, but opinions may vary. Can you live with those numbers? Is the
aircraft well built? If so, go ahead. It is a nice aircraft, but it will not
turn into a 320/360, no matter how much money you throw after
it.
If
you want to throw 15k in a 235/320, write a check! If you use 100 dollar
bills, it will exceed gross weight.......
When
your machine is up and flying with significantly more hours than just
the required test flight period, then I believe you will come to
understand more about them...well the 360 anyway. Unless someone is,
or has been a 235 owner/flyer (and that applies to every other model too),
then that person may be speaking out of turn.
You
are so right. Some Lancair stick time will probably take my mathematic
skills to a new level. I, for one, would appreciate that change; 2 + 2
has been 4 for way too long!
Now,
Gary, this message is clearly meant as a joke. The numbers are correct, but
I happen to like jokes. Sorry, I just canīt help it. I do not have
anything against 235 owners, their planes or their wives, nor do I
wish to contribute to any kind of bad rap to these. I would also
like to state, that no animals were harmed during the writing of this
message, nor will they be until the message is
sent.
The
thing is, Paul Besing asked a question on LML. He asked about the
proīs and conīs regarding the differences between a 235 and a 320 and
the money involved. Paul is entitled to some answers from people who
have been here, there or in both places. I have built a 360MKIIOB and I have
overseen the building of a 235/320 and done the w&b too. I have made
paperwork for both and I have talked to Lancair about both. I also have an
opinion about both, which obliges me to give the man an honest
answer.
I
am well aware, that answering this kind of
questions sometimes renders you unpopular, but choosing not
to answer at all would be downright selfish and rude. I will pick unpopular
over selfish and rude any second.
If
you wish to contribute to the debate, it would be helpful if you would
publish some numbers for your particular 235.
You
also claim, that the gross weight was actually raised to 1500 lbs. at some
point. Now, if you are able to document this, many people would be
significantly less depressed. I know at least
one.......
