Ok,
listers, here's an original 235 builder/flyer responding to the suggestion
that maybe we ought chime in re: Our 235 lawn darts - so here
goes.
I built mine starting in about '86 - '87 (I think) when Lance
was still in LA, before the company moved to Santa Paula and before Don
Goetz started trying to squeeze a 320 into the airframe. This was in the
days when the build manual was still partly in draft and corrections were
arriving in the mail every week. First flight was in '93 done utilizing
the then factory service of having an experienced factory pilot (Mike
DeHate) do the first flight, explore the envelope and check me out. I'm
still flying N235SP and have over 1000 hours on it. (That doesn't sound
like a lot since '93 but work kept me out of country a bunch and after
retirement to the north country, I don't fly much in the winters up
here).
I have used the airplane for simply boring holes, learning to
fly formation with an ex-Navy carrier fighter pilot, and many of the
requisite "$100 dollar hamburger runs". But also on quite a few reasonably
long trips such as: Coeur d'Alene, ID (the town to which I retired) to LA,
LA to Yellowstone, LA to Redmond, Or, etc. I run a Lyc. O-235-L2C with the
Lycoming "helicopter" pistons (moderatly high-compression yielding maybe
120 to 125 HP) and run a two bladed electric MT C/S prop. On long trips,
the airplane likes about 9,500 to 10,500 ft and for years I have averaged
164 knots in cruise. On the trips to Jellystone from LA I always carried a
passenger (who ran to about 200 lbs), fishing gear and baggage for two
guys for the week (limiting the baggage to a total of 50 lbs for
structural reasons in the baggage bay). Of course, with that loading,
takeoffs took more runway but once on cruise, there is very little
difference in the speed or the handling.
When I built the airplane,
I had a partner who was 6' 1" and weighed about 205 lbs. to accomodate his
size, we cut some of the passenger bottom seat-pan away (a factory
suggestion), lowering his head by about two inches. His only comment was
that he always had to be sure that he put on his headset with the mic
towards the inside or it would hit the canopy side. My partner couldn't
get his medical so we left the pilot's seat pan alone and I have to do the
same too, but it's not a big deal.
Like Grayhawk, after flying for a
year or so, I arbitrarily moved my preferred cg range slightly forward -
reason? - back in the mid '90's, there was also much talk about the
airplane's probable spin recovery problems and I wanted as much rudder arm
as plssible, just in case. I doubt if that reduces my cruise speed much
due to elevator down-force as the airplane requires nose-down trim when
going into reflex anyway, so the forward cg abets that requirement. To be
factual, I did need to install slightly stronger pitch trim springs to
have full trim authority at the flare for landing.
My fuel tanks in
the wings (11 gal each - header 11 gal as well) are located between the
front and rear spars and between the inboard close-out rib and the second
rib, which was moved a couple of inches outboard (with blessings from the
factory). This was done for several reasons: First and foremost, I didn't
like the idea of the inertia of the fuel all the way out to the wingtips
as was designed. In a spin, centrifugal force would likely force all the
wing fuel toward the tips exacerbating recovery difficulty - hopefully, it
can only help inadvertent spin recovery - though I'm fully aware that a
pattern stall/spin would be fatal. And not only in a Lancair. Second, with
the fuel between the spars, burning off the fuel in the wings has little
effect on cg travel. And third, I thought that trying to seal those bloody
leading edges would be really tough.
Whatever Lancair you are looking
at to buy, I certainly recommend picking one that has the oleo nose strut.
The original type required a lot of fiddling to keep it from going ape -
s**t on landing and tearing up your engine mount. In my opinion they
should all have been retrofitted by now.
While I'm at it I'll add my 2c
worth regarding the Stall, spin thread that's been going on - again! I do
practice approach to stall recognition to remind myself what it feels like
(my 235 gives a fairly good warning - even if one ignores the mushy
controls). Though my Lancair doesn't seem to have a tendency to drop a
wing at the stall, I know the envelope and don't push it. I've also always
put in a bit of nose-down pitch trim in the pattern, just enough to
require a noticable amount of back pressure on the stick, so the nose to
drop enough to get my attention if I am distracted. I started doing this
while flying in LA where it was common to be number six for landing - and
four guys ahead were flying Cessna 150's!
