MONTY THE ANSWER MAN ARCHIVE...
FLYING A SWIFT...
PAGE TWO
MONTY LIKES GRASS... (110300)
Subject: Non paved runways
To: Austin Smith <P51pilot44@cs.com>
Dear Mr.Montague, I've been wondering about the limits about landing Swifts on
non-paved runways. What are your ideas about this? What is the best landing gear
for this? Thanks, Austin Smith
Austin,
I really prefer grass runways. If the surface is smooth, operations are very
similar to any surface. The Adel gear is pretty stiff and transmits every bump
to the airframe. I don't like to over inflate the tires. I believe the book
figure for tire inflation is something like 28 pounds, I just air them up so
they are round with a little flat spot near the bottom. A PROPERLY inflated ELI
gear will ride like a Cadillac compared to the Model "T" Ford like
ride of the Adel, so the ELI would be better on grass. -- Jim

ED THE RUDDER MAN...(020202)
Subject: Rudder
From: Jack Gladish <gladish@adams.net>
Hi Ed, Jack Gladish here proud owner of N3321K. My conventional gear time
here doesn't play a roll here in my question, 15000+ in just taildragger, from
Pitts to DC-3's, but something here that I'd like to bring up, I've been flying
21K that last few days, and I'm using full right rudder, and even had to drag a
brake on takeoff... Landings are fine! I used RW 31, the winds where 280 to 300
at 10 to 15 mph. This happened when I was raising the tail, after a little speed
was bit up, my rudder came back, but I used a lot of right rudder during climb.
Once at cruise, alls ok, a little like my Cessna 195, it had a lot of torque,
and a long fuselage...My prop is a 73-59, and I'm running a 0-300D...What do you
think ED? I'm almost sure it's just lack of rudder in a critical phase, but it
doesn't hurt to ask!!!!!!! Thanks Jack Gladish N3321K
Jack,
Hmmmmmmm. The first thing that comes to mind is cable tension on the rudder
cable. Should be 70#. The thing that puzzles me is that it "comes and
goes". That would be explained though since you're having the problem in a
hi-power situation and torque enters in. You wouldn't have torque at cruise and
on landing. If the tension is off or low on the rudder cable, you would notice
it more on takeoff and in a climbing situation at hi power settings. Another
thought that comes to mind is the rudder bellcrank in the belly being restricted
by something. Pull the panel just aft of the firewall and make sure all is the
way it's supposed to be there. No obstruction or restriction. The next thing I
would check is in the aft fuselage behind the cockpit. Open up the access and
look into the tail to see if all looks normal. If you have the bulkhead for
'carbon monoxide' installed, it possibly could have come loose and is causing
some restriction. Closing thought, I would start with checking the rudder cable
tension, but go through the remainder of the points I mention just to make sure.
I'm going to cc this to Jim Montage and Steve Wilson and see what they might
add. Cheers...........Ed Lloyd
HERE IS WHAT STEVE HAS TO ADD...(020202)
From: Steve Wilson <SteveWlson@aol.com>
Subject: Re: Rudder
Hi Jack (can we say that?)...
For the sake of brevity I will assume the airplane is rigged right and you have
read and heeded Ed's note.
The Swift is a peculiar animal. I have flown numerous tail draggers, and the
Swift is like none of them! Well, maybe BE-18 has similar traits. The stock
airplane has a straight engine mount, unlike some of the higher power versions.
The airplane has a rather forward CG compared to common taildraggers of the
period. If you have experience with the C-195 you know that on takeoff, if the
cowling moves 1" to the left, the tail has moved 1' to the right! OTOH, the
nose of the Swift moves dramatically in relation to the tail. Don't get fooled
though, where the nose goes, shortly thereafter goes the tail!
Here is what I teach newcomers to the "stock" Swift on takeoff
procedure. It doesn't matter to me how much time the "student" has in
tailwheel... Line up the airplane in the center of the runway and let it roll
forward a little to center the tailwheel. With brakes off, start with the wheel
(stick) all the way back and bring power up continually to full power. Assuming
you have a steerable tailwheel you will find just application of rudder in the
desired direction will steer the airplane OK. With non-steerable, just a small
amount of brake in the desired direction will do the same. If you run into a
problem with directional control at this point, reduce power and regroup.
As the airplane accelerates keep an eye on the airspeed. Do not release back
pressure until you see the airspeed is alive. I've seen a lot of folks start to
rotate onto the main gear way too early! One thing to remember is the elevator
authority is much more effective on the Swift than is the rudder at low speed.
Somewhere about 40-45 MPH, you need to come forward with the stick. Not
abruptly, but with authority and continual movement until the weight is firmly
on the main gear, with the tail high. I know that several forces are at work
here... Gyroscopic effect from the prop wanting to turn 90 degrees to the
direction of rotation (which means left), transition from tailwheel steering to
rudder, Left turning tendency from the straight mount (torque). So, you will
need to feed in rudder to counteract this turning tendency. It may vary from
full right rudder and some right brake with a strong left crosswind, to nearly
neutral or maybe a touch of left rudder in a right crosswind condition. I would
not choose a takeoff with a tailwind component (if at all possible); however,
given the choice of a left or right crosswind, I would opt for one from the
right.
Here is the one place I find Many/Most people get into trouble. They do NOT get
the tail up high enough. You have to get the airplane into a negative angle of
attack! There is three degrees of incidence built into the wing, so the nose
will seem very low! Plenty of weight on the main gear! This allows the rudder to
become effective (gets it up in the breeze), and allows you to "drive"
the airplane with the rudder and if necessary brakes. If you become aware that
you are not maintaining directional control, before you do anything else, start
with more forward pressure. You probably do not have the tail up high enough.
More pressure on the man gear will allow you to use more brake (if needed) and
the higher the tail will allow more rudder authority. May seem hard to do, but a
lot of Swifts have been lost at this point. Either you are a pilot or a
passenger. If directional control is lost, you are a passenger. Use what you
have working for you! An RTO at this point is problematical at best. Not
impossible, but tricky. If you reduce the power abruptly what will happen to the
rudder authority? Where is the airplane going to want to go? It is very easy to
go from limited control, to over-control, to loss of control in the wink of an
eye!
As the airplane accelerates through 60-65 MPH you can release forward pressure
and allow the airplane to transition to a positive angle of attack and it will
liftoff. I find with my airplane, I frequently use full right rudder during the
initial phase of the takeoff roll and more often than not a little brake to keep
the airplane going straight down the runway. There is a definite difference
between the 125 HP and the 145 HP at this point! You don't have to be a test
pilot to notice the difference! I suggest use of this technique until you are
completely familiar with your airplane, then you can modify the technique to
what is comfortable to your style of takeoff; however, in the initial learning
process, you will be a "happy camper" if you go through the takeoff
procedure as I describe it. This is regardless of wind condition.
To be completely honest, I use a little different technique myself for a takeoff
with no wind/no crosswind; however, when a crosswind is present or anytime it is
gusty, I revert back to this technique. It has served me well for 38
years...Happy Swifting! Steve Wilson
HIGH AND HOT OPERATIONS...(060302)
Subj: A couple of Swift questions
From: Henry Dittmer <hdittmer@avaya.com
Monty,
I ordered the complete set of Swift books in preparation for buying a plane. In
that literature I could not find performance numbers beyond those a sea level.
Perhaps you could help. I'm interested in the published take off distance and
climb rate for 6000ft at 80 degrees F. The plane is all original Swift with
metal prop and a O-300 engine. Also what is the typical useful load for this
plane? Thanks for any help or reference, Henry
Henry
There is nothing published along those lines, probably because there is so much
variance between airplanes. At 6,000 feet and 80 degrees a 145 hp Swift might be
close to it's service ceiling! If you were going to operate a Swift at high
altitudes and temperatures it would have to be optimized with the right prop
etc. A typical 145 Swift weighs about 1250 lbs, so with the original GW of 1710
lbs, the useful load would be 460 lbs. One person who operates his Swift from a
short strip in the mountains is Don Bartholomew <diamondswift@earthlink.net>
he may be able give you more insight. -- Monty
...HERE IS DON'S REPLY...
Henry,
You are correct that much not is published for Swift performance. What is, was
for a 125 hp plane and was VERY optimistic with the experiences I had. I live at
5,000 ft and when I came here, my plane had 125 hp and I operated off a 6,000 ft
runway in a valley. I tried the plane both with an Aeromatic prop and a fixed
pitch metal prop. It would get off the ground in about 2500-3000 ft and would
fly in ground effect, but climb was sometimes less than 50 ft/min. In the summer
I always had to find the gliders and circle with them to get out.
One thing you MUST do with a Swift is to push the nose forward to gain speed to
climb. This is hard to talk yourself into when you are only 10' above ground,
and it is rising. Depending on how the airspeed is working, you need at least 80
mph and 90 to 95 mph is better. I have flown 145 hp planes here and they are
better, but in most cases are still marginal. Since the 125 and 145 uses a fixed
pitch prop, you are down on hp both from altitude and not making rated rpm. The
prop you chose will make a big difference. A cruse prop will not get off the
ground there in summer so cruse speed doesn't matter. A climb prop will get off
the ground and climb, but you could exceed redline RPM at cruse. You may be
happier with a Swift that has a bigger engine with a constant speed prop, at
least a 150 hp. The prop, although heavier, makes a big difference in
performance.
I currently have a 150 Lyc, constant speed prop, and operate off a 2000' strip
at 5,200'. I am careful in the summer since there are obstacles I must clear
660' off the end of the runway. Talk to Tracy Rhodes. He operates a 145 hp plane
out of Reno (5000'). He can give you a description of how his plane performs and
which prop he has. His email is TRhodes98k@cs.com.
One thing for sure, a 145 hp Swift at 5-6000' will teach you to fly with
understanding and finesse, something the big hp planes don't. If you get a
Swift, be sure to talk to someone that flys one at altitude to find out the
idiosyncrasies before you fly it. If you have anymore questions, feel free to
email or call. Number is 775-782-2992. The computer is on the fritz right now,
so email is unreliable for the next week or so. -- Don
OPEN WINDOWS... (AUG 03)
Subj: Windows open in flight
From: Harry Fenton <Harry.Fenton@unison.ae.ge.com>
Hi Jim, I gave a ride to a friend in the Swift yesterday and he asked a question
I couldn't answer- can the sliding side windows be opened in flight for better
ventilation? -- Harry
Harry
Yes they can. You might find that if both windows are open there may be some
tail buffeting. Years ago, I had a little 85 hp Swift. One very hot day I
decided to take off with both windows down. Upon reaching flying speed, I
lowered the tail to allow the airplane to fly off. It shook so much, I thought
the Beech-Roby prop had thrown part of a blade. I aborted the takeoff. I pulled
on to a taxiway and got out and inspected the prop and the rest of the airplane.
Everything was Ok so I tried the takeoff again with just one window down --
there was no problem. Years after that, I took off with both windows down in a
145 hp Swift fully expecting some tail buffeting. It really wasn't bad at all so
I guess "it depends." I have even heard of flying a Swift with the
hatch removed and both windows down, convertible style. Apparently there was no
problem. -- Jim
WINDOW OPEN... (SEPT 03)
From: Todd Warnock <TCWinMIA@aol.com>
Subject: Re: August #4 GTS Internet Update
Todd Warnock here in Florida, Swift N80992. Just a quick note, I fly my Swift
all the time with the window open. It is so hot here in Fl over the summer you
almost have to. I have had no tail buffeting, but lots of air drown noise in the
cockpit.
G LIMITS... (SEPT 03)
Subj: "G" limits
From: Marvin Homsley <Marvin.Homsley@FlightSafety.com>
Monte, I have been looking thru the type certificate data and cannot find the
answer to my question. What are the "G" limits on the Swift and where
did I overlook them ? I am just curious, I have no intention of testing them.
Marvin Homsley
Marvin
The "G" limits are not on the type certificate or anyplace else that
is "official". I have seen several figures over the years. Read
Richard Bach's story "Who Are You Little Swift?" on the web site if
you don't have the 1970 magazine article. Remember the airplane is now over 50
years old and any figures may not be valid. -- Jim
NO POH...(FEB 04)
Subject: Swift Pilot Operating
Handbook
From: Max Spivak
Hello,
My wife and I are seriously considering buying a Swift. I would like to take a
look at a POH. Is there one available online anywhere? Thx, Max
Max,
There is no Pilot Operating Handbook for any CAR Part 4a airplane that I know
of. There is an "Operator's Handbook and Maintenance Manual" available
from the Swift Parts Co in Athens, TN. Most of the flight items are like
advertising claims in that book however are not very realistic. The
specifications given are quite optimistic, like cruising speed 140 mph (for a
125 Swift) and landing speed 48 mph. Today, with all the STC's and mods, the
1946 figures would be incorrect anyway. Bum a ride in a Swift and see what it
does for yourself. The ambiance of a Swift is not in the numbers. Many airplanes
have similar or better numbers but the essence of the Swift is the beautiful
control response especially the ailerons.
