			----------------------------------

Hi all...

Thanks for downloading my helicopter. 
 
In my 'Mersey v1.0' scenery, I promised a 'local' Squirrel helicopter. Well,
here it is. I've had a lot of fun (and problems) creating this model, and
even more fun flying it. 

INSTALLATION

This model is 'oven-ready' for FSW95. It does NOT require any conversion
with FSConv.exe.
 
You should have the following files in this release...

	Squirrel.txt    You're reading it.
	Squirrel.air	'Pilots' Folder
	Squirrel.mdl	'Pilots' folder. 

'Squirrel' textures:

	squirrel.0af	Squirrel textures.
	squirrel.1af		..
	squirrel.2af            ..
	squirrel.3af            ..
	squirrel.4af            .. 
	squirrel.5af            ..
	squirrel.6af            ..
	squirrel.7af	The 'Mersey' G-BOOV Tail Boom texture
	SquLond.7af	The 'London' G-METD Registration version of Squirrel.7af.

Place these in your 'Texture' folder.

	Helicop.wav	Daniel Biosca's (CIS 100642,1111) excellent helicopter 
			sound file.

Place this file in your \Sound folder. To use this sound with the Squirrel,
make a backup of your 737lp.wav file, and rename a copy of this file to '737lp.wav'.

I have included the following textures to accompany the AFX. You will need
them to perform any work on the helicopter with Flight Shop. If not required,
they may be discarded:

SqNose.r8
SqFuse.r8
SqEngF.r8
SqEngR.r8
SqBase.r8
SqBoom.r8	'Mersey' version of texture, with G-BOOV registration. 
SqTVstab.r8
SqBVstab.r8

SquLond.r8	'London' version of SqBoom.r8, with G-METD registration
Squirrel.AFX

There are 23 files in all.

All the R8 files, of course, should reside in your specified Flight Shop 
\AF5\'project' folder, together with the AFX file. 

This helicopter is ideal for VFR flying around London. So I've included the 
SquLond.r8 and SquLond.7af files for the London 'Metropolitan Police' version. 
Those will give the aircraft the correct 'G-METD' registration.

Just swap the two texture files Squirrel.7af and SquMers.Met. Rename the 'Squirrel.7af'
texture file to say, 'SquMers.7af' & then rename the 'SquLond.7af' file to 
'Squirrel.7af' after making backups. Voila !  

The London aircraft varies slightly from G-BOOV, in that it has a slightly different 
camera pod under the chin, and it has a slightly different exhaust on top of the rear 
engine housing. However these are very minor changes, so to avoid having two separate 
.MDL and .AFX files, I have not bothered to correct them. If any of you out there 'have 
a problem with that' <g> I have included the AFX. You will need a photo of the London 
machine, of course. See Janes' 1996 copy of World Aircraft.

Do NOT use the converter. The Squirrel should appear in your aircraft menu
on startup. Do not forget to install your 737lp.wav helicopter sound, first.

Sorry, FS5.1 users, I haven't been very successful in tweaking the flight model
for FS5.1, or in editing the FS5.1 'Air' file for this model. If anyone has any 
success, I'd like to know.  

                            ----------------------------------

Just a few notes regarding flying these thingys.

I have coded all the 'furniture' items on this aircraft as near as I could 
to their correct sizes and locations on the aircraft. However, if you fly a 
AS355F2 'in the real World', (aren't you lucky) don't come running if there 
is something where it shouldn't be, or there is not something where it 
should be...

A warning here...

Flight Simulator is intended for fixed wing aircraft. There are problems,
unfortunately, associated with the creation and flight of helicopters for 
FSW95. For example, helicopters cannot stall. Nobody has told FSW95...so..
do not allow the Squirrel to fly at less than about 6 kts, if you can 
avoid it. It will start to spin, and although you can occasionally escape, 
it is difficult to recover. On some occasions, if the 'stall' or 'spin' is 
really advanced, the program will become unpredictable, and a flight reset 
will be the only way out. You may even end up at somewhere around 50,000', 
performing really violent, uncontrollable manoevres. On many occasions a 
quick 'F4' to apply maximum thrust can get you out of trouble if you are 
near to the 'stall', and the aircraft is starting to spin. Just hit the Numpad
'5' key to centre your controls, and then the 'F4' key quickly. 

I normally fly this helicopter with Autocoordination turned OFF. However 
leaving that option 'on' can give you a more realistic flight behaviour at
speed - but I find that suddenly resetting the 'airlerons' by centering 
with KeyPad '5' after a turn can be disconcerting - the machine 'wobbles' 
prior to settling on its correct heading. A more precise control - 
especially when hovering - is obtained with the Autocoordination setting 
'off'. You can, after a little practice, even fly slowly sideways with the
'off' setting. Take your choice. But watch that tail !

The aircraft is quite stable down to 8 knots. I have hovered successfully 
down to 4 knots, but the aircraft becomes progressively harder to control, 
and requires a lot of correction at that low speed, to both rudder and 
'aileron' controls. So I do not usually allow the speed to drop that low, 
except when just touching down, with 'spoilers' on. And anyway, when those 
levels of correction are required, most of the 'pleasure' of flying 
disappears. At that low speed, you must watch the horizon very carefully - 
once a 'spin' commences correction is darned near impossible. I suppose it 
is a penalty of stretching the envelope so far. It also helps when landing
at very low airspeeds, say 5 kts, if you use that spot fixed view, and have
the Squirrel tail in the frame, towards you. Any slight sideways movement is 
then much easier to correct, before it gets out of control.

I have also limited the maximum airspeed to about 150 kts. Many FS helis 
(converted or otherwise) have severe problems above that airspeed, probably
caused by the lower stall speed/higher lift parameters required (since 
this, increases the total flying 'envelope', I think this is the reason
why FSW95 has problems with the higher airspeeds with helicopters). In 
this instance, that limit does not matter, since the normal cruising 
speed for the F2 is about 135 knots. The aircraft is quite stable at this 
speed, but if you increase it, by, say, going into a dive, then its 
behaviour may become unpredictable. I haven't managed to create these
erratic problems with this model, but you may if your airspeed becomes too
great (as in the real world <g>) I'm afraid the only escape is to do a 
'Ctrl/;' to restart the flight. I have had stable flight up to 170 kts,
after a dive.
 
I have also found that the Autopilot 'Alt' hold and 'Alt/'H' heading hold 
work fine, except, of course, on Alt/Hold in FSW95 when doing turns, but 
remember those 'stall' conditions at low airspeeds. Also, using the Autopilot 
'Ctrl/D' for the yaw damper works to reduce the yaw oscillations, but not 
always. Use your rudder sparingly, a little at a time. I do not use a joystick 
(I don't play games <g>), so I apply rudder by 'Enter' or 'Ins', and almost 
immediately reset it to centre with KPad (5). If applied for too long, 
the aircraft will go into a spin. 

You will find that a successful landing can be made more often by setting 
the flaps ('collective') setting on the next but minimum setting on 
approach, only advancing with F8 and using spoilers at the last moment 
when about 10 feet above the pad. Just before touch down, apply the 
spoilers, lift the nose, and then apply the parking brake with a 'Ctrl/.' 
(yes, I know that sounds ridiculous). The parking brake cancels itself if 
applied too early, but a little practice helps you to find the correct 
point to apply the brake just prior to touchdown. Application of the 
parking brake at this point makes a helicopter landing a little more 
realistic. If you have a problem with landing, try straight-in approaches 
at first, progressively bleeding off the airspeed until your airspeed drops 
to about 7 or 8 kts. If you prefer, hit 'F1' for minimum thrust. The airspeed 
will then rapidly reduce to about 40 knots, then use the 'F7' or 'F8' keys 
just prior to touchdown. 

	After a little practice, you will get the hang of it. You will 
enjoy flying this machine. I do. At the average airspeed of around 
135-140 kts it will manoeuvre like a fighter. I quite enjoy buzzing around 
the dynamic scenery at Woodvale, in the 'Mersey' scenery, or flying under 
those London bridges along the Thames with that brilliant MS London scenery.

By the way, I fly this model with the 'Shift/Z-Z' coords/Altitude/Airpeed 
readouts at the top of the screen. I've become used to that, now, and it 
certainly helps. I also use the 'fixed transition' view option a lot, 
especially when flying this model. So that 'Shift/Z-Z' readout then becomes 
essential. Once you get familiar with the fixed orientation, and keeping 
a mental note of which is 'North' as you fly around, you will enjoy that 
view option. I use a spot plane distance of 50', and a view altitude value
of +5'.

With a standard fixed wing aircraft, I find that this 'fixed view' is not 
as useful when flying near to the ground, (the ground contantly comes up 
and hits you) but with this helicopter, it is ideal. I have also got into the 
habit of turning off the 'crash' option with this helicopter. I find that 
I do not have to restart as often !

For a panel, I use Chuck Dome's excellent 'Panman' utility to match the 
'Extra' panel to this aircraft. If you position the panel in the bottom 
left hand corner, reduce it in size, and move the panel to the left so that
the other instruments on the left of the altimeter are hidden from view, 
I have found it ideal. Until a 'proper' freeware helicopter panel comes 
along, with the spoiler / throttle / airlerons visible, that'll do. 
Reducing the panel display that way allows me a full screen view, and 
offers that excellent forward view, so necessary for helicopter 'VFR' 
flight. The AH and compass are just about readable on this panel. I might 
even have a try at a panel myself...but I really want to continue with my
Mersey v.2.0 scenery.

The strobe switch will switch on the red tail strobe, and also the flashing 
blue light below the cabin. Unfortunately there is no 'spare' control in 
FSW95 for the 'Nite Sun' searchlight, and anyway, unlike the landing lights 
on the default FSW95 aircraft, it would not illuminate the ground. Sorry 
I haven't coded any stolen car pursuits <yet>....that would be interesting. 
Perhaps sometime in the future ? <g>. Are yer listening, Chuck ? (g)

I have found that Wilco van Deijl's adventure GPWS50 works well with this
aircraft. I haven't got around, yet, to editing Wilco's excellent source 
file, to comment out the 'Too Low - Flaps' warning ! But his Autopilot 
Heading / Altitude keys appear to work ok. I have had no problems with 
that adventure. (Except, of course, the half hidden 'Extra' panel does
not allow easy access to the COM frequency for background ATC). I only wish
that the flaps sound could be removed, it does not sound right with a
helicopter 'collective' control.....

Just a note regarding 'bleedthrough'. Unfortunately, I have found Flight
Shop a very frustrating program to use on a project like this. If you
require a relatively 'clean' simple aircraft model, it is ideal. Once you
try to add a lot of detail, like I have, the program becomes very 'iffy'
on it's visual output. I bet that 'Master' of Flight Shop, Russ Mueller,
has no problems. But I did. Hope the remaining occasional bleedthrough 
does not affect your enjoyment. Unfortunately, due to these bleedthrough 
problems I had to discard the upper side exhausts. The results were just 
too poor to include in the final model.

At one stage I ended up with no less than 24 glue components around the 
aircraft (those experienced Flight Shop users will know what I mean), and
it became very haphazard, to say the least. The appearance varied so much
between compiled results that it became a hit & miss affair. So I've 
included the minimum glue, and the final result is a compromise between 
a lot of 'bleedthrough' and a lot of visual accessories, and less 
bleedthrough with few accessories. I think that I've got about the best 
I can do with all that onboard detail, like aerials etc. Anyway, I have 
included the AFX for anyone to have a go at any improvements. 

Sorry about the occasional air intake 'bleed' from the forward view, but 
I spent some 80 to 100 hours on a full rebuild, just to erase that one 
problem. Every time I thought that I had it cured, another problem 
arose. So if any of you succeed where I failed, please let me know !  

Incidentally, I did get as far as a 12 sided fuselage, to give a better
silhouette from the fore & aft views, but the visibility problems became
too much of an effort to put right. A lot of the upper engine housings
became invisible, and a lot of detail seemed to disappear at will. So I 
used those extra parts within the 540 parts limit to improve the detail. 
The parts 'total' is currently 522 out of a maximum of 540.

Copyright biz 

An awful lot of my time and effort went into this model. I have no 
objection to anyone who wishes to use any of my work in their own 
creations. All I ask for, is a mention. Give me some credit, if you do.
This is FREEWARE. 

I am including the AFX file here also...since Martin and John, above, were 
gracious enough to include theirs (I learned a lot from their files) I have 
decided to include mine. I would like all of you who benefit from this AFX 
to mention it in your releases...it may encourage more authors to include 
their own AFX files in the future. There is a lot of creative talent 
around...it would benefit everybody, and create much more choice. The AFX
is also intended for those static aircraft programmers. I'd like a static copy, 
if you do one.


I hope this offering gives you as much pleasure as it has given me.
I can now give something back to all those guys who have provided 
me with so MUCH pleasure. Sincere thanks ! AND I mean it.

Keep 'em flying, all !
