FS2004/FSX Armstrong Whitworth Siskin fighter
=================================
The origination of the Armstrong Whitworth Siskin series of aircraft can be traced back to a post-World War One aircraft design designated as the Siddeley Deasy S.R. Siskin. Initially composed mainly of wood (common for aircraft in the First World War), the plane had to be redesigned at the request of the UK Air Ministry, fulfilling their new requirements for an"all-metal" aircraft.
By comparison with the Siskin III, the Siskin IIIA introduced a number of major design changes, including a lengthened fuselage with raised aft decking, greater gap and less upper wing dihedral, and redesigned vertical tail surfaces lacking the ventral fin. Retaining the twin 7.7mm Vickers gun armament, the Siskin IIIA was powered by the 425hp Jaguar IV or super- charged Jaguar IVS engine, and the slab-sided fuselage gave place to a fuselage with more rounded sides. The Siskin IIIA, to Specification 19/23, first flew on 20 October 1925, and was ordered for the RAF in June 1926, 412 being built, including 47 dual-control trainers, 17 of the single-seaters being supplied to the RCAF. Of the total production, the parent company built 159 (Blackburn building 42, Bristol 85, Gloster 74 and Vickers 52). At least one was completed as the experimental Siskin IIIB with an uprated engine enclosed by a Townend ring.
The redesigned Siskin III entered operational service in 1924, becoming the Royal Air Forces first all-metal purpose fighter in history.

Impressively, the Siskin series soldiered on throughout the 1930's, being retired from RAF use in 1932 and staying in service with Canadian forces as late as 1939. Siskins later would begin developing a tradition for acrobatic flying capabilities leading up to some famous traveling circuses. With just over 450 Siskins produced during the production run, some were exported to Estonia as well as Canada.

Effects
--------
-On startup there is automatic engine smoke.
-Then follow the exhaust flames with smoke.
-Continuous blue flames with smoke if engine is running .
-Guns with flash, smoke and falling cartridges can be triggered with the standard Strobe key (O).
It is much nicer however if you put the FS2004 standard Strobe key (O) to the trigger from your joystick.You can change this in the Key menu.
It is a good idea if you replace the standard (L) key for lights by the L+CTRL, (normaly activating the landing lights only). This avoids you having to have all lights on when pulling the trigger.

Installation:
==============
-Unzip " Siskin" into a temporary file and move the "Siskin" folder into the main Aircraft directory.
-With slight mods the plane flies in FS2002 and CFS2 (Use MDLC program and change gauges)
-Leave the PW-9.cab in your panelfolder.
-For FSX change the FSXpanel.cfg into panel.cfg.
-For fs9 change the FS9panel.cfg into panel.cfg.

-Read instructions carefully when installing the gauges , say YES...when asked if the gauges sources should be trusted. If you say no....most of the gauges are not going to work !

-Copy the effects into the Microsoft Games\Flight Simulator X\effects folder.
-Add the 20can.wav in your Microsoft Games\Flight Simulator X\sound folder.
ATTENTION :
-For FS2004, change the FS9_Wing_Guns.fx into fx_Wing_Guns.fx
-For FSX change the FSX_Wing_Guns.fx into fx_Wing_Guns.fx

-Sound has been aliased to Douglas_DC3 and can be modified at wish.

Flying the plane:
=================
Remember...this is an early fighter biplane! Manoeuvrability is good, but the plane has to be flown with care and good coordination between aileron/rudder and elevator. It rolls fine with aileron/rudder combination and is responsive to elevator. Nice flying aerobatics close to the tower !
Go to about 130 knots for a loop. On top of it, you'll be very close to the stall. When stalling you're going to enter a corkscrew. To get out of it, use reverse rudder, full power and dive the plane. Wing over, knife edge, segment rolls are all possible.
- Hold up elevator to start the engine, you have no brakes and the tailskid must firmly be on the ground to stop the plane.
- Take off at about 60, correct with right rudder
- Climb at 70, level at altitude, speed slowly builds up to 125 kts.
- Landing approach at 80, over the fence at 65, touchdown at 60. You need some up trim for a threepointer.
- Hold up elevator for the tailskid to brake the plane when taxying.
