Type History :
==============
With the 21 the classification of Spitfire marks swapped from Roman to Arabic numerals. The wing of the Spitfire had changed very little during the aircraft`s development. However, with the Mk 21 the elliptical wing gave way to a new one with blunted tips and changes to the flaps and ailerons. The wing was made even stronger and carried four 20mm cannon. The fuselage was redesigned and the whole airframe was heavier than previous Spitfires, meaning the undercarriage had to be made more robust. The wheels were now fully covered by undercarriage doors in flight (this had been a feature of Mitchell`s first prototype Spitfire and the prototype Mk III but was not adopted on any production Spitfire before the 21). The usual engine was a Griffon 61 or 64 with a five bladed prop, although a few were fitted with the Griffon 85 with six blades in two sets of three rotating in different directions (known as a contra-rotating propeller) to use fully the 2,375 hp of the Griffon. The Mk 21 kept the normal bulged cockpit. When first introduced the Mk 21 had bad control characteristics, these were cured by modifications to rudder and elevators. 122 were produced.
Effects
--------
-On startup there is automatic engine smoke.
-Then follow the exhaust flames with smoke.
-Wing vortex effect appears by default at 2.5g or quick roll rate.
-Continuous blue flames with smoke if engine is running .
-War Emergency Power is controlled by the WEP.gau (Tick + or 0)
-Wing cannon 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/FSX 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 " Spit21" into a temporary file and move the "Spit21" folder into the main Aircraft directory.
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
-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 !
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
-Leave the fighters.cab in your panel folder.
-Paste the WEP.gau into your flightsim\gauges folder.
-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
-For FSX change the FSX_Wing_Guns.fx into FX_Wing_Guns
If having trouble with the cockpit transparencies in FSX acceleration, copy the glass.bmp and 5bladeprop. bmp files from the Acceleration.texture into the Spit 21 texture folder.
Flying the model
================
This plane is a fair, non critical but very powerful flying machine.
-Spoiler opens cockpit door
-CTRL+E opens the canopy
-Radiator flaps are opened by the close cowl key.
-War Emergency Power is controlled by the WEP.gau
TAKE-OFF :if you have manual rudder enabled, be ready to apply hard rudder and brake when you hit the throttle !
Better apply throttle proportionaly and slowly at first.
1.Parking brake on, start engine, 1/4 flaps.
2.Disengage parking brake.
3.Hold enough rudder, brake to keep the aircraft straight
4.Take off at about 100 Knots, wheels and flaps up at 130 Knots.
5.To fire guns activate O-key or trigger.
6.Approach at 25% flaps, wheels down at 120 Knots.
7.Touchdown at 85-90 Knots.
Like with the real plane, much use of elevator trim will be needed.
