FS2004/FSX Yak-9U fighter
=========================
You get a Russian and Korean version.

Plane facts ;
--------------
The Yak-9U was the second generation of Yak-9s. It started with the Yak-911 prototype of late 1943, which introduced a redesigned airframe , a new wing of increased span and area, and the more powerful VK-107 engine.The type had been tested by 28 december, 1943. Early test flights in 1943 indicated that the only comparable Soviet fighter was the Polikarpov I-185 prototype which was more difficult to fly and less agile due to higher weight.
Official State evaluation had been successfully completed by 20 April 1944 by test pilot A. Proshakov.
A total of 3921 Yak-9U(VK-107) was delivered from April 1944 to August 1945. However the aircraft was quite temperamental in the context of engine temperature. From December 1944,new type coolers were introduced. Oil and water cooler intakes sectionals were increased too. Thus the aircraft met requirements and it could reach a speed of 575 km/h at sea level and 672 km/h at 5000 m.
The definitive Yak-9 variant, Yak-9U (VK-105) was equipped with the new Klimov VK-107A engine with 1,230 kW (1,650 hp), and the 20 mm ShVAK cannon with 120 rounds of ammunition replacing the VYa cannon. Weight of fire: 2.72 kg (5.98 lb) /sec. To overcome resulting centre of gravity problems the wing was moved slightly forward . The new type's top speed of 700 km/h (435 mph) at 5,600 m (18,370 ft) was faster than any production fighter aircraft in the world at the time. Early problems with overheating were fixed by enlarging the radiators and production aircraft had further improved aerodynamics. It's turning radius was 360° in 20 sec. it was the best Soviet fighter at altitude.
The Yak-9UV and Yak-9P were postwar versions. The former didn't see serial production, but the Yak-9P was delivered to the Air Force. Furthermore it took part in the Korean War. Production of the Yak-9 ended in 1946 after a record 16,769 aircraft had been delivered.
Main post-war operators, apart from the Soviet Union, were Bulgaria, Poland and Yugoslavia.

Installation:
==============

-Unzip "Yak-9U" into a temporary file and move the "Yak-9U" folder into the main Aircraft directory.
-Attention...the panel.cfg files are different for FSX and FS2004.
-For FSX,change the FSXpanel.cfg into panel.cfg and let it replace the first one.
For FS2004,change the FS9panel.cfg into panel.cfg and let it replace the first one.

-Read instructions carefully when installing the P51d.gau (you find it in the Yak-9U\gauges map), 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 "Yak" map in your panel folder.
-Put the P51d.gau into your Microsoft Games\Flight Simulator X\gauges folder.
-Copy the effects into the Microsoft Games\Flight Simulator X\effects folder.
-Copy the 20can.wav into the Microsoft Games\Flight Simulator X\sounds folder.

Flying the model
================
This plane is a fast, non critical and a good aerobatic flying machine.
In FS2004 tail view is triggered from the 2Dcockpit by the rear view key. In FSX you get it automaticaly when changing views.
-CTRL+E opens the canopy
-Radiator flaps are opened by the close cowl key.
-WEP power boost to 52+ manifold pressure

TAKE-OFF :if you have manual rudder enabled, apply right 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 110 Knots, let speed build up, as the plane at first sinks back to the ground, wheels and flaps up at 130 Knots.
5.Approach at 25% flaps, wheels down at 120 Knots.
6.Touchdown at 70-80 Knots.
