-Fiat G-50 "​Freccia"​ ("​Arrow"​) +[[Fiat G-50|Fiat G-50]]
- +
-The Fiat G-50 was one of the game's most difficult aircraft to modify to correct specifications. The CoD engine has designated that it shares the engine of the BR-20M, while in fact they were equipped with different types, the G-50 had the Fiat A-74/38 and the BR20M had the A-80. One was a 14 cylinder Radial, the other was an 18 cylinder. Both had different boost levels and maximum rpms. +
- +
-The new modified version of the G-50's A74/38 engine has been modified to reflect its correct historical boost and rpm limits. +
- +
-The Lift Profile of the G-50 has also been modified to reflect its wing-loading and aerofoil design. +
- +
-ENGINE +
-Fiat A-74/38 Radial with Single Stage Supercharger Full Throttle Height of 4100 meters (unrammed) +
-3 minute power setting +
-2520rpm at 890mmHG (WEP) boost at sea level to 3000 meters +
-2520rpm at 790mmHG boost over 3000 meters +
-30 minute Climb setting +
-2400rpm at 700mmHG boost +
-Unlimited Cruise setting +
-2100rpm at 590mmHG boost +
-PROPELLOR +
-Aircraft has a Fiat/​Hamilton constant speed propellor, maximum rpms at 2520.  +
- +
-ENGINE TEMPERATURE MANAGEMENT +
- +
-The aircraft has an air-cooled Radial engine. Air Louvre shutters are opened or closed by the pilot to regulate the temperature of the engine cylinder heads. The cylinder heads can be monitored by a single gauge on the dash, a selector switch on the right of the dash determines which pair of cylinders has its temperature displayed on the gauge. +
- +
-Cylinder Head recommended temperatures:​ +
- +
-Minimum: 140c  +
-Normal: 200-240c  +
-Overheat 260c +
- +
-The engine also has an Oil Radiator. A gauge on the dash displays oil temperature. +
- +
-Oil Radiator recommended temperatures:​ +
- +
-Minimum: 50-60c  +
-Normal: 70-90c  +
-Overheat: 95-100c +
- +
-STARTING THE ENGINE +
-1)  Magneto to "​1+2"​ position +
-2)  Throttle 10% open +
-3)  Engine Air cooling Louvres closed +
-4)  Oil Radiator closed +
-5)  Activate hand pump +
-6)  Start +
- +
-ENGINE WARMUP +
-Engine must be warmed prior to takeoff. ​ Leave Air Louvres and Oil radiator closed till following:​ +
-1)  Using Cylinder Head Selector switch, monitor Cylinder Head Temperature gauge, temperatures must be 140c prior to takeoff +
-2)  Oil Temperature must be 40c prior to takeoff. +
- +
-TAKEOFF +
-1)  Open Cylinder Head Air Louvres to 100% +
-2)  Open Oil Radiator to 50% +
-3)  Lower Flaps to 1st position +
-3)  Select Full Fine Pitch (2520 rpm) +
-4)  Activate WEP power, 890mmHG emergency boost +
-After aircraft is airborne: +
-1)  Raise undercarriage +
-2)  Raise Flaps +
-3)  Reduce power to 700mmHG +
-4)  Reduce rpms to 2400 +
- +
-TRIM +
-The aircraft has full trim for all controls, elevator, ailerons and rudder. +
- +
-PERFORMANCE +
- +
-Max. Speed at Sea Level: 415kph +
- +
-Aircraft has a single stage supercharger,​ with the Full throttle height being approx. 4000 meters. Performance falls off rapidly above this height. Most historical G-50 Squadriglia did not operate much over 4000 meters. +
-The G-50 is capable of quite good level turn performance,​ and a good G-50 pilot can surprise an unwary Spitfire or Hurricane with its maneuverability. But it is a relatively slow aircraft compared to other fighters. +
- +
-CONTINUOUS CLIMB +
-1)  Open Air Louvre full +
-2)  Open Oil Radiator to 75% +
-3)   ​Select 700mmHG boost +
-4)  Select 2400rpm +
- +
-CARBURETOR MIXTURE +
- +
-The engine is equipped with a carburetor which requires mixture settings to be adjusted according to altitude. +
- +
-Recommended Mixture Settings +
- +
-0-2000m: ​ 100% mix +
-2000-4000m: ​ 95% mix +
-4000-6000m: ​ 90% mix +
-6000-8000m: ​ 85% mix +
- +
-DIVING +
- +
-Maximum Dive Speed: ​ 720kph IAS +
-When diving, pilots should partially close their Air Louvres and Oil Radiator to prevent the Cylinder Heads and oil from cooling too much otherwise misfiring and rough running may result. +
- +
-LANDING +
-1)  Set rpms to 2520 +
-2)  Slow aircraft to 230 kph  +
-3)  Select Full down Flaps  +
-4)  Select Undercarriage down +
-5)  Trim aircraft for level +
-5)  Approach speed at 175 kph, reduce to 165 kph over threshold, maintaining throttle. Do not reduce speed below 155kph, fly the aircraft onto the runway.+
