*All air speeds are IAS (Indicated Air Speed)
*All speeds and climb times are on AEC with the obvious exception of “MEC Settings” section
*Speeds are recorded after AEC radiators fully settle/stabilize to ensure accuracy/consistency both at 100% and WEP.
*Map used is Berlin (15.1 Celsius) for all speed, climb and performance measurements. Smolensk and Sicily are only used to adjust cooling settings once cooling settings are found the plane performance is measured on Berlin to minimize variables.
AEC: Auto Engine Control
MEC: Manual Engine Control
0Rad: MEC setting to Fully closed radiator (fastest plane can go with 0 radiator Drag)
Max Speed Alert: When red warning alert appears on speedometer.
Control Lock Speed: Where elevator/controls start to lock up.
Min Ideal Turn Speed: Minimum Speed in a flat turn without contrails (no flaps)
Min Stall Speed: The slowest a plane can travel without stalling (no flaps)
Max Temp Oil/Eng: Max temperature oil/ engine can get before turning yellow
Climb Speed: The airspeed that the climb tests were done at.
Max Kph: Shows 100% throttle max speed in level flight at given altitude
Time w/WEP: Shows climb to 1000M with WEP followed by top speed in level flight with AEC
Hp drop: The altitude where a steep drop off in horsepower begins
Notes: Notes are any extra info that applies with the following abbreviations:
(H): Aircraft runs hot
(FS): Aircraft has fuel starvation
(DC): Aircraft has Drogue Chute
(AB): Aircraft has airbrake
Eng Mix: Engine mixture setting %. “-” in chart, means to leave mixture at default setting. If there is a different value, it will be clearly stated as a percentage. (This affects very few aircraft)
Prop Pitch: Prop pitch setting %. Prop pitch will be shown in short hand “Prop100” = (prop pitch 100%) Prop Pitch can also have a color-coded prop pitch setting according to map temperature. Use Color coded Air RB Map Temperature guide to ensure proper settings
Rad Setting Oil/ ENG: Radiator settings will be shown in short hand “Rad100/50” = (Radiator100%oil/50%water). Radiator settings are shown Cold/Moderate/HOT climate. they are color coded accordingly blue/green/Red. Use Color coded Air RB Map Temperature guide to ensure proper settings.
Super Charger 100/WEP: Elevation to shift super gears 100%/WEP while traveling at indicated airspeed. Almost all chart gear shifts are set at 280kph in the chart. Gear shifts dont need to be precise more than within 100M, shifting up too soon is generally worse than shifting up late.
*For some planes like early Spitfires Prop Pitch adjustments are included under Super charger Column . Super Charger gear shift altitudes listed are for the prop pitch listed in the chart. Example: prop pitch adjustments to 100% at 6000M will look like “P100@6000” under super charger column.
MEC/0Rad WEP Top Speed: Shows top speed Using WEP @ 1000M for MEC and 0Rad (0/0 Radiator) This is used to show how much drag effect the radiator has comparatively.
*Yak Tree in general:
*For all prop driven Yaks, If using AEC Cutting throttle to 96.4 on any map keeps engine cool and out of yellow. This is not an ideal option but if going to use AEC this is better than 100% throttle since it will destroy the engine rather quickly. Cutting throttle to keep engine cool had worst overall performance compared to MEC settings, significantly affecting climb rate by adding about 2-3 seconds per 1000M climb times.
– Yak-1B, 7B, 9, 9B, 9T, 9K, 3, 3P: These planes benefit from MEC over AEC with better cooling. AEC radiators are incorrectly set to 111/111 Celcius instead of 109/109 Celcius causing the planes to overheat. Keeping Prop pitch at 100 preserves climb rate/acceleration but slightly lower top speed. Lowering prop pitch to 90 gives significant heat reduction, speed boost but generally adds about 1.2 seconds per 1000m to climb times.
Both options are outline for each plane to give best of both settings. Settings have been simplified as to not have to remember multiple settings. Use prop100 setting for better acceleration, use Prop90 setting for better speed. Prop90 settings are half the radiator of the Prop100 radiator settings are, reducing the need to remember multiple radiator settings.
*Lowering prop pitch to 90 gives significant heat reduction, speed boost but generally adds about 1.2 seconds per 1000m to climb times for aircraft listed above. Details below:

– Yak-9U, Yak-9P, Yak-9UT: These planes benefit from MEC over AEC overall. These planes run notably hotter than other. AEC radiators are incorrectly set to 111/111 instead of 109/109 causing the planes to overheat. AEC mismanages the radiator where WEP does little or actually makes performance worse. Prop90 has about the same climb rate as prop100 with better speed while keeping the engine much cooler. Prop90 can be used to 4500M, then Prop100 should be used. MEC settings allow for prolonged WEP use. Keep speed above 300-330kph to prevent overheating. Engine hp drop around 4900M.
Details:
*Adding 4/4% to chart radiator can help with extra cooling at -2/-2WEP kph.
*Adding more than 8/8% to chart radiator settings is generally not necessary for cooling.
*MEC settings allow for prolonged WEP use, whereas AEC turns instantly orange.
*Setting radiator to Rad100/100 with WEP had worse climb than not using WEP at all with chart settings.
*Yak-9U runs slightly hotter than other two versions and radiator is adjusted accordingly
*For reference only Prop100 Supercharger gear shifts:
3000/2600
– Yak-3U: This plane benefits from MEC over AEC overall. Top speed increase of over 20kph. AEC has chaotic radiator behavior. This plane gets significantly hotter the lower it goes and the faster it goes. Under 2600M the plane will start to heat up quickly. It is an option to use Prop90 under 2600M for much better cooling and better top speed (+2/+3 kph) at the cost of adding +2/+2 seconds per 1000M of climb. Prop90 can be used to 2600M, then Prop100 should be used. Engine hp drop around 4900M.
*Radiator can be completely closed above 3000M and stay cool.

– I-16 type 27: You can set this to Rad -/100 at all times since there is no perceivable drag produced from radiator. Lowering prop pitch does not help performance, leaving at Prop100 is recommended. Climb is done at 280kph but due to the high amount of drag of this aircraft a lower speed to climb at is suggested, even 270kph has significant better results in climb times. Engine hp drop around 4200M.
– I-185 (M-82), (M-71): These planes run notably hotter than others and prop pitch was lowered to Prop90, making heat manageable at the cost of, approx, 3 seconds added to every 1000M climb. You can still set to Prop100 on initial climb with Rad100/100 for max climb rate and then adjust to Prop90 with Base Rad setting for rest of game to get best of both worlds. The engines on these get hotter as you go higher/faster with temperatures peaking at between 5500-5700M. Generally, set and forget the MEC settings for these planes except for where stated at high alt.

– I-225: This plane benefits from MEC over AEC overall. Rad settings are generally set and forget. Lowering to Prop90 has a significant cooling effect for extended WEP use but offers little to no speed increase (-2/+0 Kph). Climb rate with WEP is almost identical with Prop90 (+2/0) per 1000M added climb time. Prop90 can be used to 8300M, then Prop100 should be used. Engine hp drop around 8900M.
Details:
*Set ½ mixture (Mix30) above 6500m to extend ceiling.
– LaGG-3-66: This plane benefits from MEC over AEC overall. Rad settings are set and forget since airspeed seems to have little to no effect on cooling. This plane has better climb in addition to better speed and cooling with Prop85 setting. super charger gear shift is 1800 regardless of prop pitch setting between Prop80-100. Mix should be lowered by ½ to MIX30 above 6800M to extend ceiling. Engine hp drop around 3100M.
– La-5, La-5F: These planes benefit from MEC ove AEC overall. Prop90 was much cooler, better top speed (La-5: +5/+3 Kph) (La-5F: +5/+5 Kph) and had same climb rate as Prop100. Prop90 can be used to 5800M, then Prop100 should be used. These planes get significantly hotter the lower they go and the faster they go. Under 1700M the plane will start to heat up quickly. Engine hp drop around 5800M.
*Super charger gear shifts and Hp drop are the same for Prop100 and Prop90.
*Radiator can be completely closed above 1700M and stay cool.

– La-5FN, La-7,La-7B-20: These planes get significantly hotter the lower they go and the faster they go. Under 2700M the plane will start to heat up quickly. It is an option to use Prop90 under 2700M for much better cooling and slightly better top speed (La5FN: +2/+4 kph) (La7, 7B-20: +0/+4 kph) at the cost of adding about +2/+2 seconds per 1000M of climb.
