In this video, I present a very advanced and dangerous MEC trick that you can use to mitigate the thrust loss at low speed that Bf109s, especially high tier Bf109s, suffer from. Included are the thrust graphs at various prop pitch % and of course the reference thrust as a function of speed with automatic engine controls.
This trick is mostly useful in duels, and in a pinch like in this video:

[@DRUBZTheBlazeOfArt]

This explains why I can't stall climb without breaking my engine in a spitfire in DCS, very useful knowledge.

[@AdamTheEnginerd]

Oh really?

[@DRUBZTheBlazeOfArt]

@@AdamTheEnginerd Everything engine control related is manual in DCS, and in order to stall climb you need to push the engine quite a lot. Either that, or something to do with how the spitfire uses a carburetor? The engine fails if you perform a prolonged stall climb, an excessive dive, or a flat-spin. (And engine shut-off due to fuel flow if upside-down or pulling negative g's)

[@AdamTheEnginerd]

Maybe you were in neg Gs for a few too many seconds in that climb and your engine shuts off.

[@DRUBZTheBlazeOfArt]

@@AdamTheEnginerd Nah, the engine breaking and the fuel shutoff are two different things. Pull a standard stall climb, come out of the stall climb, and the engine is banged up and smoking - however still running the entire time. A fuel cutoff then can just do a mid-air engine restart and no loss of power.

Another useful tip, if you are being chased and want to make the enemy overshoot, throttle all the way down to 0% and leave prop pitch at 100% the effects are so extreme that even your player camera shoots forward

[@AdamTheEnginerd]

Yup, that's another trick in my playlist, the prop pitch airbrake.

[@ikazuchi-san5772]

yea he called it the german airbrake

[@davecrupel2817]

As an aircraft mechanic, i am proud of you for figuring out prop pitch, and how you can use that to your advantage in-game. 95% of all prop airplanes' propellers can have their pitch adjusted. They can go from a *full feather,* (which is when the blade is perpendicular to the direction of movement) to a full 90° "flat" position. Turboprop propellers can even go all the way into reverse. They slow down on landing this way. Now on most planes, this is a more or less automatic process, for the most efficient operation. The pitch is reduced as your throttle and RPM increases, and increased as you lower your power & RPM. The only control you have is adjusting the upper and lower limits of that, using an RPM lever type control in the cockpit. On a piston aircraft, you have three such controls. Throttle, mixture, and RPM. On a turboprop, you only have two: power and RPM. When you shut your plane down, the best practice is to bring your RPM all the way either up or down. It covers the pitch changing mechanism, and protects it from the outside world. On a turboprop, it's much more important to do this because it also prevents your propeller and engine from pinwheeling in the wind. This prevents an unlubricated engine from turning, and wearing excessively. Hope you enjoyed this bit of knowledge. *Would you like to know more?*

Thanks! Hmm I would say they have roughly similar thrust at low speed. Reason is the same as in the video, the P51H's power is too high for its propeller, so there's a loss in efficiency there that the D30 doesn't have because of its lower power.

​@@AdamTheEnginerd I can actually tell you the exact moment LOL 2:19 How can prop angle/pitch be a function of speed when the two are completely independent? Also maybe this is why I couldn't really figure out how to effectively use MEC anyway, but why are the angles so low? I thought 100 was generally the best unless you're diving or at cruising speed (where you'd drop your pitch to reduce your propeller decelerating you from drag)

[@carl-magnuscarlsson7713]

@@icetheking4310 note that the grey line in the graph is just the settings by the AUTOMATIC prop pitch controls.

[@AdamTheEnginerd]

@@icetheking4310 Pitch angle changes with speed because if the prop had a fixed pitch, it would get easier and easier to spin the prop as the aircraft accelerates because the propeller will be seeing a lower angle of attack or a smaller "bite" of air as the aircraft goes faster. Props in WW2 were constant speed propellers, so the pitch angle of the propeller would change with speed to keep RPM constant and to stay close to the more efficient angle of attack for the propeller. What angles are low? I think the confusion stems from the fact that you don't know that German prop pitch works differently than for every other nation. For the Germans, prop pitch % will give a pitch angle directly, while for other aircraft, prop pitch % gives the target RPM instead. It's also why this trick would only work on German aircraft. Except for German aircraft, the general rule is prop pitch = throttle.

[@icetheking4310]

[@ferrarisuper]

Great video as always! I learned this trick from you 1 year ago and it’s extremely important to fight 1v1s against aircrafts that can match 109s climb rate like the Griffon spits or the yak3. Since you can’t outturn them, the only way to get behind them is to reverse the situation with a stall climb. After the headon climb at medium speed (about 330km/h IAS) then when they are like 2 km away from you go full vertical and use the trick. If they followed you in your medium speed climb, they are dead. Some players might start climbing at more efficient speeds without committing, then just run away and focus on others, since if they don’t commit, they aren’t a threat to you.

[@AdamTheEnginerd]

Thanks! Getting slow against a Griffon is likely a death sentence. Using it against Yak3VK can be viable.

[@ferrarisuper]

AdamTheEnginerd at medium high altitude is the best was to kill the LF or the VK. Against griffon it works between 4000 a and 5000 meters. At high altitude (6000m) I usually start running away until i get about 3 km distance, then stall climb, and then you’ll be again facing each other at about 1.5 km, but you’ll have a small energy advantage. Just repeat this trick 1-2 times more and you’ll have a big energy advantage. If, instead of following you running, they start climbing just ignore them and go for other enemies. Obviously with a decent team bait and switch is a much much better tactic much less dangerous

[@Acid_Burn9]

Thanks for the vid, Adam, it's really useful! Now i don't have to do shit-ton of test-flying myself to figure out the optimal pitch for 109s. Looking forward for more content! :)

[@AdamTheEnginerd]

Thanks for watching!

[@StarWarsMasters]

I have an extremely important note for the 100 prop pitch in a 109. If you dive then enable the prop pitch at like 5 to 6 hundred kmph IAS, it will slow you down to 0IAS so don't forget to turn it back to auto before you lose all of your speed and stall. I recommend turning it on when you are at the beginning of your dive near 300kmph IAS since it lets you gain speed, but not as quick.

[@AdamTheEnginerd]

Yup, prop pitch airbrake is another trick.

[@StarWarsMasters]

@@AdamTheEnginerd Yea thats what I'm talking about. Enabling it at high speeds will make your speed go backwards, but enabling it before you dive lets you gain speed slowly.

[@shrekrecker]

the difference in some planes turn rate on mouse aim and "realistic" control is astonishing, as a suggestion i would look into it more, great video adam

[@shrekrecker]

its not just turn rate, i would say it completely changes the plane (on some planes)

[@AdamTheEnginerd]

Hmm I remain skeptical. You need testing to make sure it's not just your impression due to pulling more AoA, and the higher speed loss will worsen your turn time.

[@shrekrecker]

@@AdamTheEnginerd one more question, i dont know if its a warthunder flight model thing or if its a realistic mechanic, but when you pitch up hard on a horizontal turn, the plane suddenly losses control after a second or 2 and starts aggressively rolling.

[@shrekrecker]

oh and roll rates are definitely slower, i dont even know if its possible to do mouse aim rolls with realistic controls

[@AdamTheEnginerd]

@@shrekrecker Well that's because you're beyond the stall angle, hard to control an aircraft past its stall angle.

[@novaschin7946]

If this happens because of the small propeller then the Tempest and the F8F are good because their propellers are huge(or they look huge at least)

[@AdamTheEnginerd]

Yes but remember it's the ratio between power and diameter that matters as well, and they have more power than Bf109s. Indeed they do handle low speed better than Bf109s. F4U4B handles low speed very well.

Flying F7F-3 the 20mm is working like a charm Flying the FW-190C MG-151 working like a charm Flying the and the I-225 with the same or double amount of Cannons they do litraly nothing but sparking... sure after spamming 50-80 bullets in to the enemy plane he maybe will die (counting that not every shot will hit but to get the same result as the F7F for example i need not even half the amount of bullets fired) Flying the Spitfires the 7.7s seem to do more than the Hispanos Flying the Japanese aircraft wich resemble gambling since out of 100 games i can not get something evidential out of them Didnt touch China Gertaly usses the MG151 so... works The Hispano 404 on the Frenchies are somewhat of an middle thing to the AN/M3 and the Hispano Mk.2/5s they seem to do more then British ones but less then the americans... even they are more or less the same Cannon, besides the ammo loading and reliability they are not that much different in real life. The Swedish boys... my god they are Brain dead to use... one of those and the enemy goes boom even their 13.2mm are Broken This is just for 20mm Cannons... wich is basicly the biggest problem here... but now moving up to the High battlerating stuff... MiG-15/bis/17 i used to one tap my mouse hit an enemy and the enemy would go boom now i am used to one tap my mouse the enemy gets Hit and i get sparks/ and Hits out of it... Same with the german MK108s while the MG-151 and MK-103s are doing fine.... and lets not start with the MiG-21SMT 23mm cannon... that thing is a spark launcher... i mean a friend of mine called it out that the 23mm Gsh on the 21 is going to be as shit as on the helicopters or on the Il28Ish. But the 30mm on the F-13 is still doing fine... like i end up getting 3 kills on the SMT with 2 on R60s and 1 on the cannons but by then i used all of my ammo... while i get an ACE on the F-13 while still having 20rounds left... Now here is my point... why is this happening ? I tried nearly every single belt nearly every single cannon and the results wont change... I looked up on the Forums, and there is Latency on one point the others say gaijin cant code, while others say there is no real problem cuz 50.cals work fine then again other people say they hafe no problem... and i need answers because this is getting me mad and frustrated since so many cool planes are unplayble because their amarment just doesnt work....

[@SgfGustafsson]

In the beginning you're talking about a Vx climb, once you add the constant speed propellers in its getting into propeller efficiency. I don't play war thunder so idk how the game's planes work, but normally you set the propeller governor to a certain engine rpm that is most efficient for a specific power setting. Like in a Piper Arrow II, a good climb setting is 25" of manifold pressure and 2,500rpm on the governor. Edit since I read my own comment: Both things I was talking about are about propeller efficiency lol

[@AdamTheEnginerd]

The automatic system in most planes takes care of changing RPM when you change throttle. In this plane you actually need to manually override the automatic system to give the pitch and hence RPM you want.

[@SgfGustafsson]

@@AdamTheEnginerd ah ok, in 'real life' you control the pitch of the propeller by setting the spring tension on a governor via a lever, which adjusts it to seek an engine rpm by either increasing or decreasing the pitch angle of the blades to add or remove torque/load from the engine. So, set the rpm with the propeller control and it will hold that rpm regardless of power setting. I'm sure newer aircraft with special computers constantly adjust this automatically like on the new Technam. Thanks for the clarification!

[@petrkdn8224]

Spitfire LF at 5.7 has 32m/s spaded climbrate. With 100% Prop. pitch it has around 40m/s and is an absolute beast, and starts overheating until like 6-7km (also the supercharger has 2 gears which let you have around 40m/s climbrate up to around 3-4km and then around 4-7km you have 30m/s)

[@dogeness]

I think I finally understand this effect now. I wasn’t getting it before because I wasn’t taking into account that thrust increases as speed decreases. That’s why the engine overrevs below a certain speed, isn’t it?

[@AdamTheEnginerd]

Hmm the prop stalls below a certain speed, so you want to increase RPM to decrease AoA and hence increase prop efficiency.

[@dogeness]

@@AdamTheEnginerd I understand that the prop is stalling below 200kph which is why you manually increase RPM to prevent that stalling. But what I don’t get is why the prop pitch starts increasing below 200kph in the first place (btw I’m using the term prop pitch in the traditional sense, not the % like in wt) Dynamic pressure acts to increase the RPM of a prop, doesn’t it? So how is it that the lack of dynamic pressure below 200kph causes the the prop to over-rev (thus making the game increase prop pitch to prevent the over-revving)? Shouldn’t the lack of dynamic pressure mean the prop revs less?

[@AdamTheEnginerd]

Dynamic pressure is what provides the torque on the prop, if you reduce that you'll increase the revs if pitch angle remains constant.

[@dogeness]

@@AdamTheEnginerd Yeah so that statement by itself makes sense, but I'm having trouble reconciling that with the idea that, for a constant prop pitch, RPM increases with airspeed. If dynamic pressure is increasing, why do fixed pitch props spin faster when the plane speed sup?

[@AdamTheEnginerd]

@@dogeness For constant pitch props, the RPM increases with speed because it reduces the AoA of the prop and hence less torque on the prop, so RPM increases. In the K4's case here, the usual happens where the prop pitch reduces as speed reduces until a bit above 200km/h. Below that speed, it looks like the reduction in dynamic pressure "is too significant" for the prop to handle causing a tendency for the engine to overrev, so the prop pitch governor increases prop pitch instead to create more torque to prevent overreving.

[@Lord.Kiltridge]

I only want to be able to throw the prop pitch into reverse thrust. It needs to toggle from automatic to full reverse pitch and back to automatic. I would bind it to the same key that I have my airbrakes and thrust reverser on. I already added a separate key so I can apply wheel brakes while I maintain full throttle and tested it fully with my SK60B. With it I can come in at full WEP, hit H, deploying airbrakes _and_ reverse thrusters, and hold the B for wheel brakes as well. If I can toggle reverse prop pitch on and off with my airbrakes, (where applicable), I can get the same effect across a wider selection of aircraft. How can I set up my prop pitch to toggle as described?

[@thermite10k40]

hey Adam! thx for the vid. i watched your first video about this trick 3 years ago and use it any time i can. the main thing is using it during the heat of the battle.at the start of the match i put my pitch at 68% but active auto pitch after that. once i need it i switch to manual pitch and it goes to 68%. good thing about 68% is it can be used below 2500m easily. BTW the new mustang is a joy to fly. based on my tests put the pitch at 90% and radiators at 55 for hot maps and 45 for cold maps to prevent significant emotional event during climbing. can i use this trick on ta152? i looks like it has a small prop compared to it's engine power .

[@AdamTheEnginerd]

My pleasure! Yup you can get the pitch ready so that all you need to do is activate manual prop pitch for it to work! You should use it on takeoff, you takeoff a lot faster. Ta152 actually has a significantly bigger propeller than Bf109s with not that much more power, it doesn't have to use this trick.

[@Parathong]

Great video, thanks you very much! Can I ask you something since I'm new to this? I use pitch control 70% to climb in the start of a match. Can I keep this value of 70 during battle and just switch to auto pitch control? Or is it better to reset pitch to 50% first and then switch to auto? During battle I'll use WEP and I'm not sure if 70% with WEP will hurt the engine or affect performance.

[@AdamTheEnginerd]

I definitely recommend keeping prop pitch on automatic, except if you want to use the prop pitch airbrake trick. There's also the extra thrust trick, but that can come later.

[@AdamTheEnginerd]

Watch my MEC video for more details, but usually you can keep at 60% since it isn't modeled on most aircraft.

[@lukefrombk]

Hey Adam very interesting thing you said about propellors, check for yourself in game. The G14AS has wider diameter propellor blades than any other 109. This trick would probably work extra well with it then. I have alot to say so I'm gonna condense everything into one comment to not spawn the comments section. So the wider the diameter of the propellor the more it can convert engine power into propellor efficiency at low speeds? From your G14 AS video I remember you recommended not using WEP in 109s in low speed vertical stalls, does it say mean if not using MEC but just reducing throttle and automatically pitch, you would still get better propellor efficiency in vertical stall?

[@AdamTheEnginerd]

So it also has a bigger landing gear? Because the diameter can't increase much without running the risk of hitting the prop on the ground. If it does indeed have a bigger diameter, then it would need this trick less than other Bf109s. I think it was in my G2 video saying I'm laying off WEP at low speed to cool down since it doesn't affect thrust much. You get better prop efficiency by reducing throttle, but then you have less power to convert into thrust so you still lose on thrust.

[@lukefrombk]

@@AdamTheEnginerd I see I see, I understand. Thanks for the reply Adam : ) on what you said about the landing gear I'm not sure but from I could compare in game, the tail section and starting from some of the rearward pillars is different than the German 109s. The rear section is bigger than the G2 Trop and G6 but smaller than the G10/14 and K4.

[@lukefrombk]

@@AdamTheEnginerd Could a differently sized rear section and tail compensate for the size of propellor increase, how a larger landing gear would?

[@AdamTheEnginerd]

@@lukefrombk Nope, since what matters is the clearance you have between the propeller and the ground when the aircraft is horizontal (about to takeoff or right after landing).

[@lukefrombk]

@@AdamTheEnginerd Oh! I understand, I was way off, thanks for explaining it!

[@daniel_f4050]

A little late to the party, but.... Is there a point when torque overwhelms control authority as IAS reduces? Does Gaijin not model that as it could cause too many ground loops thanks to the Me 109’s infamous narrow track landing gear? Or is not really a problem as long as you are paying careful attention to the throttle and propeller pitch angle?

[@AdamTheEnginerd]

There's no torque in RB, but in SB there definitely is, you can't aim well if you're below stall speed in SB.

[@appa609]

What happens if you progressively reduce throttle below 200 km/h to keep the automatic pitch control from stalling the prop? If overevving is the main limit then maybe you'll get even more thrust at very low speed with 100% throttle and 80% pitch than WEP throttle and 70% pitch, or something like that.

[@AdamTheEnginerd]

That is a good observation. On some aircraft that works (P51H) because WEP and 100% have the same RPM. However, on the K4 for example, WEP RPM is 2800, but it goes down to 2600 RPM at 100% with a loss of around 600 HP, and that's 600 HP that you can't convert into thrust even if you improve the prop efficiency at low speed, so you're still better off WEPing.
