As Art-J said: From the real manual. With revision from 1971. So if that procedure was wrong, surely it would have been changed by that date. Fox

The Sabre´s ailerons are out of square. The stick position in these pictures is neutral. The pictures were taken in SP. I didn´t press "Fly" after loading. Instead I pressed ESC so the controls are neutral and the game is paused. It is best visible at the wingtips. Fox

Hi Mike, It´s in front of you, but you won´t see it unless you go down with you view. Press RCTRL+RShift+Num2 all the way down. It is the "round" knob. Press Num5 to return to you normal view. Fox

Try the FAB-500 M62. With these I can crack modern tanks. Fox

Activating SAU the aircraft stabilizes and flys level. Of course the stick should remain in the last position when SAU is cancelled. Thus no pitch change should occur. Anything else wouldn´t make sense. And how else should SAU control the aircraft? Trim is not performed by trim tabs, but by moving the joystick and thus moving the whole elevator and the ailerons. Fly low level(50m height and altitude below 500m) with SAU activated and full mil power. When you have 1100km/h IAS cancel SAU. And for the double trim bug check the video in this post. Fox

As the double trim problem still persists I made a video to show what seems to be a bug. For comparison the Su-27 trim function is shown at the end. Fox

You´re welcome Mike :thumbup: We had a lot of fun. Thinking about it again it might have been a problem with the sparkplugs, because we were idling very long. No it doesn´t. But I´ll try to reproduce your finding. Fox

WildBill wanted to know how to calculate the performance of the Huey with the help of the performance charts. "Hi again, I'm looking for tutorial on how to calculate the following: 1- torque available 2- hover power required and hover ceiling..." Then I answered him by posting the 30minute torque available chart with my annotations, to provide him a guideline, how he can calculate the performance. I took the values that are given by the flight manual itself as an example. Neither WildBill nor I talked about exceeding limitations. Just performance calculation in general. And then you started with exceeding the limitations. That´s why I said "you asked for it". Well you can see it that way, that I "essentially" confirmed your post, but thats only half the truth. With every small increment of exceeding a limit, you increase the overall failure probability, exponentially. Throwing in your opinion without accepting a discussion won´t help finding the truth. It is realistic that nothing happens, when you exceed the limits by 1% for a blink of a moment. But its completely unrealistic that you can pull the collective all the way up to the mechanical stop and have the EGT around 800°C for a long long time. After one hour, I stopped this test. Nothing happened, no failures. That chart I posted does only tell you the maximum torque the engine is capable to produce under certain environmental conditions. I have the impression that you don´t understand what it means to exceed a mechanical/structural limit. It´s not: Oh I exceeded a limit, now let´s throw the dices to see what might happen. You cannot say that the possibilities have equal probability. This isn´t a lottery. It does never happen anything at all in the DCS Huey. I never had engine chip, mgb chip, main rotor failure or engine failure because of exceeding a limit/limits. Nothing. These torque figures are only examples from the flight manual. They are not from WildBill or me. They are just examples, how one can calculate the torque available. Both the calibrated and the indicated torque. Yes your right, I said that the engine values have "issues". They have issues, because ED/BST set the bar so high with the "realistic modeling of the UH-1H engine". Fox

Yes, this chart can be used to check the DCS Huey, because: "Realistic modelling of the UH-1H instruments, weapons, engine, radios, fuel, electrical, and hydraulic systems." Thats a quote from the DCS homepage. Unlike the comparative/relative "most realistic...experience" for the flight physics, the engine modeling is described as realistic, in absolute terms. So it has to withstand the comparison to the real Huey´s engine. ED and BST themselves set the bar so high. We are totally drifting from what WildBill wanted to know, but you asked for it. Fox

Now that you mentioned it :doh::doh::doh: You´re absolutely right. Have the G940 too. Same behaviour. Additionally when I cancel SAU mode in level flight, depending on the speed the aircraft pitches up, stays level or pitches down. Do you have this aswell? I guess it´s from the double trim bug. Fox

Check your settings for double allocation of the cyclic axes. Fox

Just switch on these systems after connecting the GPU. Then the start up should work. Copied from the russian manual. Fox

Could anyone of the "roll plagued" post a track? Fox

That´s why I don´t want to post anymore in the bugs section. I don´t want to discourage anyone of flying any DCS module. Sorry if I did that. There are bugs, there are problems, there are wrong values, but it is still a enjoyable module. And I still hope to see improvements when DCS 2 gets released. I´d accept and welcome a Huey 2.0 and Mi-8 2.0. Sondo, I think we are somehow victims of our own expectations, maybe fed by marketing. This is not a professional full flight simulator. Even those have their flaws. I was at a point where I didn´t want to fly any helicopter in DCS anymore. But now I just reduced my expectations for a 50$ software. It is still the best Huey simulation for this price for a home PC. You have to ask youself: Do I really expect the feature set and detail depth of a multimillion full flight simulator brought to a home PC for only 50$? Fox

That´s not easy to answer. I don´t have temperature charts for the engine. But from the charts I have and after interpolating forward and back: Std. day-> HOGE @ ~7200ft altitude, +/-0°C OAT, @4200kg, the engine should be just before passing 610°C. Fox

There is always a description in the TM55 preceeding the charts. Read the method. Unfortunately the DCS Huey does have different engine parameters. Especially torque available and EGT don´t fit. Fox

You´re welcome. Unfortunately the values are so far off that it doesn´t make any sense to create triggers for it. For instance: Std day, 15°C, QNH 1013/760/2992, wind 090/6kts Hover OGE, alt 100ft GW: ~4200kg/9200lb leads to an EGT of 680°C !!!!! at these conditions it should be still in the continuous rating. So, it might be a good training to set these triggers. But its a training for you to learn the mission editor and the triggers, but not for the real Huey limitations. Fox

The limit ranges are set to maintain reliable, non-degrading(short-term), non-destructive operation. So exceeding these limits, depending on duration and amount of exceedance, increases the failure-probability of vital parts and reduces their performance permanently or even destroys them instantly. The temperature inside the combustion chamber is too high to be measured. To have an idea of this temperature, the temperature at a point after the combustion chamber, where it is low enough for the temperature probes to not melt and give reliable temperature values, is measured. Roughly 75% of the air which is ingested by the engine is for cooling and separating the flame from the combustion chamber. If the flame gets bigger and bigger because of higher and higher fuel injection rates(increased power demand) or less air is ingested (increased altitude and/or outside air temperature) the isolating airflow gets thinner. Once the isolation is too small the flame starts to melt holes into the combustion chamber. This can go quickly and will change the airflow inside the chamber, but not to the positive side. That can than lead to an accelerated destruction of the chamber walls. Fire spreads in the engine compartment. Aircraft personnel gets nervous.... Prolonged moderately high EGT might not lead to the destruction of the combustion chamber, but will lead to deformation of the blades inside the engine, both the rotating as well as the fixed ones. Which leads to reduced performance/power output. As this turbine has two shafts. This will lead to reduces capabilities, first of the gas producer to ingest air, second of the free turbine to convert the hot gas energy into rotational movement. Now look at the given temperature limits for the engine. Up to 610°C you have continuous operation. That means with additional fuel tanks ~4:15H operation under load! Between 610°C and 625°, so only 1°C to 15°C more, operation is limited to 30 minutes already. There should be some kind of safety margin, but it won´t be too big. So I guess, as I don´t have data for this, increasing the EGT above 630°C the degradation could already start. Further increased EGT would lead to accelerated degradation. This problem is not easy and a simple script just won´t do it. But, as the values for EGT are not correct ->For the time being: Adopt a cross check pattern where you include EGT, but until correct values and limitations are included, it is a value without use. And looking at the other limits: Do you now Cypher from the movie Matrix? The scene where he talks to agent Smith while eating a steak? ->"Ignorance is bliss"<- Right now I don´t want to pull anyone out of the matrix. I´m hoping and waiting for DCS 2. After the release of DCS 2 I might start threads with all my findings. In the meantime I encourage everyone to enjoy what we have now. The flight model is good. Considering the limits that apply for a home computer with short cyclic- and collective sticks, etc, it does really feel good(warning: totally subjective opinion). Fox

Sondo is not talking about better EGT simulation. There is no EGT simulation. You are talking about better possibilities in DCS 2? So does any other DCS aircraft have EGT simulation? Why do their developers make the effort to simulate it now if that wouldn´t make sense? Your assumption would lead to no EGT simulation in any subsequent Belsimtek module that came after the Huey, as "...it makes no sense to pay someone to write an EGT simulation that's going to be depreciated right away." His initial post asking for EGT implementation was from 28 January 2014. Now do the calculation again please. Because people are passionate about DCS aircraft, they discuss these topics. I do hope too that with DCS2 we get some updates. I would gladly pay for a Huey 2.0, as there is unfortunately enough room for improvement. But it is still the best Huey a normal mortal can buy. TO, honestly, EGT is no problem in the Hotel Huey. The indication in the DCS Huey is simply too high. It´s at least 60°C too high. Don´t waste you time trying so simulate problems that don´t exist in the real helicopter. Currently it appers there are no limitations implemented for the engine and transmission. Simply enjoy flying her. Sondo, I totally understand your anger about these things. I thought so too. But it won´t help. I just stick to the known limits and fly as if they were implemented. Fox

Basicly it is similar to the ARU system in the MiG-21Bis. With increased speed, deflection decreases with constant stick position (ignoring altitude for a moment). How do you expect to overcome the discrepancy between the nonexistend forces on the physical joystick vs. the forces that build up on the virtual stick? How do you measure AoA in the Bf109? Are you sure the aircraft´s AoA is constant? Fox

Looks like dust on the camera´s sensor. Fox

There was somewhere a newer version of the manual from '88 with changes from 2002. But I don´t have the link at hand. When I find it, I´ll post it here... I think many people wouldn´t like to fly the Huey anymore if the real limitations where implemented. And EGT is by far the most unproblematic value of the real T53-L-13B. The Belsimtek T53-L-13B has wrong values in the DCS Huey. That said, I personally would love to have the real limitations (Ng, rotor rpm, torque) finally build in. Fox

Hey Mike, just watched your replays. Wow, that is quite an extreme FOV. Why do you choose this FOV? You do have TrackIR. Use it. With such a FOV it is hard to estimate distances and, more critically, your height. Press RCTRL+Enter to see you inputs. In both tracks you pressed the left wheelbrake during the takeoff run. Why? Maybe your left wheelbrake is double assigned. Check that. Use the flaps in the take-off position. And don´t forget to flip the gear-up guard. It will make life easier, once you´re airborne :D I don´t recommend to hold the brakes while accelerating the engine. Start the takeoff run without brakes. Increase the rpm to taxiing values first. As soon as you move, with the stick fully aft, check that the tail wheel is locked by pressing and releasing the wheelbrakes, one first, then the other. Then increase the throttle to 3000rpm, within 2 seconds. Start to count in you mind twentyone...twentytwo. Start to move the throttle when you start to count, and when you finish ...ytwo the throttle should reach the 3000prm position. Do some dry throttle movements in this manner to get a feeling for it. Don´t hesitate to use the power. You need it for the take off run. Always have a look at the turn indicator and keep it centered with the pedals, not the brakes. Keep the stick fully aft up to 120km/h. Then center it, so that the tail comes up. Then pull the stick again to get airborne. Once in the air, don´t pull to hard. Push the stick forward again to fly level a few feet over the gound till you accelerated to 220km/h. Then start to climb. Now you can retract flaps and gear. Fox

Also nur zum Verständnis: Fire, du hast in deiner mission slots a bis d zur Verfügung und d ist so n spezieller Slot. Wenn nur abc besetzt sind, sollen diese player über das comms Menü (F10) eine custom Aktion auslösen können. Sobald aber ein player im slot d ist, soll dieser comms Eintrag für abc verschwinden. Verlässt der player den slot d, sollen die player abc den Eintrag im comms Menü wieder zurückbekommen. Ist das richtig so? So hab ich dich verstanden. Oder willst du das gesamte Menü, F1 bis F12, welches normalerweise über die Tastenkombination eingeblendert wird, über den besetzten client slot einblenden lassen. Und dann wieder ausblenden lassen, wenn der spezielle slot nicht besetzt ist? Fox

Wie kein Funk ohne weiteres? Verstehe gerade nicht, was du meinst... Im MP funktioniert alive und dead für Clients wunderbar. Auch, dass damit radio items ins comms Menü aufgenommen oder entfernt werden ist kein problem. Fire, die beiden Radio.miz hab ich für dich gemacht. Schau mal rein, dann siehste, dass es relativ einfach ist. Da braucht man keine beweglichen Zonen. Fox
