  1. Wait, do you want a gyroscopic tracking or one that relies on magnetic bearing!? I can see how one would make one in arduino, but I would expect huge drifting issues over time that would imho make it too time-consuming to produce for the result you should expect. That being said, it sounds like a great project and I am almost tempted to make one of my own for fun...but not for using in game. EDIT : If you wanted a magnetic bearing tracking, that would only give you a 1dof heatracking which would be...let's say limited.
  2. Find a wingman and fly as a two-ship.
  3. I feel like the extra fuel is going to be more valuable than another AIM-120 ;)
  4. The stutter is DCS loading the terrain, which is taking some time as it is on a HDD instead of a SSD. It's not because it isn't on the OS drive.
  5. So Sweeper and I were playing on 104th doing some 2 vs Unknown fights. Just as we start egressing, I picked up a dogfight between a friendly and a foe and decided to help him...We must have sorted way too fast as there was a third guy lurking around...Enjoy!
  6. Ohhhhh boy another one of these XD As of now, F-15 is probably the most efficient platform and the most recent model. SA and BVR-wise it outranks everything else. In WVR it lacks off-boresight SRM and might not be as good as the 27 in some circumstances, but is still very efficient.
  7. I don't see how this is a relevant source. A user-made document on a forum, and all the references are either from other forums or outdated GAMEs (Lomac...) [game used as not a simulator] and the paper references are from TOM Clancy and a real book that seems like a general military aviation encyclopedia.
  8. 1-ED is very reticent to update the FC3 planes, so it's highly unlikely that we will see these in the next years. 2-If you are always dying, why do you want better missiles that your enemies can have? Train / read a bit more and you'll be fine, what ever the armament.
  9. Just an educated guess, but the size of the fins is function of the missile's mass. These fins are most likely the minimum the designers thought was possible while maintaining a good maniability. As the Sparrow is heavier than the AMRAAM, putting fins meant for a lighter missile would probably increase it's range a bit, but completely destroy it's maniability.
  10. The fact that many planes are illuminating the target doesn't change anything though. If it did, you and your wingmen would have a big flood mode and you wouldn't be able to sort between targets. Each plane has it's own frequency link with it's missile, and it even changes between missiles on the same platform IIRC. 2cd video, maybe it's because I can't see too well and mess with the TacView, but it seems like he notches to up to the flankers shooting very short range shots, I don't see what's crazy too much. The first one is funny as hell though, I'll give you that much haha.
  11. In that case, might want to look on what servers/missions you are playing and decide to have realistic experiences, the level of realism of the game won't change anything if you rush yourself into furballs at every occasions you get.
  12. So I had some time to waste and tried to see how the thread was still alive, so 2 things : 1) Why do you guys think this is wrong? Anything aside from guts? 2) I made a nice little graph showing the max altitude the missile should be expected to reach if there was no atmosphere at the moment the engine was out (so WITH acceleration drag) considering variable G. Of course, these will be a couple tens of thousand meters off, but should get the point across. (of course, this is based on what I posted above) H[1]=Launch altitude, H[2]=Max altitude, all in meters.
  13. Why do you want to post screen shots? As I've shown you can expect that kind of altitude from a missile that can reach mach 4 in an horizontal launch at 8000m.
  14. Upgraded version : if we consider the mass M, the mass of the missile without the engine, we get : 1/2*m*[1331^2-411^2]=9.81*m*h thus h=81684m Thus max height 88000m... This is legit, as the energy needed to accelerate and make the engine climb would be lost as it was burned! EDIT : This however, is with an approximation of drag, as I said, FOR THE ACCELERATION ONLY, I forgot to say that earlier, sorry, taking the rest of the drag into account takes MUCH more calculus, and while I could do it, i'm entering my finals...so yeah...
  15. First off, missile talk. An AIM-7E has a mass of 197Kg, and a motor mass of 42Kg(https://forums.eagle.ru/showthread.php?t=131806&highlight=missile+mod) making a Motor/Mass ratio of 0.213198 The AIM-7M has a mass of 231Kg and a motor weight of 62Kg ratio of 0.2684 The R-27ER is a missile based on the same category as the 7m, but with basically more propellant, so it is safe to assume the fraction is AT LEAST of 25% I did my own test with a mach 1 (1480km/h=411m/s) launch at 8km (26299'=8015m) , level. The max speed the missile reached was 2421KTS IAS (2662 KTAS = 1331m/s) Now, the drag from a constant altitude launch > the drag of a missile launched vertically, so I will not consider the drag, as it is already capped over what the missile will experience vertically. The energy given by the missile was 1/2*(350*0.75)*[1331^2-411^2]=210346500 J (assuming missile mass = Launch*0.75) This considers the energy given only to the missile itself, without the energy used to transport the engine that hasnt burned yet. [Aka minumum] Now, assuming constant G[maximum value] and a mass of 350[maximum value] we get 350*9.81*h=210346500 h=61262m, making a final height of ~70 000m, with an initial launch speed of 0, and assuming the missile brings the engine the whole way up! So, i've made VERY rough approximations that REALLY reduced the missile's performance, yet it still managed to get pretty close to your altitude, so it makes a lot of sense to me.
  16. Yeah, you have to edit a few controls at a time and save quickly before it crashes...It's sadly normal :(
  17. Sadly, after 5-6 hours of fun, I wasn't able to. Haven't had all the classes I need to do that yet, but mainly, I would need one flight point in F-35 where I would be able to know acceleration (mainly z), AoA, pitch angle, speed, altitude, TAS and thrust. I thought about doing it with take off (as we know the T/O speed will be around 75m/s|150KTS) but the F-35 has slats which is problematic, as the point of having this point is to find the AoA>Cl coefficient, which wouldn't be valid with flaps/slats. I could also take stall AoA, but again...slats. And besides, calculations with Bernoulli's law in transonic as you did aren't accruate so there's just too much margin of error to make it worth while :(
  18. It should, and it does. Try it with shooting at missiles if you doubt. Now for the sun, remember that it might blind the seeker completely, so the IR-blinding size of the sun is more like 10-20° of radius, giving a lot of room for error on a pure sun tracking.
  19. Contrail will vary depending on the humidity and the temperature of the air : the colder/the more humid the air is, the lower you will contrail. So yeah, altitude varies, I remember contrailling at 5000' at -30°C. Usually, you can expect them to be from 24-29000' up to ~40K'
  20. Yes it shoud! :D EES= engineer equation solver / wolfram alpha on super steroids
  21. The drag function [ D(x) ] will not be the same at different altitudes even with an air density correction ( you'll need a higher AoA for the same lift at a higher altitude, thus more induced drag at the same TAS ). While it could seem as an ok approximation, you'd get 1.44 times less lift, which would get you falling down pretty quick EDIT : might get you an equivalent time with EES if I get nothing to do...lol
  22. Fair enough, minimized rudder than, just compare it to any plane of it's size and you'll see. And what's the discussion about? The best WW2 turn fighter?
  23. Actually, the -35 has been at similar AoA (at LEAST 110°, most likely more if you search). Any high AoA (past stall point) will decrease lift and will leave the aircraft in a super-draggy state. While this might not seem good in a fight, just remember that the plane will have a 9X, you don't need a high STR in many situations. BTW flying wing means no rudder...
