  1. Thanks for you posts @fapador and @Calabrone, regarding what I was referring to and Calabrone asked to be more explicit, it's the fact that when flying staright & level, if I give the heli a roll input, and then retrn the stick to neutral, it tends to rapidly return to level flight as if it was a fixed wing aircraft with huge dihedral effect. It's mentioned in the links fapador offers above, among other problems...
  2. Very old topic, but the other day someone was commenting on the tendency to return to level flight when perturbed by cyclic roll input and return o fthe stick to neutral that can be experienced in the DCS UH-1H as opposed to the RL couterpart. Since I've never flown any sort of heli IRL, even less a UH-1H I can't but try to look at the physics / maths of the flight model and try to find out if it look plausible or not, but the user commenting on it did have experience in helis, and he pointed out that the real UH-1H would not return that easily to level flight when cyclic roll is imput. Interested in finding out more about this...
  3. Been following this interesting thread. Lot's of important and informative infor from all of the participants ! @fapador, while I do look fwd for both DCS and IL-2 one day finding the time to adapt their FDMs to a "curved Earth" gehoid model, mainly becaus eof the impact it'll have on scenery design for thos who have the tedious task of creating it, but also for how it affects Earth - Air missiles and rockets like, say, the V-2, supersonic aircraft and so on, I don't really thin it'll ever impact the "ball" in a turn coordinator, or the string in the canopy of my glider This being said, I am trying to understand it it's really down to a quirk on the ball modelling, or any other factr, that affects the described behaviour. The Moskito turn & slip instrument also behaves rather strangely, but this turn around in terms of the inclinometer needle, which keeps bouncing from left to right to left to...
  4. The most useless instrument in a glider for landing ... Actually, IRL I usually look a last time inside the cockpit to check speed while turning to base... So, in most ww2 simming I just do the same and use mostly visual references. Some ww2 axis fighters weren't even VSI equipped. The K-4 in DCS is, but in IL-2 most of the 109s and Fw have no VSI... Don't remember the bombers. And... why did I post this ? Because I found the same difficulty in finding it hidding behind the gunsight / uv lamp, but I treat all of the ww2 modules like gliders on approach ad landing, just checking the speeds for proper flap / landing gear operations, the rest being all visual, and it works great in DCS ( and IL2 as well... ).
  5. Thx - I was about to ask the exact same - Prop and Thrust settngs...
  6. And indeed Yo-Yo's handling tips work - just tested and nailled the takeoff :-)
  7. I GOT the idea that overall DCS ww2 birds tend to overdo the inneficiency of the tail surfaces at low speeds, and even when the propwash is at it's max values during the initial takeoff run... (*)Yo-Yo addressed this postof mine with some interesting notes... Well, after all he knows what he is talking about, so, I'd rather go with his explanation ... IL-2 BoX does the opposite IMO. I'd say a more realistic representation would be somewhere in the middle... IRL I'm freed from having to deal with those rotating props since I only fly gliders, but some, specially when heavy or under x-wind opperations can become rather tricky when it comes to directional control during takeoff and landing, and yet, I never came accross the diificulties I get into when playing ww2 birds in DCS World. And - Yes! I am aware of all of the aerodynamic effects, and math formulas supporting them in a computer-based simulation All of those WW2 birds that do't have a lockable tailwheel suffer from that "quirk". Even the 109 can, due to it's even more inneficient tail... The Spitfire is easier than the Mosquito to tame. Watching rw footage of Mosquito taking off doesn't look anywhere as "complex" to control during takeoff. In the bellow video the pilot advances the throttles rather carefully / slowly:
  8. Not related but your video also exposes yet another problem - sideways friction apparently is weak, and during the takeoff run we can see the wheels sliding to the left, with the aircraft axis well aligned with rw centerline...
  9. Using DCS in VR must really give a different feel Wow!
  10. And you did the right thing and a great job ! I am sure many around here don't know some of the things you summarized pretty well !!! Congrats !
  11. What War ? In the OP all I can see it's a summarization of altimeter settings.... BTW, to some extent ( limited but modeled ) DCS also models QFF, since it does vary geopotential height due to low / high Temperatures. You can try it by flying around in mountainous terrain with a same base QNH, and then varying season from Summer to Winter and the temperatures way above or way bellow ISA ( 15 ºC ). You'll find that in Winter with low temperatures in DCS for a same QNH setting you will actually be at a lower height for the same indicated altitude ( read in your altimeter ), while in Summer at high T you'll be higher for that same indicated Altitude ( same QNH ).
  12. Yep, I made the initial post because I found that the lower needle, that indicates the direction and somehow rate of turn in that direction, appears to move somehow strangely from side to side even when I was not turning significatively in the indicated direction, but, after watching that last Spitfire cockpit video I begin to think probably it's in need of just a bit of fine tunning by the devs...
  13. -0303-, very good observations, and indeed I also found it rather "mute" in the Rapide.... Here's another video where it bounces a lot more in a Spitfire
  14. @scoobie, yes, exactly as you describe. The lower needle: http://spitfirespares.co.uk/Instruments Turn and Slip and Artificial horizon page 15.html Couldn't find any footage of the original Mossie inflight with cockpit perspective and the ones still flying already use a "modern" turn coordinator, but on the bellow linked footage of a DH 84, the turn coordinator is clearly seen, and it's turn needle doesn't behave anywhere near the one in the DCS Mosquito
  15. @NineLine, the video above is a good demosntration of the effect. Just monitor the inclinometer ( lower ) needle on the turn coordinator, and it's rather peculiar bounce from left to right to left to.... due probably to an overdone sensitivity to the forces that affect it IRL (?) and certainly not observable on the Spitfire...
  16. Look for UTM conversion. There are loads of online converters, usually basedon the WGS84 ellipsoid , but not only. I woukd rather prefer, though, that DCS used a "curved Earth model"
  17. Professional Flight Model appears to be the highest in the rank of detail and accuracy when it comes to flight modeling in DCS World. I wonder if ground effect is modelled at a single reference point for the whole aircraft or if destinction is made between, for instance, wings and the tail surfaces ? When during landing, right above the runway and bellow one wingspan of height the ground effect starts increasing, does DCS PFM take into consideration the peculiarities due to it's effects over the main wings and the stabilizers / elevators, expressing itself also as a pitching moment ?
  18. If we set the weather in the weather menu in the Mission Planner and then select a Weather Preset they can be perfectly out of sync. Would be great if it was possible to enable weather themes but let the sim choose the most adequate one when weather parameters like rain and storminess are also set. Of course additional weather themes, with ruin and thunders, fog, etc... would have to become available.
