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...

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...

It's the Super-Meredith Effect

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...

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... ).

Happy Happy !!!!

Has to be easier in the real thing...

Excellent hint @Charly_Owl

Thx - I was about to ask the exact same - Prop and Thrust settngs...

And indeed Yo-Yo's handling tips work - just tested and nailled the takeoff :-)

Thanks Yo-Yo ! Will edit my post

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:

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...

Using DCS in VR must really give a different feel Wow!

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 !
