Realism, whats missing?

I bought rudder pedals instead.

Probably the best reason I've ever heard for splurging on some rudder pedals!

On realism the fact that IL-2 does not model 3D mass distribution leads to less than real rotational results.

I'd be interested in seeing the MoI numbers, as well as all the other parameters.

At any rate, from the flight modelling point of veiw, I think the very point of "realism" in IL-2 isn't so much about getting the absolute correct results for a particular aircraft, as much as it is about getting the relative performance between all the aircraft in the game within an acceptable bracket.

Thread title is?

Using a P51 in IL2 and DCS.. I tried to snap roll it using full elevator and rudder with no aerolons. Engine was on idle to minimize torque and propwash.

1) The IL2 replied with immediate wing stall and roll
2) The DCS P51 made an attempt to yaw and nose up.. and refused to do anything. It hung there wobbling, as if in a software loop that was going nowhere. They went off their rockers when I pointed this out....

Having found that great instructional video that I've posted, I set up both aircraft turning with full yaw and slight cross controls, so as to keep it just on the stall zone. I then applied full aerolon which should have induced a stall.

DCS again did nothing and rolled in the direction of application, still refusing to stall when I applied complete cross controls.
IL2 also did not respond fully but did wobble a bit... and was much slower to roll over - but effectively showed that this FM wasn't modeled that much.

Similar results with my (quick) testing. The plane flips over in DCS but does not enter a stall / spin like in IL2. Even in IL2 it is hard to stall it properly. Which one get the job more accurately I do not know. I do know that the landing in P-51 is much closer to what you can see in YT videos than in IL2 where one can put it down soft and easy (ground effect or low speed handling over modeled??).

EDIT: I was too gentle with the controls. Cut back on power suddenly coupled with full left of right rudder and a touch of positive elevator and she snap rolls and stalls immediately. I'll try to do those other maneuvers show in the video you linked.

Which version were you testing this in? IIRC the whole module is still WIP, from sound etc..

Seconded.

Hi, new here.

I used to fly Piper Tomahawks a long time ago. I do think this sim would help non pilots in an emergency with such a plane.

About warbirds, I came across this while reading reviews on IL2 1946:

http://www.amazon.com/IL-2-Sturmovik...owViewpoints=1

"I've been a pilot for over 40 years and have flown everything from '20s biplanes to Navy carrier jets...and this sim is awesome.

Note: it is on DVD not CD as stated here. And it is NOT a game. There is a significant learning curve involved to successfully fly these aircraft in full-on realistic mode. It does have 'simple' modes that make it possible for anyone to fly, but don't think of this as an arcade game in any sense.

Trust me, if you can fly these birds in full realism mode, with a little time flying under the supervision of an instructor you can fly the real thing. Here there are fewer cues (just sight and sound), but in real aircraft you also have so-called proprioceptive sensations too (the seat of your pants, for one), among others.

Buy it, you'll like it! The graphics are gorgeous, the scenarios are amazing. You won't find modern airliners, but you'll find most of the WW2 machines (Russian, German, Japanese, British and American).

A flight over the cliffs of dover at sunset in a Spitfire may bring tears to your eyes...it did me."

What do you think?

Watch your six, Alex

Closest I've ever come to losing my lunch in an aircraft was when a buddy and I took a Tomahawk up over Williams, CA for some stalls and falls years ago during my Coast Guard days. Fun airplane!

I started with DCS123, and it's nearly the same in DCS124, with the exception that there seems to be more rudder response - I haven't changed my stick settings. Same for IL2 V411 and V412.

DCS is definitely the better feel sim. I was actually very ham-fisted with the DCS stick/rudder inputs.. but to no avail.

Here's an external view of Free flight over Poti (V124) where I show the control surface inputs.. and the P51 refuses to behave

All controls settings are Linear and 100% plus no 'fore'play

I can get DCS to so called 'snap roll' if I apply aileron in the direction of roll... but this is not the 'official snap roll', which is the application of elevator and rudder only - as the guy does in that AG video.
He then applies momentary and then opposite aileron, after the roll, to help bring the wing out of stall.

Maybe a full fuselage tank might help, but this is not the idea .

[K_Freddie]

Now if TD can take a sample out of DCS modelling (and extras) and give it the same feel... which I feel would not be too difficult, coz AFAIK, Oleg's FM consisted of a core FM with plugin parameters for aircraft - it could trounce DCS completely. Maybe I can help - please

DCS cannot yet compete with IL2 (forget CLOD) for overall WW2 aircraft.. and I reckon they probably never will.. IL2 has a massive core base and requires a few quirks here and there to bring it into the next/future generation sims.
