Yes, you do need to maintain trim during flight as flight conditions change if you want your aircraft 'hands free' (i.e. so that you don't have to apply constant input pressures).

Trim wheels are much better than button clicks for fine trimming. I use a G940 and in the axes tab of the controls config was able to assign three trim wheels from the main stick to the three trim axes. Unless there is a specific issue with CH support, I would assume the method is the same and just double click the trim you want to assign on the right and then move the corresponding trim wheel on the stick. I did have to recalibrate the wheels first.

Likewise, out of the box, I had weird pedal assignment and just had to ensure that each control axes was assigned correctly in the same way. Somehow I had a throttle wheel assigned to rudder.

The reason for lateral trimming of an aircraft is largely related to the gyroscopic effect of the prop. At high revs it will cause the tendency to slowly drop a wing. Too prove the point, try reducing prop RPM and manifold pressure to a slow cruise and you will find the rudder input required to maintain straight and level flight is reduced.

To solve this most pilots either hold a little rudder or preferably tweak the rudder trim. Bare in mind, every change of RPM/Man Pressure will require re-trimming the aircraft, Power, Attitude, Trim is handy to remember.

It's the way it works in the real world.

Indeed, that's what I would expect, I just wondered if the game FM/wind implementation got it right, and why I started trying to nail down the cause of the trim need.

I've solo'd in a glider so am used to having to trim but without an engine :) As you say, during flight if you change power and attitude (which I seem to do a lot in a sim such as this), your trim may well need changing.

The effect you talk about in regards to engine torque I have found most notable and most dangerous when at slow speed with flaps down coming in to land and you think you'd messed up the threshold and apply a touch of power and get it wrong. Too much and over she goes. It's not pretty. In a glider all I did was fondle the air break for power control and there was no torque in that :D

I flew a glider many many years ago, was a fun experience. I have flown most commonly available prop planes at one time or another in my 20 year career. Certainly the real thing is much easier to trim than a simulator as you can not feel the stick or rudder pressure relaxing as you turn the trim wheels.

I have never had the pleasure of flying a real spit unfortunately however with that huge prop and a merlin to drive it the P-Factor would be fairly pronounced.

I was trying to trim the hurricane as it was also pulling annoyingly to the right, though I've read that the hurricane doesn't even have aileron trim, is that right ?

This was with wind turned off and no joystick plugged in. I had also wrongly mapped the 'notch' aileron right and left functions instead of the trim functions. So every time I'd move the yoke, from my perspective, the trim would reset and I was baffled until I figured out I wasn't actually trimming. Then even more annoyingly after I had mapped 'trim' it wasn't making an effect on the hurricanes ailerons anyway.

Are we supposed to fly the hurricane with a constant left leaning ?

I'm not sure about your gaming background, but COD is meant to be a flight simulator, and a simulator of the most powerful and dangerous machines of their day (they commonly killed their own pilots at alarming rates), irl these aircraft took many months of training to just fly competently, and even then few mastered them.

So, to answer your question simply........yes.

I think you may find the constant slight turn to the right with the hurricane is because the rudder is from the off trimmed slightly to the right of centre rather than by default at 0 trim, if you trim the ruder (ctrl + z or x) it stops this constant slight turn to the right. ;)

This is why I miss FFB. One of the first things I learned was to feel (and hear!) the buffet as you approached stall, and how to trim such that you could feel the controls go 'hands off'.

RoF is impressive in this respect and, when my engine is shot out, the closest experience I have had in a sim to gliding. I think the wind noise has a huge amount to do with this.

Ah, well I wouldn't exactly call myself an overly hardcore simmer, I like to dabble mostly, with hopes of being hooked again. I started on LHX Attack Chopper and Chuck Yeager back in the day, moved on to 1942 Pacific Air War, Falcon 3 and US Navy Fighters, found the original IL2 and played that for a bit. In between 1946 sorties I've messed around with Lomac/Flaming Cliffs and recently have bought Blackshark and the new A-10 sim but I've yet to play them to any great degree. I completely passed by the Janes and SU27 games though. My favourite has to be 1942, even though IL2 is great, my fondest memories were with Pacific Air War, probably because it was my first real sim.

So yeah I do understand these machines are essentially bricks with wings that require some modicum of skill to operate.

Rudder trim seems to have helped a bit, I just wasn't using it enough.

Strangely, the 'quick flight - england free flight', I didn't have a problem with for 5 - 6 attempts before, now starts me off with a borked engine, flames coming out of the exhausts and oil splatted all over the pit after about 10 seconds, then the engine loses most of it's power, weird.

Well i think, that this is not right, ive seen some vids of other user flying cod, and there aircraft control is almost rock steady, but no matter what i try, these planes always want to dip, turn right, this sim should not be this hard to control
I can understand some you are saying, But, this is how its ment to be, well if i was flying these fighter in relal life then i would bloody land and tell my crew to sort it out :)

Can we get any offical word from the makers, that this is how its meant to be or
is there a problem?

I have just tested all fighters in this game, and every one dips to the right constantly.
Tested the bomber and they are ok.....
