Fixing Roll

[jimbop]

I've just re-read the entire thread and I am now more confused than before. Can someone just explain what is causing the Hurricane FM to roll clockwise? Please don't say torque because the prop spins clockwise.

If it is gyroscopic precession then how did WW2 pilots manage to trim their aircraft for hands-free straight and level flight as quoted in this thread. Or didn't they? If the answer is rudder trim then the FM is wrong since you can only eliminate roll by using excessive rudder trim which causes side-slipping.

In IL-2 1946 you could use Hurricane's elevator and rudder trim for straight and level flight, no roll. In CoD you can't (well I can't, anyway). Which is correct?

I haven't flown a real Hurricane (of course), but i have a feeling that this is part of the new FMs and if there's a bug it probably lies in the fact that the effect doesn't get disabled in lower difficulty settings.

To be more precise, it's much easier and as such instinctive to keep a real aircraft from rolling, due to the fact that there's no centering force on the stick (apart from the airflow pressure transferring to the stick through the control linkages, something that depends on altitude and speed) and that a real stick has a much longer throw than what we have.

I find myself wishing I could "like" this post, facebook style.

I use the CH Products fighterstick, Pro Throttle and the Pro Pedals I have the input curves set to be linear in nature and have calibrated them use the CH Control Manager. At the moment I find I need to use about a quarter of the movement range to counter the roll with no slip/skid for level flight at cruise power (so 25% deflection), would be interested to hear if others with these controls also find the same.

Does the Fighterstick have integral trim wheels in roll and pitch to counter this? I had an old game port version that did, and am thinking of buying the USB version for this reason.

Thanks

Thanks, helpful. I didn't realise there was no real centering force. I sense another mod to my x52 pro is just around the corner!

By mis-calibrating the centre for this joystick you can eliminate the roll to the right.

As you recalibrate the stick, hold the joystick to the right when you click a button to record the "centre". Do this each time the calibration process asks you to centre the stick and click a button. When you have completed the process your joystick will have a false centre... just enough to simulate corrective trim to keep wings level.

'Works fine to counteract the torque effect in single seaters, but if you want to fly bombers or switch to another game you will have to recalibrate the stick to its proper centre.

A problem with this is that you then lose some travel in that direction which could mess up roll rate or at least a sensitivity difference between the ailerons?

So after 3 pages, what was the technique to reduce roll ? I do at the moment just trim the rudder, but then your craft is crabbing across the sky, surely this isn't what actually happened, I couldn't imagine BoB pilots being happy with crabbing.

[madrebel]

the italians solved this by extending the left wing of the macchi aircraft by 8.5". left wing created more lift and counter acted the roll.

I trim elevator first, then rudder to remove crabbing, then manually hold against the roll with the stick.
