Hi folks -

Just coming back to RoF and re-learning the game.  One problem I am running into is that I am now using a Hotas Warthog and no matter how much I calibrate the stick in windows before entering RoF I always seem to have a nose up trim while flying.  Anybody else run into this?   Any clues to a fix appreciated.

In Options/Responses adjust you "Pitch" to achieve the desired effect.   This is my Nieuport 17 "pitch" curve,your's may be different.

What plane are you flying that this happens in, if it's the se5 then you have trim that you can adjust, right ctrl and up and down keys adjust your trim. The tri plane is the same but can't remember the others.

Since I get this in every aircraft I fly I'm guessing that I will need to do a custom pitch curve for each, but I will check the trim controls while in an SE5 to see if that is enough to zero it out. 

 

Thanks for the clues guys.

You can set the curve to be generic for all aircraft if you want as most seem to have a nose up attitude. I have mine set at 10 down across the board.

It varies plane to plane, some 'need' the nose pulled down more than others.

Some pilots will pour scorn over you for using any curves, but I'd be surprised if anyone flies actually flies a Dr1 without pulling the nose down...

 

My rule of thumb is near level flight, with a slight bias to climb. (obviously this is relative to a particular speed - your plane's lift should increase with speed and vica vera.

 

HillBilly's graph looks text book in the way he's smoothed out top and bottom after placing the 'pitch point'.

Beyond that with a little experience you'll start to feel if a particular plane needs specialised tweaking.

(As a side note there may be one or two planes that have a particularly strong reaction to stick forward (Camels !!).

That being the case I'll slow the initial response to that a bit with a negative S Curve so the top and bottom halfs of the graph will look different.)

 

Only mess with the curves when you identify a need to, you'll soon get the hang of it.

Good luck !

FWIW, I used to use both trim curves (the kind HillBilly provided a screenshot of above) as well as so-called "S-curve" exponential curves, with a more horizontal area in the middle, to make the stick less sensitive around center.

However, I too am back to RoF after a long lay-off playing other things, and have decided to try just flying the planes without any curve modification at all.

This requires that I hold forward stick in level flight - which is a bit annoying - but it has an interesting effect when in a turnfight:

 

Because you've got so much pre-set "up elevator" (nose pitch up), you actually don't need to use tons of stick travel to make your turns (i.e. once your plane is banked, it's already turning at a pretty decent rate with neutral elevator stick). Because of that, you don't need to use as much stick travel in the turns (due to the preset trim), so you actually wind up with an effect not too dissimilar (and IMHO in some ways better) than using an S-curve to introduce exponential around center.

In any event, I'm having an easier time than ever to pull lead for deflection shooting, and my accuracy is now frequently at 15-20% or better, whereas before I was lucky to break 10%.

Just something to consider!
 

S!
