PFunk,
I hope you haven't completely given up on the x52 yoke. I use the full system (stick and throttle) in PR and have had a great experience so far. To top off a few of your questions:
1. The "pitch factor" option is a setting for the mouse. If your mouse is old and has only 600 dpi. you would set your pitch factor up to a higher value. With a mouse that is 1000 dpi or higher(gaming mouse), you might need to set the pitch factor lower because your mouse is VERY sensative and the option to lower the sensativity is great. For some it is the diffence of having to reset the mouse on the pad or not, and we all know resetting the mouse in an attack dive will result in a nose plant on the ground.
2. In my testing days- I found that the mouse settings, pitch/yaw/sensativity had absolutly no effect on my joystick. Infact with the x52 yoke- the sensativity is set by the manufacturer and can't be changed with any simple "options" setting ingame or with the SST software.
3. The negative trust thing, as I am sure you have found, if you go full negative throttle- the aircraft basically falls like a rock with no steering... so lets say you set the throttle to negative 25% you will have a slow decrease in altitude but still maintain control over the aircraft correct? Even at negative 50% thorttle you will fall fast but still be able to control your movements... Full negative thorttle is much like full positive throttle- hard to control.
4. Calibrating the system:
At first I had some trouble setting buttons in-game. Some of the extra buttons on the yoke were showing the same button assignment for the throttle buttons. So BF2 was saying "Duplicate setting found..." I had to use the SST software to set each button on the stick and throttle individually. Lets say the thumb button "C" on the stick is what I set my flares to... in the game I left "X" as the button to deploy flares, but in the SST software the thumb button "C" had to be set to the key "X", save/load profile and good to go.
5. The only in-game settings that need to be set are pitch fwd, roll right, steer right and throttle. If you are setting pitch fwd and push the stick forward all the way, it should set both fwd and back to the same axis. Same with roll, twist and throttle. There is the problem some people have with the reversing. They try to set throttle up and throttle down when you only need to set one of them for the settings to see the axis. If BF2 doesnt see the axis after trying to push the stick forward for fwd. try setting pitch back and pulling the stick back. One or the other- not both - untill it is set.
I had to play with it for days before I figured out ways to make it work. I had the same problem you described earlier in the post- last year- that you were having the "mud stick". When I first started using the stick I was under/over correcting everything. If I was tipping forward a little, I would pull all the way back on the stick, and it would damn near flip me over- or it would flip me over and "FAIL" would appear across team chat... So I started trying to be really soft on my adjustments only to find they were having very very little effect.
It turns out to be more about your throttle position than anything. At hover, my throttle reading on screen says 23% and the slightest touch on the stick will send me in whatever direction- so softness is the key. In an attack dive, the throttle cant be full if you expect to recover from the dive. If I am diving in and at full throttle, the stick has very little pitch effect other than down(forwad) >.> Pulling back on the stick only keeps me in the dive- BUT as soon as I drop the throttle to less than +75%, the stick becomes responsive and the dive can be saved.
I have helped a few people set up their joysticks and pratice in trainning servers. The first tips I give are: Take it slow at first, slow will become smooth and smooth will become fast. Everything you do in an aircraft is planned before you do it. 2 seconds before you actually start turning, you should be thinking about recovering from the turn and making the adjustment. It really has to do with throttle, not joystick adjustment. The delay is actually realistic. Every aircraft, especially helichopters have some delay- That is why you plan ahead...if you are pitching forward and yank the stick all the way back, you should ready for the extreme "pitch back" movement. If you were pitching forward and only pulled the stick back a little untill you actually get some of the adjustment to happen, you will become much more smooth. Make adjustments 2 seconds beofer you think you will need them... I guess that is hard top explain.
At neutral throttle the heli is very manueverable but has no speed. If you tip the nose a little forward- the heli will gain speed without throttle interaction. You can try this... go up to 300 alt in a heli and hover. once in a stable hover LEAVE the throttle in its position and assume an attack dive angle. The speed on screen will increase but your throttle position will remain the same. Doing this will increase your chances of recovery from the dive angle because the stick will still be responsive at "hover" position. When you pull the yoke back the pitch will change and you will assume a hover again with some practice. After you tried that a few times, try getting to the hover and assuming the attack dive BUT decrease the throttle to about negative 25%... the effect is basically a stall. Your nose will be pointed on target and your speed will remain the same for a few moments untill falling speed and attack angle catch up with one another.
As I am sure you have read, some x52 owners have problems with the yoke re-calibrating while they are flying. I have had the same issue since I have owned this stick. The simple solution is to unplug/replug the stick in. Some people recommend using a different USB port when you do this. The same port works fine for me and resets it back to normal. But it sucks *** when it happens and you are trying to fly because you either have to fight it to a hover and quickly do the plug thing, or land. I also have the LED flicker problem where my stick lights up like the 4th of July. I have owned the stick long enough to be outside the warranty so I have taken it upon myself to "fix" the problem. I opend the yoke and noticed some of the wires were damaged. Atleast two wires were smooshed flat and likely to be the cause of the short in the light. I cut the wire thinking I didnt need lights anyways, only to find it disbled the X axis

. So I took apart another old gizmo and raped some wires from it- rewired some of the damaged links and have not had a problem with the stick since.
Best thing you can do is practice with it. Give it some time and you will be as good if not better with the stick than the mouse/keyboard. I say it takes about 1-2 weeks of constant practice to get it. And I am always willing to give some lessons! Remember- slow is smooth, smooth is fast. Every action must be planned and taking place 2 seconds before you do it. (Delay)
