U-2 Force feedback incorrect centering forces (MSFFB2)

[E_Davjack]

Force Feedback centering force is off for the U-2 in flight and on taxi/takeoff.

 

On the take off roll, the centering force of the MSFFB2 (usb, grey trigger) is forward and to the left.  This does result in aileron deflection as shown, so it is not "centering" the controls with this force, it is pulling the control surfaces that direction for some reason.  Once flight speed is achieved, the stick centers the ailerons, but is canted forward at ~30ish degrees (see photos).  This does not result in level flight, as a very slight forward pressure is required to keep the nose down.   On the ground, fully stopped, there is no FFB pressure and the controls swing freely.  Once you get moving, the stick pulls into the position in photos 2 and 3, and once you get airborne above stall speed the stick centers to photo 1. 

 

I have tested my stick with the 109G6, as well as the Camel, and they both work fine as usual with the FFB reacting properly to the adjustable stabilizer on the 109 and both planes taking off/cruising normally and reacting normally at all speeds/AoA.

 

First photo:  Normal cruising flight center of force.  Second photo:  stick at fully bugged deflection shortly after take off roll.  Third photo:  during takeoff roll, showing the aileron deflection from stick force as it recenters as the aircraft gains speed.   (paused, stick left in the position of centering force for the photo).

Does the U-2 have any trim controls? 

[E_Davjack]

Nope!

I'll be back home after the 10th of Jan and (if I but the U2, which I probably will) I'll let you know if I have the same problem with my G940.

I have the Logitech G940 and the same problem happens with several planes, especially the P-39 and the U-2.

 

In the particular case of the P-39 I just assumed it's unflyable. The U-2 reminds me the global RoF behaviour in which you ended with a nice pain in the wrist until the individual axis curve adjustment was released.

The Flying Circus planes I tested, Pfaltz and Dr. 1 are flyable. All the planes I tested with adjustable trim tabs are broken (Pe-2, LaGG-3). Adjusting trim tabs doesn't affect stick forces at all. The planes also want to roll to the right all the time. This cannot be engine torque effect, because the twin engined plane is equally affected as the single engined. 

 

The FF probably only exists because the developers thought that there would be too much crying bfrom the few people using FF if they leave it out. The implementation is half baked and I don't expect it to be perfected.

I did some more testing. The 109, 190 and Macchi are fine. They all have one one thing in common. No in-flight adjustable trim tabs and an adjustable incidence horizontal stabilizer. By far the most unflyable plane I flew was the duck. It has a ridiculous pull to the right. 

 

I just got myself a MS FFB2 for 25 bucks... I might just reserve this thing for the Flying Circus.

I might add that there's nothing wrong with the fact that the planes pull into any given direction, it's just that the direction and force should be dependent of many variables, most importantly airspeed, and there should be a reversal once pass the trimmed indicated airspeed. What happens as it is when you are using FF the simulators control "law" changes, and in flight the plane will fly straight as long as the stick is centered. This is quite correct. But what is missing is the variable stick forces there after. The stick forces only vary according to the airspeed with the same forces on both directions (in planes without the inexplainable pull to the right). Actually it's quite like flying Aces High with "combat trim" engaged, and it could be used as an exploit at least with the Flying Circus planes. They are a lot easier to fly with FF on.

 

I do enjoy this simulator immensely as it is, but it would be nice to have this aspect finished at some point.
