Takeoff Roll Behavior
-
I've flown the aircraft twice since the update, and both times I've struggled to keep it on the runway during the takeoff roll. It will not stay straight and takes a lot more rudder input than before.
-
@owlinflight Could you let us know if you have the "RUDDER STEERING AXIS" option enabled or disabled on the Aircraft page of the EFB? And is that the same option you were using prior to the update?
Some changes have been made in v0.1.2 when this option is disabled, as the nose wheel steering is now affected by the aerodynamic effects of the rudder at speed. However, this may have introduced the side effect of the rudder being more sensitive during takeoff and landing.

Whatever this change was I hate it. I've done a few flights now, and it is utterly uncontrollable on the ground on the take off roll, it just wants to hard turn off the runway. I've tried turning it on and off and off and on and it sometimes works letting the plane roll nice and straight down the runway, but it is so inconsistent. I don't have a dedicated steering device and need to use the pedals, I have Honeycomb Alpha/Bravo and Logitech foot pedals.

@melon I quite second this. The plane feels maybe a bit too light and when you have a slight crosswind, you struggle to keep a straight take off. But that's maybe how it behaved on the real thing.
For your problem, try adding more curves to your rudder axis so as to make it less sensitive. -
@celti It's not the wind (although that can be annoying at times it can be countered), here the plane HARD turns you can command full rudder the opposite direction and it wants to do a 90 degree turn to the side. There is no amount of curve to fix that. Especially since it was not a problem until the latest update and toggling the Rudder Axis Steering in the EFB fixes the issue intermittently. Once you get to like 80 knots or so its like someone grabs the wheel and locks it over. Last flight I did out of Arlanda had wind near straight down the runway and the plane was not having a bar of it.

Landed at EBBR tonight and the issue I faced was that on the rollout it was pulling hard left and I had full right boot in just to stay on the runway. That behaviour continued all the way to the stand regardless where the wind was in relation - felt like the nosewheel was set to an incorrect centre position. It was pitch black and raining so didn't do any investigation but very strange - will do a less intense flight tomorrow and see what happens.

Has a solid fix been found for this? I experience the same problem. Once I begin the takeoff roll it feels like the aircraft is riding drunk on a bicycle. It’s all over the place. Landings are even worse. It’s a shame really because everything else is great.

Yesterday I spent some time identifying the problem and came to the conclusion that the inappropriate behavior of the F28 is over-sensitivity to even the smallest crosswind during running on runway. The higher the speed, the greater the deviation. Even with almost full rudder pedal down to opposite direction at the end of the takeoff run with a crosswind of 5-7 knots, the plane turns 45-50 degrees forwards cross wind direction . The same behavior happens during landing. As the speed decreases, the deviations decrease. There are no problems with nose wheel stability. Just put the wind 0 knt in the simulator or turn on auto rudder and problem immediately solved. There's definitely a problem with the dynamic code. It's need to reduce the parameters of crosswind influence.
The settings of nose wheel in EFB have nothing to do with it.
With the current parameters(behavior), the plane kills everything that was done perfectly before. Very upset. -
I just did another test flight and I can say that, if you want to fly in real weather and less stress and don’t want to struggle with plane every time, then go to Settings-Assistance options-Piloting- Auto Rudder ON.
Currently the only option to finish the flight in a good mood. The rest is up to the developers activity. Still waiting for a fix in the next update.
