I was lucky enough to get a similar crosswind out of parking and it did help! The defaults seem to have been set at -1000. Which I think means the effect should be infinite? That explains why you can’t even roll from a stop.
I did think with the 200/90 setting there was a sudden transition on takeoff that didn’t feel quite natural. Perhaps some tweaking of tire friction values with lowering those are needed too.
Landing felt a little like I had landed on rails. I had held the flair to just over stall speed.
What do you think of setting “ground_crosswind_effect_zero_speed = 65”? That’s just under stall speed.
If I were going to set this value for the YMF5 I would choose 40 knots. The aircraft is very light on the wheels at 40 knots and by 80 you are rotating. I haven’t flown the 172 enough to comment on that module.
The opposite. It means the aircraft will always experience full crosswind effects on the ground.
I’ll say it again: avoid high min/max values - ie a min near or above Vr - if you want realism. The higher you set the minimum, the more you are removing the effect of crosswind. It will make for nicer take-off and landings for sure, but so does turning on rudder assist. This is no different if over done.
I’m not sure opposite, I think that’s what I was saying. At the default of -1000 it isn’t possible to move the C172 in a straight line, from a stop, perpendicular to a 5 knot crosswind. It requires additional braking along with 100% rudder.
I have no idea what the real behavior would be like.
Ah I gotcha. So some Devs (eg Working Title) set the min/max to -1000 just to remove it as a factor. You could equally just not have the variable.
They use the lateral tire friction scalars to stop the unrealistic behaviour you describe.
Personally I like to use a combo of both. Some low number min/max values to prevent the really unrealistic movement that happens in even light winds and then enough lateral tire friction to allow a take off at max demonstrated cross wind whilst still tracking centreline using the correct crosswind technique.
If you just bump the min/max up there is basically no weathervaning and you don’t need to use rudder, ailerons etc
So the 172 is quite light and high wing, so more prone to vaning.
I would start with lateral friction values of 2 and increase progressively in steps of 1 until you get enough friction to keep tracking with a 15knt left cross wind without totally maxing the right rudder out. Then you can try fractional values.
Another benchmark is to have a 15knt right crosswind but still not have to use any left rudder - but that might also mean increasing prop-wash and it starts to get a bit more complicated then.
Did anyone do a test with making the vtail area orders of magnitude bigger than what it should be, without any of the crosswind values filled in? If the area is correct, but it’s being affected by a hidden scalar, or similar, that might expose it.
Can you eliminate the crosswind effect entirely until the wheels are off the runway? The sim usually gives an indication the weight on the wheels is light by the intermittent sound of the tires. Perhaps set the min to a high value, and the max to just above the roll rate? 75 and 80?
Yeah it’s an issue that devs such as FlightFX, FSReborn and Carenado don’t seem to get. Carenado have recently opened the Mooney for sale on their own web store though and FlightFX have the HJet with Orbx but the rest of their fleets are MP only currently.
Well, selling through the Marketplace only may make a lot of sense for a small dev. What would be better is if they tuned their aircraft and included that info in their marketing.
FSReborn I know is looking closely at this and you should expect their aircraft to be well tuned.
