Take off roll issue
-
@berniev Yes, we know - As I said in an email to RetiredMan, I actally looked at it a while back but my head was in P3D at the time and in that sim the steering / free castoring is entirely dealt with in the Contact Points steering angle, and angle other than 180 means no free-castoring at all.
The extra lines seem to override that, in a similar manner to a fixed-undercarriage aircraft I was working on which kept sinking on landing as if there was no gear. After a lot of testing, I found that the sim's inbuilt Aircraft Editor, if used at all, was automatically overwriting the 0.0 in extension and retraction times with a default value of 3 seconds and that was enough to convince the sim that the gear was retractable, so once you got above a certain speed it would either retract or fail (still not sure which).
This sim is still throwing up anomalies!

@peto-toobe Try this simple modification to the flight_model.cfg file...
[CONTACT_POINTS]
min_castering_angle = 0 ;0.05236 ; Defines the minimum angle a free castering wheel can take (in radians).
max_castering_angle = 0 ;3.14159265358979 ; Defines the maximum angle a free castering wheel can take (in radians).@retiredman93231 I guess this setting helps. I was able to takeoff without lurching with crosswinds at 17 kts 90 degrees from the left and from the right, although there was more a tendency to weathervane into the wind when the cross wind was from the right. I even tried 30 knot crosswinds and it really didn't feel much different than 17. In real life that would have been a harrowing experience
I was hoping that improvements to adverse yaw modeling might help better simulate the effects of aileron deflection during the takeoff rolls, but unlike real life, aileron deflection doesn't seem to have much impact on countering weathervaning during takeoff with a crosswind in this or prior versions of MSFS.

@berniev Sorry if this has been discussed to death, but is this weathervaning issue a planned feature (for some sort of accuracy of flight model reason) or is it a bug with the way the JF Arrows interact with the ground in MSFS? Either way, it makes my most favorite plane pretty much not usable. Ive tried all the things (except hacking the config file above), using 5 degrees of rudder trim counter to the cross, using only 30 manifold pressure in takeoff, with mixed results. If this is not something JF intended, I really wish they would fix this.
-
@retiredman93231 I'll have to give that a try. Thanks for the tip. It is probably worth noting that the Arrow's front wheel is not free casting.

Still having tremendous issues when taking off with crosswind. Currently its unflyable with this bug.

I also have this issue. Are we waiting for an update since SU5, or was it like this before that update as well?
I'' try the values suggested by @RetiredMan93231 , but feels odd to be needing to change config files in order to perform a normal takeoff.... -

@theissondergaard Have you been in touch with JF support?

@gabe777 The forums are more for us users to ask questions to each other and share stuff. But if you contact support an actual ticket is created so they can track it. I don't think all the developers even look at the forums.
As someone who works in software development, if there's no ticket for something it's probably not getting done, because you'll just forget.

@vcapra1
... I've heard this argument before. Problem is, no-one gets the benefit of the solution... should there be one.
People never go to FAQ pages. We like forums.
Unless the problem is specific to all users, then posting up any 'solution' is of marginal benefit at best and quite dangerous at worst. This thread is a perfect example - the first post here was from August and if every user needed to change the cfg files in order to take off, we would have had some pretty damning reviews by now.
The point of the forum is not for support.

@derek Yes I take your point.
I will fill out a support ticket when I have an hour to spare, given it wants so much information.

That's the idea. Hopefully, with so much stuff to fill in, angry punters will just give up and go away. We spent ages coming up with lots of pointless fields to waste users' time. Sounds like it paid off

Don't know if you're being sarcy but it also puts people off buying stuff too.
This "hidden" support system is not very popular.
@gabe777 It doesn't take an hour to fill out. A few minutes tops. And it's not hidden, there's a link at the top of the homepage and it is the one and only link in the "Technical Support" section of the manual.
The small amount of additional time it takes you to create a support ticket probably saves the devs hours that they would otherwise have to spend combing through the forums separating general discussion from bug reports.

Really? On the contrary, I think Just Flight's Support Ticket system works well and it only takes a few minutes. The support they provide is one of the reasons I buy their products.
What BernieV suggested works nicely for me.
