The A2A Simulations Community

Hi all, a few months ago I purchased an aircraft for use in FSX SE, I will not post the company name here, but will name it in a PM if anyone on this forum feels they may know of a solution to my problem. The system requirements required either FSX with SP1 or Accelleration. If I understand correctly, FSX SE meets those requirements. The continuing issue I encounter is the aircrafts reaction to control input, namely the rudder. I have been communicating with support to attempt to remedy the situation, but we are not in front of the problem. I have been told this, “when it comes to steering, and in fact there are only limited options when choosing code variables and contact point settings.” I’m not sure I understand this comment. Although different coding systems may or could be used by different companies, it would seem to be reasonable to assume that coding or contact points are sim platform specific in what would be required. Perhaps my assumption is totally wrong, I know nothing about coding or contact points. What really confuses me is that A2A has provided the same aircraft to its customers and it does not exhibit any of the issues I am experiencing with the other company’s version. I just find it very odd and frustrating, especially when this company charges a price comparable to what one would expect to pay for a study level aircraft, even though it’s not advertised as such. So, if anyone out there would care to know more I would give more info in a PM regarding the company and aircraft. I’m only looking for a solution and not a means to attack another developer or bash them in any way. I simply would notify them that the issue no longer is a problem. If this is all the further I can take this here, then thanks much for allowing me to vent.

You havnt really told the issue at hand, if you let the community know the issue it might be a common issue easy enough to fix.

If it's an A2A aircraft you are having problems with, then you are quite entitled to seek advice about it here, on these forums. If it's not and more of a general siming thing then answers will vary, depending on how technical it is.

Steve.

What is the aircraft? Maybe others are having the same problems.

If this is an Aerosoft product, if the purchase page does not specify FSX:SE compatibility then it will not run on FSX:SE. They say this information is in red text on their site but I have been unable to find it.

Some other vendors may be similar.

Well here’s the issue, Flight Replica Super Cub Ultra. My problem is the tail wheeled aircrafts, floats......no issues. When I try to taxi, adding power in small increments, and use the rudder to turn left or right, centering the rudder after the turn starts, and of course adjusting power as well, the plane just continues the turn in the direction that was initiated. The only thing I can do is use opposite rudder and differential braking, along with some added power to get it to stop turning. But then it just keeps turning in the direction of the correction. Actually, to taxi, I have to use power and differential braking to get anywhere and just leave the rudder alone.

I’ve been going through support with them and they are trying, but after several uninstalls and reinstalls and even being sent a new software install package, no joy. My computer meets their necessary requirements too. I have CH Yoke and Pedals, using Windows 10 and FSX SE.

I’m not having problems with my A2A 172, 182, Piper J3 or Comanche. Milviz Beaver works fine too. So I don’t know what to think here.

The reason I initially left this detail out was I didn’t want it to sound like I was bashing another developer. That’s why I stated I would be glad to do a PM. Just seeing if I can get this sorted out. Any help would be appreciated. Thanks for the replies.

Go into the aircraft.cfg for the airplane (use a Text or Word editor). Find the section that says "[CONTACT_POINTS]"

Copy that section here in full.

Hey CapFlyer, how's it going. Here is the info you asked for:


[contact_points]
point.0=1, -15.71, 0.0, -0.89, 1800, 0, 0.256, 180.0, 0.03, 1.5, 1.2, 0.0, 0.0, 0.0, 0.0, 0.0
point.1=1, 0.96, -2.95, -5.04, 1600, 1, 2.20, 0.0, 0.15, 2.5, 0.58, 0.0, 0.0, 2.0, 0.0, 0.0

As I suspected.

The number in bold is the "pivot angle" for the tailwheel. When set to 180, FSX/P3D takes that to mean that it is a free castoring tailwheel. As such, the only way to steer it is with differential braking and power plus what limited rudder authority you get.

If you want to get direct steering, change that value to 90. It'll still give you significant steering angle, but it'll "engage" the direct steering capability. The only way to allow for the real semi-locked tailwheel to function correctly is through a gauge, and I guess they didn't design one to give the functionality.

Thanks a bunch CAPFlyer, I truly appreciate this. I’ll make the change.

I suggest something less than 90. I've tried 90 degree tailwheels and it can cause problems, especially trying to start moving when the rudder is at full lock.

Try 75 or so which will give you a very small turning radius.

I usually use 40 or 60.

Steve.

If my trig is correct then setting it to 80 would allow the plane to pivot around one of the front tires. I've found this kind of setting is usually too much to get the plane moving easily from a standing start with the rudder pedals fully deflected. I suspect 75 is too much as well. Setting it to 60 is probably about right, but try a few and see what you prefer.

My usual problem is finding a setting that allows the plane to start moving easily but gives a reasonably small turning radius. The plane I'm flying now needs the rudder centered to start moving, but doesn't have as small a turning radius as I would prefer, even using differential brakes.

The Goose and DC-3 are 79 and 72 approximately, but you can use differential engine power on the twin engines to get the plane to pivot on one wheel.

I find 60 for the Flight Replica Super Cub Ultra is about right for me. Turns on the ground pretty quick. In P3D v4 too.

The change in the contact point did the trick CAPFlyer, thanks again, I appreciate the help. And thanks to all that replied, 60 worked the best for me also. Back to flying again! This is such a great forum!
