The A2A Simulations Community

I purchased the A2A Piper Cub w/Accusim in late April, and the package ran fine on my old system. But on my new system, Accusim is not working correctly.

Without Accusim, my A2A Cub will take off as it should from a runway. It will begin to yaw to the left and I have to correct with the right rudder just like I'm supposed to.

With Accusim, my A2A Cub does not take off correctly. Instead the Cub will not only yaw to the left but bank excessively to the left to the point where if I only correct with right rudder, the aircraft slips to the left off the runway with the right tire up in the air and the left wing skimming the grass. I have tried reinstalling the entire package, update, and hotfix, but this has not solved the problem.

My new system is running Win-7 64b the Intel i7-3770k and two GTX 670s in SLI as opposed to the Quad Core Q9550 and a single GTX 560 Ti in my old system, which also was on Win-7 64b

I also have been experiencing CTDs and black screens intermittently with FSX, generally when I escape out of a flight or change menus, but I am not sure if this is related or not.

Hello,

if experiencing general fsx instability its best to torubleshoot and get FSX working before troubleshooting other issues. In this case maybe a reinstall or repair of FSX is required?

Did you installed your FSX to program files or to a different area? The instability on a new system is not uncommon but I would ask if you have any other 3d intensive games you can test to see if the instability is a system error or software specific to FSX.

thanks,
Lewis

Okay, I decided to wipe the system and perform a clean install of FSX. I also installed DirectX End-User Runtime Web Installer just incase there was something missing in DirectX 11 that FSX didn't like. It's too early to know if the fatal errors have been removed, but I will let you know shortly. Also, I installed FSX to the default program files directory. I have tested the system with 3DMark 11, and the computer performed well. Other than that, I have no intensive games to test the system with.

Now with FSX running smoothly, I am still have troubles specific to only the A2A Piper Cub. I can't duplicate the problems with other aircraft. This again has to do with highly excessive overbanking to the left. For some reason, this is most and always prominent when taking off at KHQM (wind is at 0 knots) and always does the overbanks to the left no matter which direction out of the airport I take off in. Even with realism settings to easy, the aircraft does it. When I turn Accu-Sim off, the airplane does not do it. At most airports, I don't experience this at all or at the least is barely noticeable.

Okie dokie,

can you please make sure the realism settings are set as stated at the beginning of the manual. Setting the realism sliders to anything but 100% real may result in weird affects. Its also really starneg that its happening at one airport, which suggest it isnt he aircraft itself but something else? Could your default flight/saved flight be corrupt somewhat in the weather area? (I dont think default flights are removed with a normal fsx uninstall and must be manually removed/deleted)

The realism settings are set as the manual requires. I will also emphasize that it does happen at different airports but not to the extent that it happens at Bowerman. I have tried taking off in the opposite direction out of that airport, and my plane always banks to the left (so I wouldn't think that it would be a weather issue but I am just guessing). I did a complete wipe on my computer and still see the issue arise, but only when Accusim is enabled and only on this one aircraft, no other. Is there a chance that my Accusim add-on is corrupted?

Does this occur on all versions of the J-3...tundra, floats, etc?

It is possible that something is corrupt in your Accu-Sim download and the code
that detects the surface type and modifies drag based on the surface type and model
is getting bad inputs.

I would re-download the Accu-Sim package for the J-3 just to rule out that possibility.

If a new download is needed on the A2A Store give me a shout with your order number or email address so I can get your account andactivate the downlods for you.

thanks,

Hi Lewis,

I got a little further with the problem. It appears to be a compatibility issue with Orbx scenery. I tried another fresh install without Orbx, and the plane flew just fine at KHQM. Immediately after installing Orbx, the plane excessively banked and slipped off the runway.

I am asking the guys over at Orbx if they have experienced this problem before as I'm sure a lot of them fly the A2A Piper Cub. Perhaps it will help narrow down whether it is truly a compatibility issue or if one of the downloads are corrupted. It may be worth trying to install a new download to see if that resolves the issue. My order number is 69165 if you think it's a good idea to try.

I have just about all of the Orbx scenery software and I don't have the problem that you have in the piper cub. I know you didn't want to here that
It may be just one of the airports that is causing the problem here's hoping

Norforce, thanks for the reply. I got a reply at the Orbx forums and it turns out that one of them tested it and experienced the same problem.

Not really sure where to move forward from here.

Interesting last post about the wheel being stuck in the tarmac on loading. Could this be it?

thanks,
Lewis

Lewis, I don't think so. Here is an image of what I am experiencing without the wheel getting stuck in the tarmac.

Hell blackbird,

does this happen in the default cub if you where to load it after it happening with the A2A Cub?

thanks,
Lewis
