Hello,
I just did a update for the Boeing 747-400 that came withFS2004 and now my when i hit the landing gear key the wheels won't come down?
Here is whats in the readme file

Boeing 747-400 Flight Dynamics

by Pedro Oliveira

8-21-2003

The standard Boeing 747-400 that comes with original FS2004 is not accurate; its engines develop too much thrust while being too weak at idle, and the cruise settings are incorrect.


After a few hours tuning, it now features accurate:

- Vmo and Mmo;
- Cruise Speed of Mach 0.855 / FL360 / 22,000lbs fuel burn / 91.5% N1 at 640,000lbs gross weight;
- General Electric CF6-80C2B5F rated at exact 62,100lbs delivered at 100% N1 (ISA-SL, at takeoff);
- Spoilers negative lift;
- Brakes power;
- Fuel burn;
- taxi thrust.

is their away to fix this or go back to original? Thanks

Hmm, as a general rule you should always back up a file before doing an overhaul like that.

Determine what files were overwritten by the update. Im guessing the aircraft.cfg and Boeing747-400.air files. To revert to the original files..........

All aircraft are located on CD1\ MSGAME1.cab.

Open the .cab file, click on the 'path' column header to organize the files by aircraft. Scroll down/up to the b747-400 files and drag the needed files into the appropriate folder(s) in FS9.

Cheers,
Dave

If you can't find em ......I or somebody could email them...if you "unhide " your address for a while....

Commoner........

Don't panic - yet  ;)

Just take copy of your [contact_points] section in the aircraft.cfg file and post it here.

If you don't know how, open up aircraft.cfg in Notepad, scroll down until you find the section, place your cursor above it, hold your left mouse button down and drag until you are below the section. Release the mouse button. This will select and highlight the right bit.

Hit CTRL-C (to copy to clipboard)

Come back to the forum, start a reply, place your cursor in the text panel and hit CTRL-V

Post it and we'll be able to spot the problem quite easily hopefully.

ok hope this is the right code you need?

OK I posted reply a few ago and I was just thinking let me check something for the Boeing planes and its all 3 that I have in there when i take off the wheels come up when i hit the my button and i see the arm go up aswell in cockpit so I did it a few times and they won't come back down I tested all 3 and the samething. Although right when i lifted off they went up and came down so i flew abit longer and tried to bring them down and they didn't. here are the aircraft
777-300
747-400
737-400
those are they default ones that  came with FS2004 but i did the upgrade for the 747-400 and thats when it messed up I tried opening up the CD-1 and look but was lost in finding the aircraft I unhiden my email if someone would be nice to send the original ones or have a link to where I can download them. Thanks

I unhiden my email if someone would be nice to send the original ones or have a link to where I can download them. Thanks

OK GH...sent the aircraft CFG and the 747 400 Air file....hope you can make good use of them....any others you fancy, just post or reply to the Email.

Are you sure you haven't got a failure happening.

Sounds like it to me in which case new cfg and air file won't necessarily help unless there's a typo in the new ones that will be corrected by replacing the old.

When it happens hit Alt..aircraft...failures and see if anything shows up. Sounds like a possible electrical failure.

All fixed now thanks to commoner
for sending files i know can land with wheels and not belly land  ;D
