Upgrade dll errors...

[bob_nj]

I tried to go from 3.5 to 4.5
3.5 ran fine, but I'm now getting the error;

Cannot find import; DLL may be missing, corrupt, or wrong version.
File fmod.dll error 126
This is the error when I try to run from the application file.

When I use the launcher, I get a similar message with this file listed;
NLVSCAN2.dll error 126

Running XP Media Edition sp3 on a laptop

Any ideas?

Thanks
Bob

Upgrade from 3.5 to 4.5? Do tell, how are you trying to accomplish this? It can't be done! If you mean you bought G4, then update it via the launcher before you run RF. Sounds like you may have an Intel video chipset in your laptop.

[bob_nj]

I was running 3.5

Thought I could uprgrade from the site to the new version

What are my options now?
The G3 folders are still showing in explorer.

So 3.5 is as far as I can go.
Originally bought 3.0

Thanks

[jeffpn]

You probably need to uninstall (if you can), wipe out all RF folders, and reinstall 3.0. Then upgrade via the launcher to 3.5. 4.5 is not possible unless you purchase it.

[bob_nj]

I guess I can't just uninstall 4.5 as it only "RealFlight G3 R/C Simulator" and RealFlight simulator as options in the Add/Remove program.

3.5 still loads and runs, so I'm going to leave it for now as I don't want to
deal with the process of reloading right now.

Thanks so much for your help though.

One of the real reasons I wanted to upgrade was the fact the all of the planes
I use fly good upright, but as soon as I go inverted they dive for the ground.

I've messed with calibration and CG, but can't figure it out.

Thanks again

YES 3.5 is as far as you can go!
If you want 4.5 you must either buy 4.0 and get the free upgrade to 4.5
OR buy 4.5
as far as flying inverted:
remember that when inverted your elevator is upside down so.... up is down ...and down is up
In the aircraft editor you can also change the main wing airfoils to a more symetrical wing.
and this will improve inverted flight characteristics on many planes..as well as 3d perfomance

[wjkssmd]

There are MANY airplanes that are incapable of flying both inverted and upright without pushing the elevator control due to the inherent design. If you want a plane with that dual capability, you should look for a pattern type/style aircraft. Even then you will likely have to push a tiny bit on the inverted pass. The more symmetrical the plane is about the horizontal axis, the less elevator is required.

You should also recalibrate the controller and make sure the plane flys with as little trim as possible. It is not hard to move the CG using the airplane editor (G4.x anyway). I cannot speak to your version.

WHAT planes are you using???
I added " RC symetrical aerobatic airfoils" in the etitor
to the stock P-51 and it fly's inverted like a champ!!

[bob_nj]

The plane I'm currently using is an aerobatic 3D Yak.
The airfoil listed is an NACA 0014.
How can I add the airfoil you listed?

As I said, I've tried the calilbration, and the CG, but there's just something I'm
missing.
The real culprit I suppose is that it takes so much up trim to fly level, that
inverted the planes just take a dive.

It's with every plane in the program, so I'm thinking changine one may be
a fix, but not the answer.

I may just have to live with it.
It is annoying though.
I use the sim for practice, and it makes things like slow and point rolls
use an inordinate amount of stick to look right.
My brain likes practice, and I try to keep it as real as possible.
This makes it unreal.

I just thought someone else may have had a similar experience and could
offer some advice.

Thanks for the replies.

The current version of the Yak54 uses the NACA 0014 airfoil... On my sim, it requires a touch of push (down) to fly inverted. The amount of push is about 1/16". I consider that normal and expected behavior. The yak is not a pattern plane. I do not expect it to fly arrow straight lines. It is not designed as such. I guess that the question is how fast is the decent rate on your version? How much stick do you need to fly inverted level?

I don't think changing the airfoil is an answer... if you change the airfoil, it is no longer the plane you think you are flying. I don't think that it is possible to add 4.5 airfoils to 3.5. I think you are limited to what you have. The plane is modeled to fly like the real thing. If you don't like the flying characteristics of a particular plane... select another. Of course, do what ever you think. Sometimes it is the pilots skill level.

[bob_nj]

I understand all that.
I've been flying R/C since 1976.

I've stated several times before that it happens with ALL the planes I try!

[jeffpn]

Are you saying that IRL you give no up elevator to fly any plane inverted? I find the sim to be quite accurate with the up elevator for inverted flight. I've never thought about trimming the plane while inverted, due to the fact that the plane will climb too much when upright. I guess I've never seen anyone else complaining about the problem you're describing.

[bob_nj]

By "up" elevator I'm guessing you mean pushing down/forward on the stick?
Yes, there is a certain amount of "push" in real life.

Again, as I mentioned above, in the sim, it's an inordinate amount in comparison to what it should be.

Thanks
Bob

[jeffpn]

Yeah, sorry, I did it again. When I said up elevator, I meant pushing up or forward on the stick. I was rereading your posts to see if you ever put a value on how much stick movement you require to hold level flight while inverted. I didn't see a concrete figure, only the word 'inordinate' and 'certain amount'. As a percentage or a fraction, how much DOWN ( ) elevator are you giving on all of your aircraft to fly inverted level? And I believe jbourke recently posted where the RF planes starting trims are set. Frankly, I don't mess with the trims. But if you do, I don't think you should trim it for upright level flight at full speed. Trim it for a slower speed. That should help.

[wjkssmd]

I did not know how much stick time you have... sorry to offend you... you never know who you are dealing with here. How much do you move the top of the stick? Give us an idea of how much...

It could well be that there is something wrong with the controller... You might try borrowing the controller from another guy... it would have to be a G3.5 box. You can also talk to the guys at the technical support. I'm outta here.
