@Radium great work, congratulations!
-
Hello,
some news here !
-
About flight model, Topolo is hardworking to offer you the most accurate FM as possible. I received a new version today, I will conduct tests soon. Tnak you buddy !
-
I realized that Lavi fuel tank was missing. I just did one :
I tried to give it the most realistic bare metal looking.
Next weekend, I think that Lavi v1.0 will be released… @vAiCon please be ready to put it into ITO !
About cockpit, I still didn’t decided if we will make one or not, main reason being that I miss so many references, like a nice picture of the throttle for example, not talking about some explanations about cockpit setup, best pictures being these two ones :
Stay tuned !

Awesome work on the exterior, its looking great!
Very interesting how the MFD pages in the right image look very similar to those that ended up in the JF-17.
Just one small note I noticed in this video :
At points around 0:28, 1:00 and on touchdown at 1:07 shows that the Lavi has the foreplanes directed to pitch the aircraft up (trailing edge down) rather then down (trailing edge up) as I saw in your video and screenshots above.
This makes much more sense to me from an aerodynamics stand point, as drooping the entire trailing edge of the wing as a “flap” of sorts for landing would create a huge pitch down moment, the foreplanes would need to be creating lift to counteract that pitching moment.
Regardless amazing work!

Hello,
thank you for your report and relevant point, here is my answer :
The biggest issue here is that BMS doesn’t contains any specific line of code for canards.
It means that I can only do a couple of comprises, to try to get a quite realistic position of canards.
This is where the issue is : canards position depends on a lot of factor, such as flying mode, AoA, position of gears, roll, pitch and even yaw.
I am really embarrassed, because for now, I can’t represent the approach mode for canards especially because BMS doesn’t make a difference between take-off and landing…
I tried a couple of solutions, but they were irrelevant for the rest of the flight. 5% won versus 95% !
For now, as I said, I don’t have a solution. But I am still checking for one !

Understood.
I thought it might be a BMS limitation.
In which case having it correct for normal flight makes more sense.Cheers
-
the canards and TEF may use two sets of Xswitch 2 or 3, to switch the DOF directions between normal flight and takeoff/landing phase.
-
@ccc1tw hello, I am afraid it doesn’t works like that !
-
Hello,
just to let you know that I am now working on :
-
Canards movements enhancement (For now, unsuccessful to get something nice, especially on landing mode). I tried a couple of solutions, issue is mostly the interactions with the other functionalities implemented. Because I do not have any control on Gx. This is the only way to differenciate flight modes, especially because Lavi uses AFM, and is not an OFM aircraft. I guess, if it was OFM only, it would be easier.
-
Afterburner : I try to have something a little bit progressive (not too much, because it is not like that in real life), but I can’t get something good. Afterburner is an additional injection of fuel which does not changes RPM, for this reason, it’s never something that slides out of the nozzle.
-
I tried to use DOF38, but it’s totally fucked up and I can’t get a nice result. I tried by both translation and scale vectors, but it doesn’t works.
-
Also, I found that this DOF is linked with these acdata parameters :
sndAbExt 39 #External high RPM & afterburner roar - Heard mostly from the rear at close and medium distance - DO NOT CHANGE "RPM" VALUES!!! - THEY ARE NOT PURE RPM BUT FROM A FORMULA TIED TO RPM & NOZPOS CHARTS! sndAbExtChart 2 1.0000 0.00 1.0300 1.00 sndAbExtPitchChart 5 0.0000 0.80 0.7000 1.00 0.9600 1.20 0.9700 1.00 1.0000 0.90
Which is really strange (I took this example from Manos’ Mirage F1 acdata).
-
I enhanced a bit the main texture file, especially the under grey part.
-
Because nothing works well, I will do some data gathering about Griffin bomb, to help my friend vAIcon to implement it into ITO.
-
No v1.0 before next week, because I want this version to be really clean.
Stay tuned !

@Radium
Good to hear this.
Because some plane especially with the canard they use them like a brake surface after the landings.
When the nosegear touch the ground the canard turn almost totally vertical to maximise the brake area.
Or the Ailerons and flaps also move out this way.The afterburner can change to use particle system instead of textures ?
-
@repvez Hi !
Thank you for your comment. Finally, I found a way to have a progressive afterburner, and I am happy of the result ! See it in v1.0 !
Coming back to canards issues.
Regards,
Radium

Gentlemen,
I just did a little video for you to see what I did for Lavi afterburner.
For some reason, video compression doesn’t shows afterburner textures with the finest details, but it’s good enough for now. You’ll see it soon on ITO !
Hope you will like it !

@Radium
Total awesomeness,
I can see flood of requests to update AB effect on other models -
Hello,
finally, I succeeded to get more realistic canards.
There is no way it would be perfect, because I have so much limitations.
I tried my best to offer you something nice, and I think it’s rather good.
I will try to improve some stuff, but it’s really hard because it’s a matter of comprises. I already tried a lot of solutions to get something smoother, and this is the best I could have got as of today.
Hope you will like it !

@Radium Radium = No Limit !!!

@Radium looks much better! Great work! Now onto the cockpit!

Hi !
Canards’ nightmare !

Hello,
I am happy to post the first hotfix of Lavi :
1. AA missile assembly y axis was corrected and reexported + accurate parent.dat 2. Griffin bomb texture was implemented (it was forgotten in v1.0) and reexported
You can download v1.1 here :
Information : in v1.2, texture numbers will change, to match ITO architecture (vAicon will jump of joy, I bet)
Cheers,
Radium
