After over a year of refinement, trial and error and learning from other flight model projects, I present to you the successor to my previous FM project. Basic External Flight Model (EFM) template! This is an enhanced version of the EFM template provided by Eagle Dynamics, with emphasis on simplicity and editability while also feeling smooth and believable. This FM template was designed to work "out of the box", designed like a two-engine subsonic trainer/fighter. What is included: Lift, drag, side, and thrust forces. Axis and discrete (keyboard) pitch, roll, and yaw controls with trim. Landing gear, flaps, slats, and air brakes. Engine startup/shutdown. Basic fuel draining system. Basic damage mechanics. Semi-realistic stalling, Dutch-rolling, and other oscillations. Infinite fuel and easy flight options. Example parameter to interface with the Lua environment. Lots of comments explaining how things work. The template itself and a pre-built .dll file can be found on GitHub! https://github.com/IGServal/DCS-Basic-EFM-Template Requirements: Microsoft Visual Studio (2019 was used to create this, but other versions might work as well). Basic understanding of C++, Lua, and flight physics. Feedback, bug reports, and suggestions are always appreciated!

This Elytra Mod is an entertaining, overpowered, fun and fictional mod. It does follow some general rule of a delta wing design plane but still, it will be just a mod for fun. It’s still in development but I hope posting it on forum earlier would gather some idea. YOUTUBE LINK DISCORD LINK Requirement: FC3 / F-15C What Elytra can provide? 3D THRUST-VECTORING You could practice with the quick mission F/A-18-Ace-dogfight. An ace AI F/A-18C would pull you into an AoA fight which you could make the best use of TVC You could switch mode in FCS page to toggle Pitch/Yaw/Roll TVC separately. Sometimes you only want the Pitch TVC. In order to make the plane less UFO, the plane is made for not stable in stall. Don’t pull too hard while doing a post-stall maneuver. It takes time and practice to play with TVC. Cobra, falling leaf maneuvers are can-do with Elytra but a mistake could lead to unexpected spin like a kite out of control. THRUST TO WEIGHT RATIO This plane can accelerate vertically under 20k feets Thrust may be too strong, and need tuning. Max afterburn could pull you out of trouble usually, unless it stalls too close to the ground. Touchscreen cockpit Elytra use a touchscreen clickable cockpit I'm glad that the development of it is going well! High angle maneuver It does not have an AoA limiter as you can easily recover the plane with TVC and strong thrust. You would easily stall in turning tight as a delta wing would slow down the plane very easily and you would face too high AoA. Even without TVC it still can achieve high AoA. You would stall around 45 degree AoA Very hard to fall out of the sky as the plane usually would recover itself if you push the throttle with the nose down. Super-cruise ability You can achieve 1.25 Mach without afterburner at altitude Mach 1.25 with afterburn at sea-level Mach 2.5 with afterburner at altitude Not so useful Fly-by-wire Still tuning. You could override the FBW system at the FCS page. It would help in level flight. Model weapons compatibility 10 Hard points for missiles Superb dogfight abilit EFM flight model doesn’t mean better than SFM. It just means I can mess around with the flight model and make thrust vectoring possible. The lift and drag are calculated by component separately. If you snap a part of the wing you only lose the lift drag from the part it snapped. A fair RCS for a modern fighter Custom HSI Waypoint, airbase, markpoint could be shown on the screen. Fully HMD The HUD is integrated into HMD. Custom advanced EW You can see how far is the missile incoming EW filter (SAM, AIRBORNE, SHIP, MISSILE) 360 degree of angle sensor but still having some blind spot Check six warning Cockpit WIP Only BVR mode is using F-15C. ACM mode are implemented with custom avionics code. With the custom avionics you can now acquire air targets and ground target by the HMD. No more FC3 control. Two mode auto throttle (ATC) Damage Model I didn’t work on the damage animation. No bullet holes but the wing would malfunction if it gets hit. It would snap by parts if it’s taking too much damage. Overwing Vapour Limited A/G ability (CCRP / CCIP )! Cluster bomb, iron bomb. Guidance not available right now but laser guided weapon might work with JTAC Ripple bombing setting available. See the effect of 12 x CBU-97 ripple run below TODO: Better stall behavior Custom radio I have not yet worked on the cockpit. I prefer to build a simple cockpit showing all the mfd screen and publish it. Maybe I could seek permission to use the cockpit of an existing mod as I’m not a good 3D builder… Will work on it when I consider the flight model is acceptable. This is a one man project so don’t expect the work progress would be fast. Elytra specification: Fuel capacity: 8400kg (Internal Bay) Wing span: 13.85m Clean weight: 17530 Max takeoff weight: 37340 Performance Clean configuration Maximum speed: Mach 2.5 at altitude; Mach 1.25 at sea level G limit: +9.0/-3.0 10 Hard points Credits: 3D model base from Nestor de Buen Download would be available when the cockpit is ready.

Bonjour, je me présente. Feauxe, je suis un petit moddeur sur Dcs qui a comme projet de réalisé le grandiose Dassault MirageIV. Je viens ici pour demander un coup de pouce si certains sont assez calé dans le domaine. Le coucou a donc son modèle 3D fait par ma main, des textures et tout ce qui graphiquement sont nécessaire pour l'instant. Le problème étant que le MirageIV en question est déjà posé sur une base d'EFM. Mais voila, je suis une brèle pour codé un EFM et donc je cherche quelqu'un qui bénévolement est assez fou et attiré par mon projet pour pouvoir taffé sur un EFM et occasionnellement sur le MirageIV avec moi. Si vous souhaitez plus de renseignement sur le projet n'hésitez pas a me contacter via discord ou par Mail. Mon Mail: marais.gaby@gmail.com Mon discord: Feauxe#5990 Toutes aides est le bienvenue, Merci beaucoup ! Des photos du projet si joins.

CH47 Chinook flyable, clickable, EFM ....... etc. etc. ********************* UPDATE************************* Go to the discord channel mentioned later in this discussion to download the updated mod or here https://drive.google.com/file/d/1enWBT7gDp_Ia1iwNI1umloHw1rAM-x6W/view?usp=sharing *********************************************************

Hello Could someone give me an idea of what the flight models in DCS "look like" and how they are integrated with the DCS engine. What are the inputs and outputs? What data from DCS are accessible for mods and what data is not? Are the FMs a set of equations with different inputs and outputs? Are the FMs a set of tabulated values for each possible flight case? Are they something else? I'd very much appreciate if examples could be provided either as screenshots, formulas or code. All answers are very much appreciated!

Bell UH-1M (Huey Hog) Helicopter gunship ..... flyable, clcikable, standalone, startup procedure, EFM, fully armed..... etc etc.... Vietcong added to the infantry list in Mission Editor.... for the Vietnam War. CREDITS : see credit text in folder (Cockpit by Yakarov) This is a Hi-res cockpit of the Bell UH-1M, with a simpler startup. It is not my intention to replace the UH-1H module by Belsimtek or replicate it in anyway; however there was a perceived desire in the modding community for a fully fledged Vietnam War era helicopter gunship; and so I did the UH1C, then realised that infact the UH1M was a better configuration and carried more weapons......so..... here we have the Bell UH-1M. Startup : look in folder for "UH-1M startup procedure.txt"....... there is a switch to turn on/off hints.... If you want a HiRes cockpit with all the bells and whistles working, please consider buying the UH-1H Huey by Belsimtek, that is an excellent module and gives you the full immersion experience. This project (UH-1M) was drawn together and completed by Freddy.

Hello guys, I'm currently working on a educational EFM (mainly to understand how DCS communicate with my c++ code) and so far, things are going well. I've seen in a Razbam's harrier video somewhere on youtube some green lines comming out of the plane, whose I think are the forces vectors representation for debuging purpose. Only function I see in the EFM API which would do that trick seems to be : ed_fm_enable_debug_info(); Also after analyzing Cpt Smiley F16 educational code, I found quite strange to not use any of the add_global_force or add_global_moment, only local force, which are applyied to the center of gravity. I'm not a huge fan of lift beeing applyied to the CG, since it's should be applyied to the center of pressure which is differrent. Well anyway that's another story. If you have any information about the use of ed_fm_enable_debug_info() and the difference between local and global forces, this would be of a great help! Thanks in advance! Ekoj.
