J-50(V3.1)

Hi, this is hash257. After two weeks, I've made some further optimizations to the previous J50. This time, I improved the flight control system to make flying more stable and comfortable. I also equipped the aircraft with a fire-control radar and added four PL-15 air-to-air missiles to the weapons bay, inspired by the work of @OSxiaoheng. Additionally, I strengthened the wings, so they are less prone to breaking than before. The tail nozzle has also been redesigned to be more realistic. There are even more optimizations, but I can’t list them all here—wait for you to discover them~

Introduction to Action Groups
Please take a moment to understand the action groups carefully. Otherwise, you might not be able to fly this thing properly.

Action Groups 1–3: Radar and Missile Related

· (Action Group 1) RADAR: This is the radar. It is turned off by default. When you activate the fire-control radar, it will automatically scan all crafts within an 85° cone in front of you (with a distance limit, keeping it realistic—it won’t detect objects outside the atmosphere). Finally, it will lock onto the closest target.
· (Action Group 2) Switch Locked Target: Used together with the radar, it switches the locked target to the next closest target. (If there are multiple crafts with the same name, the lock might switch as described, but the displayed target may not update correctly.)
· (Action Group 3) Fire ATAM: Launch air-to-air missiles! Of course, you need to have a target locked and be within the required distance, among other conditions.

Action Groups 4–6: Flight Control Related

· (Action Group 4) Assist Fly Control: This is essential for the J50. If you want to experience pure flying fun, turn it off—but be aware that the aircraft will be much more prone to losing control. (Note: Due to the aerodynamic effects of the missiles on the wings, the flight control assistance is partially disabled until all four missiles are launched. Otherwise, it may cause oscillation and instability. To experience the full flight control system, you need to launch all four missiles first.)
· (Action Group 5) Speed Limited: This restricts your throttle based on speed, ensuring your flight speed remains below Mach 1.7. This is the speed range where I conducted extensive testing, and the flight control performs stably. I haven’t tested much at higher speeds, so it’s easier to lose control. If you want to fly without speed restrictions, turn this off.
· (Action Group 6) Switching Fly Mode: Switch between three flight modes:
1. Normal Mode: The default mode.
2. Stealth Mode: Locks the wingtips, reduces maneuverability, and decreases radar cross-section (let’s assume it has this feature).
3. Combat Mode: Removes wingtip angle restrictions and disables wing angle safety checks, allowing for supermaneuvers. However, in this mode, the wings are much more likely to break—use with caution!

Action Groups 7–8: Miscellaneous (Less Important)

· (Action Group 7) Light: Turns on the lights on both wings.
· (Action Group 8) Landing Gear (Auto): Automatic landing gear. You don’t need to worry about it—it will deploy or retract based on speed and altitude.

Finally, wish everyone happy flying 😊. If you have any questions, feel free to leave them in the comments. I’ll continue to optimize this before the final version is settled.

嗨，这里是hash257。时隔两周，我又对之前的J50进行了优化。这次我改进了飞控系统，让飞行更稳定、更舒适。我还为飞机加装了火控雷达，并且在弹仓中添加了四枚PL-15空空导弹，灵感来自@OSxiaoheng的作品。此外，我增强了机翼强度，现在机翼不像以前那么容易断裂了。尾部喷口也重新设计，现在更贴合实际。还有更多优化，这里写不下，等你来发现~

活动组介绍
关于活动组，请仔细了解，否则你可能无法正常飞行。

活动组1-3：雷达和导弹相关

· （活动组1）雷达：默认关闭。打开火控雷达后，它会自动扫描前方85°角内的所有飞行器（有距离限制，贴合实际，不会检索大气层外的目标），最后会选择最近的目标锁定。
· （活动组2）切换锁定目标：配合雷达使用，切换到次近的目标（如果有很多同名飞行器，锁定可能会切换，但显示可能不准确）。
· （活动组3）发射空空导弹：发射导弹！但需要有锁定目标，且满足距离限制等条件。

活动组4-6：飞控相关

· （活动组4）辅助飞控：这对J50是必须的。如果想体验纯粹飞行乐趣，可以关闭，但飞机会更容易失控（注意：由于导弹对机翼气动的影响，在4枚导弹发射完之前，部分飞控效果是关闭的，否则会出现扰动问题！想体验完整飞控需先发射完导弹）。
· （活动组5）速度限制：根据速度限制节流阀，确保飞行速度＜1.7马赫。这是经过大量测试的稳定范围，更高速度测试较少，容易失控。想要无限制飞行请关闭。
· （活动组6）切换飞行模式：三种模式：
1. 普通模式：默认模式
2. 隐身模式：锁定翼尖，降低机动性，减少雷达反射（假设有效）
3. 战斗模式：解除翼尖限制，允许超机动，但机翼极易折断，请谨慎使用！

活动组7-8：杂项（不重要）

· （活动组7）灯光：打开机翼两侧的灯
· （活动组8）起落架（自动）：根据速度和离地距离自动判断，无需手动操作

最后，祝大家飞行愉快😊。有任何问题欢迎在评论区提出，我在最终定稿前还会继续优化。
