Unfinished Crazybird Concept B-4A Lightning

its weight distribution my friend, I suggest you press they eye icon and then tap the red, blue and yellow buttons, red is Center of Mass, blue is Center of lift and Yellow is Center of Thrust, it reminds me of an aircraft prototype that was drawn up for the AmerikaBomber project, mainly the engine placement on the aircraft

@Livingg017 ok

what is the problem so? it loops on takeoff? is it uncontrollable? i usually tend to build a lot of experimental airframes so i know how to fix that issues, if you want me to

@Livingg017 I actually tried a vertical stabilizer but it didn’t work

@Crazyman552588 i suggest adding a vertical tail section

@Crazyman552588 the craft does not have vertical stabilizers and so it tends to “drift” because it does not feature a system that prevents that. For example, the YB-49 (real plane) which is quite similar to this one, was developed when fly-by-wire didn’t exist. It had small vertical stabilizers that decreased the yaw drift a lot but it still did want to enter a flat spin. Check this video from minute 18 on and you will notice how unstable are flying wings by nature https://www.youtube.com/watch?v=eG4E55Havyc

@Livingg017 wdym

@Crazyman552588 the game phisics are not prepared for flying wings, on my AA UXF-1 Ghostknife craft you can see small vertical surfaces on the wing tips, which solved the strange unwanted drifts on the plane. Try adding some tail or tip vertical surfaces

Now that I think about it I will try to figure out why it keeps flipping over

If ur talking about this plane, it would be the best plane if it didn’t keep flipping. Like for some reason the plane wouldn’t move. But when I set speed to 100 m/s, it will flip over!

@NicholasZhou what? This plane??

Supersonic capable Flying wing design. Probably your best craft.
