In late December of 2024, I built a missile without any gyro or guidance from the missile just the missile powering it. Obviously this wasn't exactly a walk in the park, I had to build huge wings and scale them down which made the lift drastically huge for a small missile.
I also resorted to asking for help with the guidance system from a pretty famous missile builder in SP. The missile is gonna be able to top-attack and direct-attack onto the target which I had in mind. The coding and the designing aren't the worst part. The worst thing is the missile will go crazy if I make the launcher "lightweight". It will only work if I make the launcher 1.5 tonnes or heavier and speed over 150m/s will also make it go crazy. The most absolutely diabolical thing was if I changed the connection of the "ballast weight" to other fuselage parts it would also go crazy. This wasn't a big problem until now when I changed the launcher platform.
