I would give pictures but it's kinda broken for me.

So I knew this for a while, but I kept quiet because I don't want the bug to be fixed, but I'm now feeling ok saying how to do it, so Here we go!

Step one: make a 'gun jet' by getting a mini gun and setting "damage" to 0, "spread" to 0, "bulletScale" to anything long, and "impactForce" to 5, then put it in the end of a fuselage that is at least 2.5 or 3 in length and 1.5 at both ends in hight and width, then put a fuselage cone at the front, this is what the gun will hit, or you could take the gun jet off my gun powered plane and save it as a new part.

Step two: Put a gyro on it and set it up like a plane.

Step three: Put two cameras on it, one as a aim camera (normal camera), other as a flying around camera (orbit camera)m

Step four: Put wings on it, 2 horizontal wings and 1 vertical wing is recommended, and make sure they have none of their own controls, because the gyro is gonna control it.

Step five: Make sure everything is connected and take it off the cockpit and save it as a new part.

Step six: Put it on a detacher that is connected to what you want the rocket on.

Step seven: Make sure that the gun has an armed group that is not the same as the detacher.

Step eight: Add a bomb inside, and hope the bullets don't collide with it when flying.

Step nine: save it as its own item again.

How To Start: You need to go into flying mode, press the armed group that the gun is in, hold shoot, and keep holding shoot when you turn off the armed group, once the group is turned off, feel free to stop holding, and if this works correctly, every time you press the group, it should activate automatically, and when you find out it works, use it to fly after detachment!

Sorry if that was complicated, I just didn't have enough and so my mind is all over over the place, so I hope you understand.
