I'm sorry, but the rar file that is on the OP, the craft file came up as a file short-cut. Can you fix that?

[[WIP][0.1] Red vs Blue!A BDArmory expansion pack... now with 100% more stealth!]

I tried the missiles and cannon, but they don't really work. The cannon just doesn't damage the plane and the missiles are always duds, just explodes on impact and no damage to the plane. Is that a bug?

Weird - do your log tell you that the cone was damaged by engine exhaust ?

As i told, on my install i had no such problem do you happen to have mods or

You might be experiencing the thermal bug here - one of the problems is that somehow some of the physics.cfg properties are saved in the .crafts files.

stock bugfixes installed (or modified thermal values)

Try to remove the physics.cfg files from your KSP folder, restart the game to regenerate the file, and redownload the subassembly (i reuploaded the KE-90.craft subassembly - which works in 1.04 for me (though it likes pulling Gs less than before )

No, the engine wasn't activated or the craft launched yet. I just loaded the plane into the game, and the cone just heated up on the runway and exploded.

I just temporarily fixed it by removing the cone from the engine.

As for the stock fixes, just the memory leak one from the heating system.

I realigned the engines to the back, like you said, but I have encountered another problem.

Since the engine wraps around the engine cone, the cone overheats and explodes, taking the engine with it. I don't know how to fix it.

I have a problem with the KE-90 jet engines, I can't seem to get the engines to work due to the "cannot activate when stored" error. The other engines work though, just not the KE-90.
