Hi. This is a pre-release of the Chinese supplement of ColdJ's Military Planes. I hope to build a J-10 in the near future but currently it is just a Kerbal knockoff of a J-20. Everything has an exact node, so no needing to adjust after attachment. It has a hinge that goes in the side missile bays that allow a missile to be swung out and even remain out if the missile bay doors are then shut. The bomb bay has 4 nodes calibrated to take the piston missile rails from my earlier plane mods.The bomb bay and side missile bays are on separate toggles. 
The internals are stock but if you have Raster Prop Monitor installed then the blank monitors will be replaced with multifunction ones.
Breaking ground is a requirement for the missile hinge to work.
This works great and is stable on stock vanilla KSP. If you have mods that change game physics, I hope it all still works but you will need to find out for yourself. If you are someone that likes the doors to snap open then there is a solution in the forum thread from a previous question for an earlier mod. I once read a Reddit comment where a poster claimed my landing gear would blow up, only for them to come back later after they realised and old mod they had was causing the problem. So please only bring up problems if you have tried it on a stock only install and have a problem.
I hope you enjoy this.
Premade with hinges but not piston rails in a folder named Craft. Just copy the .craft file to your save folder where you see other craft files you have saved.
