Pylons and Ordnance

Carnage, In most cases the pylon is a separate entity from the aircraft. That is, it will have it's own serial number. if it does (check photo's) then from time to time it will be removed for servicing, which could include a repaint. Some aircraft have permanently attached pylons, in which case the colour probably would be the same as the aircraft.
I've found that the ordnance is better fixed on with a short length of wire.
Drill into the pylon & bomb or whatever, and superglue thin wire into the holes to get a good permanent joint. It means you have to be accurate when drilling to get things lined up, but the bombs won't fall off with handling or over time.

I tried to fix the ordnance to the pylon which was already glued to the model before painting, But I find it hard to fix it in proper position. Anyway, Thanks.Hey, Orion How should I make those red tags??

I've done it both ways. One thing that you should do first is to check the fit beteewn the pylon and the wing surface. Be sure there is no gap. Now, depending on whether the pylons are the same color or a different color will determine when you put them on. Some aircraft have different color undersurfaces than the pylons. If you want to really add realism, rig your bomb fuses with fuse wires. Drill small holes in the fore and aft fuses and run the wire up and into the bottom of the bomb racks. Next make small red "remove before flight" flags that go into the side of the pylon. Makes a world of difference. Having been an Aviation Ordnanceman in the Navy, I have humped my share of things that go bang!

I attach them BEFORE painting, without ordnance, UNLESS a decal has to go in the same place. Only decals will keep me from attaching the pylons before painting. Makes it a lot easier to glue the suckers on, without having to scrape paint away from the glue points.

bob3242, you are right on. In some kits there can be a gap or other construction problems that need to be addressed with the pylons. Don't forget paint buildup too. But those issues aren't really a problem with ordnance.

Carnage, I've always attached the asembled pylons to the airframe after painting. That's what works for me.
