I need a P-47 machine gun light circuit
I recently bought a used FMS 1700mm P-47. The thing is huge!
The P-47 has 4 50 cal guns on each wing, I don't know if they fire randomly or in a sequence if you compare them to each other in the wing.
My plane has a dim orange light in each gun that stays on steady.
I would like to build a circuit board for each wing that would flash much brighter LEDs in the gun tubes.
Question 1, do they fire random or in a sequence?
Question 2, if sequence, do they fire from inside to out or outside to in?
Question 3, anyone have a suitable 4 light circuit?
I will put the board in each wing then run power through a RC controlled switch.

I just watched a video of a P-47 gun test. The guns fire so fast that it is impossible to tell if there is a pattern or not, so I am not going to worry about that part any more. I'll just set them up to flash very fast. But I want them bright enough to be seen. The current lights can only be seen while you are holding the plane.

Do you think this might help you? https://hobbyking.com/en_us/catalogs...&q=machine+gun

I have it in a bird that is in a multi year finishing queue. I made gun barrels from aluminum tube and drilled "ventilation" holes. You can see the red "firing" pretty well even in daylight in the house..
The sound module isn't that bad either for the dirt cheap price. I removed everything after initial setup to cover the wing. I haven't put it all back together yet or I'd shoot video for you.

I suppose it would but it would take 4 of them.
Might be the simplest way to go though.
Not sure about the little speaker, it would be working pretty hard to be heard over this thing.

Way back when I did the initial setup I was pretty happy with the LED's. After moving the speaker to different areas of the fuse I could get decent gun sound. Probably wouldn't be super loud at a long distance though. My plane is covered balsa so it kind of attenuates the speaker. Your foam bird is probably going to be hard to get good sound from. I would think It acts more as a sound insulator.

I don't think I will worry about the sound system.
