I have installed LEDs into the Vickers guns to simulate the muzzle flash. It works great!!! From the side, the LED reflects inside the black barrel, and from the front, WOW, the LED looks like gun fire even in my bright shop!! I can't wait to see and hear this in the air. It was worth the two hours it took to fish the LEDs into the guns.

I will soon post the firewall cutout for the battery installation, and show how I got the sound system and electronics all stuffed into the cowl.
