RC Tank Warfare community hobby forum

A few years back, Dan at Battle Armor hooked up a pair of cheap 123 soundcards to an RX18 and posted some vids on You Tube. I am wondering whether there are any UK sources for the boards, or does anyone know which boards he used, or whether there are any similar ones at the same cheap price?

Here's the source, these guys are great.

More options than you could imagine. I started with the 123 for destroyer sirens in a RC boat, but quickly moved on to programmable ones compatible with Mac OS.
