Remember this is totally user definable. It will come pre loaded with your choice, but you can load any sound set in it you want.

For airsoft you would have to add a contact switch on the gun, and wire the sound trigger circuit to that. I will include instructions on how to do that. I haven't bought an airsoft tank in a long time , but someone told me they now have a contact switch built into them. If this is true then it would be really easy, but would require some soldering, I think. I might have to buy a new airsoft tank and check it out. Perhaps HL brings some wiring back to the RX 18 from that contact switch already.

If anyone has an newer HL airsoft tank, I wouldn't mind hearing if there is a contact switch on the gun and where it ties into the HL electronics.
