This is a quick video of an airhorn (4 horns) that I installed on my MCS. It is powered by a 9oz paintball CO2 cartrige with a regulator from Kobalt (Lowe's Hardware) inside the black box. The valve is triggered by an aircraft Bowden cable with a T-handle pull that is just to the right of the handbrake.
