Outdoor skydiving simulator produced in 2012. Operated in the phoenix AZ area for 1 season. Tunnel is an open air type, 10' column of air, inflatable air cushion mat around. Tunnel prop is a 3 blade ground adjustable DC3 aluminum prop, powered by a 12 cylinder 800HP CAT 348 diesel engine. This tunnel is built as its own portable trailer. 1,000 gallon diesel fuel cell located in the front of the trailer and engine is in rear over the axles. A electric raised control cockpit is controlled by the operator and raised when tunnel is in use. Dual stairs attach to front of trailer to provide safe access with fenced upper deck to prevent anybody from falling off the ride. The safety canopy is no longer with the tunnel as it was stored separately and the trailer was stolen thus no more canopy. I have done some searching and there is company's that fabricate inflatable ones that look very nice, I think it would be an upgrade from what we had. I personally have over 24 combined hours in this tunnel. You are purchasing a used tunnel with no warranty expressed or implied and you understand that this machine requires insurance, safety training (not provided by me), and suggested that you come see this tunnel before you buy. It is currently in storage and not assembled. This machine was expensive when new, only has 1 season of operating. I took another direction in life an no longer need this machine. I have shipping contacts and I can get you a shipping quote. All I will need is your zip code. Transportation requires a 33,000 gvw or higher semi truck with air brakes. Price is 0,000.00 USD deposit of ,000.00 USD upon purchase balance due in 3 days after. Contact me before buying if you have any questions, thanks for looking
