I was under the impression it was functional I guess when I bought it. My friend and I tried playing today for the first time and switching control would cause us to randomly fly up in the air and whatnot. You could even control the plane with it not running (not even the electrical systems on). After we finally got flying somewhat properly, nothing in the rear cockpit worked. All I got were random readings in gauges (if they worked at all), tons of random warning lights, the cockpit looked liked it was open from the inside, but closed like it should have been from the external views. The power cut in and out randomly. It made no sense at all. Thoughts? We tried a ton of times to get it to work to no avail.
