Very finicky of a plane/ship/blimp thingy. I built this a very long time ago and one of two airships I've made, the other being much larger but not nearly as controlable as this one but that'll be explained with that ones description. I don't remember much for the controls but flying it around for a minute to make sure it even flew showed me that roll didn't do anything that I noticed if I even have roll, pitch is strong, yaw is main way of flying it. If it begins to flip out kill the throttle and it should fix itself most of the time. Needs a major redesign but I don't have nearly enough time to rebuild or atleast fix however many things are wrong with this airship. Even with all the flaws I hope you atleast get some enjoyment out of it. Good Luck!
