The x-line is a strange expiremental aircraft that I've been expirementing with for a couple of days, it is interesting for its unfolding wings, it has a strange speed envelope and flies nicely at 20% throttle and flies very slow, it can also glide for a long time giving it a very efficient characteristic. I think this would be good for high altitude and long range flights because of its huge wingspan the reason this thing is expiremental is because of the utilization of the wings for vertical stabilization and lift. I know that was alot to read but this thing needs a lot of explanation. ty. Bestplanes101 controls: flies like a regular plane but a little different once you take off put the vtol up for transition to x, while transitioning it may force the nose to rise but make sure you have control to stop that. when you want to make a turn make sure to use the rudder this is one of those planes that uses the rudder a little to turn
