what u do is: get into the box any way possible. (i used a heli, but if u do make sure it doesn't fall in the box as well!) get in the J10. accelerate towards the wall. you should tilt downwards. at 20 - 35 degrees get out of the plane. when the plane falls back on its wheels it will keep on tilting and hopefully go on its back wheels. when this happens quickly get back in and accelerate over the top . it takes awhile, and even if u get it out it will likely crash, but manage it and your enemies will bow down before your mighty J10! P.S: if the J10 ends up in the corner when u accelerate it makes it much easier. (hope that made sense, sorry if it didn't)
