lol old thread, but this map seems totally impossible.
its not about moving in the top of that vertical tube (What the helping board shows), but reaching the top of that vertical tube.
The plane stalls and I and i guess most people crash to the side of the tube before reaching the highest point. (usually it stalls where the 2 tube joins, it seems to be too long going up)
Is that intented or something secret is outta there.. Someone should really show how to do this finally
