Well i have done the loops and rolls (rolls left and right) and found it was starting to et a bit boring thus my flight were vut down to about 6 minuts (didnt know what to do so your just flying around burning fuel) SOOOO (mistake #1) i though i would try an outside loop. well i almost got to the apex of the loop when it did this wierd fliping roll thing that really disorentated me. Tried it a couple more times but the same thing kept happening.

What am i doing wrong?
