Despite what the name suggests, this challenge is not as bad as you would think. You are asked to combine everything you have learnt into one last course. The course incorporates knife flights, barrel rolls and inverted flying all in one and you will be in a stunt plane for this task.
There are various gates you will need to pass through that are colour-coded to whatever stunt you must perform through that gate. That being said, it is imperative you look ahead to the colour you can see for the next checkpoint so you can prepare. Stunts generally take a little time to prepare and last minute stunts generally result in death. A lot.
You start out with a couple of normal yellow checkpoints, however, after passing through the second one, perform a left knife flight because you are about to come upon a green checkpoint (green means knife flight). The checkpoint will have a direction of knife flight marked in it but you can do whichever way you prefer, though it is normally prudent to perform it the way it shows.
Remember to use the rudder to maintain altitude as you knife through the gate. Level the plane enough so there is still a slight lean to the left for the next checkpoint. Straighten up when you pass over the freeway.
You have probably noticed a blue checkpoint ahead. This means you must pass through the gate inverted. Do not try and invert by looping or you will not get there in time. Simply roll the plane to the right or left so you’re inverted and keep the plane from crashing into the ground by using the flight stick and rudders. Remember the controls are backwards when upside down! Alternatively, you can just barrel roll through the gate if you do not feel comfortable flying inverted for long periods of time.
Level up as soon as you pass through and head through the next checkpoint. Perform another knife through the following one (it doesn’t matter what direction) and pass through a couple more yellow ones. Knife to the left as you immediately pass through the second one so you can prepare for the green checkpoint ahead.
Be careful for this next bit now. Get as straight as you can on the next two checkpoints because you will be flying through narrow airspace. If you are comfortable knifing, you can perform a knife flight through the whole section and the next green checkpoint as well!
After exiting that section, you will pass through another yellow checkpoint and then another green one. Perform a right knife flight because there is a blue checkpoint ahead and to the right. Invert from the knife flight or from level to pass through the next one and perform a final knife for the next checkpoint. Level off and fly to the finish line to complete the challenge. Congratulations!
