Kaneli has retired as elder and has now created a new training course in the Flight Range that he wants you to try out.
Quest Location
You can start this quest by talking to Kaneli at the Flight Range, which is northwest of Rito Village.
How to Complete the Quest
You can use the Paraglider to float upward and press the Dive button to quickly go downward. You can go either up or down through the rings, so you can try to dive through the first set, then use the Paraglider to float up through the next set, and so on.
Quest Reward
If you clear at least 15 rings, Kaneli gives you 50 Rupees. If you clear all 20 rings, Kaneli unlocks the advanced course.
