Alright so I've done 5 min in tunnel and tried level 3 again. annnd passed!
for some reasons I thought I arched perfectly up there, I was stable, super happy that I'm flying. But when I watched the video, I saw that I'm flat! there's no arch but still flying right?
what's your thoughts? anything that I can improve to be more stable? level 4 is 90 degree turns and I'll be needing more arch i guess
