I'm trying to learn 120% and saw how people just fly straight up to the plane, but when I tried it I hit the ceilling and can't figure out why
Hey Dstrike_Zero! We have a trick in this game called height cap break that effectively allows you to trick the game into thinking Spyro is flying down while he's actually flying up :)
If you watch back a run with a controller viewer, pay close attention to the left thumbstick. The way this trick is done is by holding ever so slightly up on the thumb stick while holding down on the dpad, and then letting go of the dpad prior to the height cap being reached while maintaining the thumb stick position.
What this does is tricks the game into thinking you are moving down thanks to inverted flight controls, but thanks to the held control stick, Spyro is actually being forced up :)
It's a tough one to explain with text alone, but if you want to record an attempt of you doing the glitch with controller inputs, you can jump in the discord where there are loads of people who can help you out with this! Would highly recommend if you're looking for feedback on things that aren't working like you think they should.
Also check out this guide, timestamped to height cap breaking. It's for Spyro 2, but works exactly the same across all three games:
