Gass Umbra - Level 5

I'm having a little trouble getting through the level 5 speed run on Gass Umbra I get to a certain point into the run and just seem to stumble, I've tried a bunch of times and it's always the same place I fail... 


I'd appreciate some tips & pointers!

I guess I'd just climb up to the fly power-up and then hurry on and use fly when I eventually feel a need to. For instance if you're falling. 

This is how I did it:
I found the the bit after didn't need the power-up and it was easier to use it here. Remember to not press up too much when using the power-up.

Ah, thanks guys your help is much appreciated! I was finally able to get past it.
I think it was just my poor timing... Well, that and the fact that I panic on the timed runs!
