Hello!
I'm currently working on Chopin's etude op 10 no 4 (Torrent). I've learned the first half or so, up to bar 37. It's not too bad and surprisingly I can already play parts of it at speed. A major bottleneck I've identified so far is (as the title says) the arpeggios in the right hand at bars 3, 11, 53, 61 and probably more. I'm having a lot of trouble hitting these RH notes with precision. Does anyone here have suggestions for this?
Because the broken chords are so spread out, it becomes an series of jumps in the RH and it's quite awkward (at least how I'm doing it right now). Another problem seems to be that as I'm preparing to hit the upper note with my pinky, my thumb drags on the lower notes so I can't get to the rest of the arpeggio in time. Right now my instinct is that I should let my arm do most of the work in moving my hand and use the fingers to "aim". Even still, it doesn't seem that I've found the optimal motion to do this, so I was wondering if anyone might have specific advice.
The fingering I'm using is the one in Cortot's edition. Images of the relevant sections:


Thanks!!
