Hey all! I was out doing some tuning this morning and on a whim checked the capacitor for the first time and found it was surprisingly hot. Not burning/scalding hot, but not too far off. I understand it's caused by noise in the system, and this definitely isn't the cleanest quad out there, but there isn't anything nasty in the noise graphs. Could it just be I'm using too small of a cap? It's a 50v 330uf with ~2cm of 20awg wire on a 4s 5" quad. If you guys think it's too small of a cap, would I be able to just run a second cap alongside it wired up to the same pads? Thanks!

330uf is a little small for 4s. If you ran 2 330's instead of 1 470uf they would work faster and more efficiently. The heat is more than likely due to the cap not being able to replenish voltage fast enough for supply and demand.
