I just got my UL 19 today. Was thinking of running 2 4s packs parallel. 4s packs don't fit. Do people just run 2 2s packs in series for P-limited class Namba?

2 2-s packs in series will give you 4-s voltage. If you want to run 2 4-s packs in parallel and yours won't fit look into buying smaller M amp packs.
All packs list size, usually in mm. so you can determine if they will fit or not
before placing your order. MANY different sizes available if you look around.

I run two 3s packs and they just fit. The factory wiring is in series so the 3861 motor sees 6s. the stock prop is all wrong and I have an Octuro 440 to try , balanced, sharpened and polished ( careful of the dust and don't polish dry , I use 10000 grit lapping Clover/ oil with Dremel cotton buffing wheel).
