High an easy way to figure out if a battery/motor combo will work is some simple math. You want to keep a mono prop around 30K ish max ideally.Hydros and cats go a bit more usually. So 4500kv x8.4 (2s LIPO full voltage) =37800. Might have to reduce end travel a bit or cavitaion could kick in depending on the prop size. But it should work
