Awesome setup and results, there. I saw how things turned out with that high rake prop and almost ordered one myself to see how it runs. I watched Ironclad RC's video on 'props 101' and learned that those high lift props are for cats and hydros. You can run them on monos, but they have to be tuned to keep the rear in the water. There's no stinger to adjust on this boat, so we're kinda stuck with the 'wide thrust cone' props. I like the 4519, but I'm thinking a 40mm 3 blade at 1.9 pitch would be more blade area = faster
Love that you are running that esc, I find the esc is always the let down. Except I run in salt so I have many other issues from that. I am wondering if your 4519 was the AliExpress one ,if so my experience is they run like a 1.6 pitch in an octura roughly.
