Impulse 31 prop

[Defenderjosh]

Hi guys, I've recently purchased a impulse 31 and am hooked with it (it's my first boat), atm it's totally stock I'm running 6s 65c batteries, what prop can I upgrade to? Also any other upgrades recommend?

For whatever reason, the Impulse 31 V3 never got much love on this forum and there are not many threads on it. The stock prop is the same one used on the Proboat 29" cats and is just a fraction of a mm smaller than an Octura x440. Assuming you're going to run the boat on 6S, you can go as small as an x442, or a little bigger with a x642 or m545. I just got my Impulse back together and plan on doing my shakedown runs with an x440/3 prop before I go bigger.

FWIW, I ran my Impulse 31 V3 today, stock electronics, Wohlt's wire drive, 3S Revo graphenes, with a Dasboata ABC 1716 prop and ran 58mph today in pretty good conditions. Definitely a SAW setup, not super stable, but the temps were all in check. I think that's about the limit of that boat, just too squirrely at that speed.
