    FAST 6s setup prop help

    After testing my latest boat (30inch sprint cat) on both 4s and 6s with an m545 prop, i would like to try out some more options for a higher top speed. temps were fine with only mildly hot temps after full run on 6s. but on 4s was only getting like 44mph and 6s "only" 60mph

    since the boat has an 1800kv 4074 motor its got lots of low end torque and I think it could do a lot better with something like this https://www.offshoreelectrics.com/pr...rod=cnc-4816-D

    i would run that on 4s and possibly use this on 6s - https://www.offshoreelectrics.com/pr...rod=cnc-4616-D

    im just wanting opinions on this, i only have a 150amp esc in the boat and im planning on adding extra caps to it. maybe the 46mm is to much for 6s (although testing with m545 is was fine) and I should get the 42 or 44mm version with same 1.6p and detounged.

    not sure??? what do you all think?

    thanks!

      How about an ABC 1715 or 1815 both with 17 degree rake. You could also go with an Octura 645, That is usually a good bit faster than 545. It was my fave on my 30” Geico with a 4074 Castle motor.

              Runs great though im not a racer or anything but it was very fun building in it and it handles extremely well compared to my other smaller cats.
