    Your 1515/2.5D motor is really too much for 6S except for racing. It would work fine on 4S but 60 mph is out of the question. Run an x445 for sport and an m545 or m645 for speeds in the 45-50 mph range on 4S. If you want more speed you'll have to get a different motor for either 4S or 6S, unless you enjoy buying ESCs regularly.

    The 'M' series props are just like the 'X' series with the same number, except they have some blade area removed from the leading edge (tongue).

    Fluid I was hoping you would chime in....I thought I was going to have to pm you

    first of all I found it hard to believe he was running 6s on a 2500kv motor and living through it without causing a melt down

    My actual first choice for the motor going in my MM is my 1515/2.5d 1650 kv

    I heard good things about the Hi model 200 esc and ordered one two days ago I will modify it with Steve's cooling plates and then water proof it

    My plan was pairs of 3s lipo's or one single 5s.....please give me your choices for props to go 40 50 60+ mph

    thanks in advance

    M or X 440, 70 amps, 40mph+
    642 or x445, 105 amps, 50mph
    645, 135 amps, 60mph
    646, 145 amps, 60mph+
    whats the difference a m or x prop.....is this info all on the 1512 motor?

    I would run them with the Y537/3 prop. Not to many watts. It works well on the MM hull. I have a new prop that would be like a Y538/4 that I am going to try on the MM.

    Cant help with this setup. Maybe someone will chime in from their experience?

    Hi model 200amp

    11XL and even 12XL on 6S amounts to too many watts, not so Reddy? Thats why I used 13XL on my 6S set-up in a 31" cat. Would the 11XL on 6S in a MM hull be that much different?

    Any more exciting MM set-ups? I am on the verge of ordering one, selling all my 3S packs and using my 11XL on 5S2P in this hull. Would start with the X442 prop, or not?
    Then I will de-convert my TC31 back to nitro...

    Quick question, is this hull/prop considered a SUBMERGED PROP or SURFACE PROP that would run on this hull.

    Reddy,
    Lookin' Good, very stable and controllable....
    Did you happen to get any temps after that run?
    Do you think an 11XL would work on 6S in that hull, and if so where should I start with my prop sizes, Y536 or smaller? I am thinking about picking up one of Remy's flood specials and giving it a go.
    FeCalc estimates:
    Feigao 11XL on 6S, Y537/3 prop
    73 amps
    1500 watts
    30300 rpm
    50 mph

    Feigao 12XL on 6S, Y537/3 prop
    59 amps
    1250 watts
    28150 rpm
    47 mph

    Guys this is not my boat. I added this setup to the thread as another option for anyone wanting to build a Mean Machine. It now shows setups for 4s, 6s and 8s in the MM. Take your pick.

    just ordered an mm hull and hardware, the guy is great , hull and hardware for 95 bucs how can you beat that. fluid would love to see more pics from diffrent angles of your boat. also am a little confused, looks like mr watts uses an awful lot of batteries, are 2 25c 7.4 5100 mah lipos going to be enough if i install the neu1521 you are using, steer me in the right direction still kinda new to this so the 4s compaired to 2s thing is throwing me off, does this mean you are running 2 2s or what looks like two packs in your pic thanks hate to sound dumb but want to be sure
