    Was actually looking at that same motor...planning on getting the 2364 version in the coming weeks.

    First day out with the Spartan and she gave out on me (thinking it's the RX), but with all the unreliable talk on here I say I might as well upgrade everything, hence why I'm looking for other options.

    if your planning to run 6s I would stay away form that one, to much rpms
    the 1828kv would be a hot one
    even the 1391kv with a 47-48mm prop would be awesome on 6s

    Mmm...meh, I'm one of those who like to have the extra ummphh available when I want to use it... (So yes, you are correct for me it's 6S or die)

    I do plan on also getting a lesser kv motor around ~1700 as a backup/tester.

    But I hear what you're saying film...with those RPMs I do expect things to 'heat up'...literally. We'll see how it goes.

    I appreciate your advice though...much thanks to you, wilson and dag-nabit just to name a few. Very informative posts!

    boats are much different than cars bro
    to much rpms and all you will have is smoke, and that's because FE Boats pull so much more amps than cars and trucks
    higher rpms can kill a setup rather than be faster

    If you go with the 1391 or 1828Kv model rated at 76 and 88 Amp max respectively, the 120 amp ESC should be a good match.

    The 2039 at 98 amp max might be fine with a 120 amp ESC as well, just not sure what kind of spikes that motor might pull.

    Good Question,

    The 4074 would be nice because the 40mm can should provide better torque, but I don't know anything about these new Keda motors.

    I haven't run my Tacon motors yet, but a google search reveals most people are getting good performance and reliability from them.

    So the question is do you go with something new and relatively untested (I haven't found much info on them yet), or with something that has some history behind it.

    They also could be great motors at a decent price??

    hey bro, that esc should work just fine, just don't over prop it
    somone keeps posting amp ratings of motors hear but forgets you can pull way more amps that the charts show if someone over props these motors and with a good size prop, the motors wont pull many amps at all and the esc will be just fine

    and being the Tacon motor is cheaper and a good kv I would pick that one

    Speaking of charts...is there a chart or speed calculator for measuring boat speed, using batt. type, prop type, motor kv etc? Something similar to this for cars/trucks.

    Edit: Ok, OSE is the best...found the info. I was looking for on there.....

    Yes I do. And I'm aware rated amps on motors and ESC's are continuous ratings and that both can handle bursts above the rated capability.

    Using the amp ratings of the motor and ESC as a guideline for sizing is a good starting point.

    And I didn't forget anything, I chose what information I wanted to provide, and it was pertinent and should assist the poster in making decisions.

    Sometimes you have to balance between writing a novel and trying to cover off every little nuance, and crediting the person asking the question with having some experience and knowledge, and just give a direct answer.

    That said, you are correct Film, prop sizing is an important factor to consider in the decision making process.
