    I gather the batteries are 3s? Because I feel the 447 props will be too big for 120A ESC's with 2800kv motors on 4s.

    But I would imagine that they are just as reliable as the others, if you don't exceed its parameters. And they can be programmed with the same...

    I think you'll find that a 28mm motor won't be powerful enough for a 36" hull. You probably won't be able to spin a large enough prop to get that hull moving fast enough. A 4074 or 4082 size motor,...

    I Thought so.

    Hi Tom. And Merry Christmas.

    Unfortunately a 1400kv motor on 4s might be a bit slow. that's about 21000 revs. Maybe 18000 under load.
    For 4s, something around the 1800kv range would be better....

    First of all Mike, Welcome to the forum.
    Secondly. What is the length of the hull? Does the '80' stand for 800mm?. Some pictures would be a help too.

    Always good to see another option. I wonder what the postage would be all the way down here to the Colonies in Australia.

    Ferrari Arno XI Hydro.

    It was one of those static display models that I added motor & hardware to.

    The 4082 1600kv motor is a 'Y' wind motor so about 11.25 - 15.00 degrees is good for either 4s or 6s. That's where I run mine.

    With the 180A ESC I would try the M642 (42/1.6)to start & M545 (45/1.5) if the heat is ok on the first one. Both on 4s. They might be too much for the 120A ESC.
