    ESC Advice

    I am currently building a Fightercat Cheetah with a TP 4070 1440 kv motor. I plan to run this on 6s2p with a x452 prop. Would all of the ESCs listed below handle this set-up?

    Swordfish 220a 2-6s
    Hobbywing 180a
    Swordfish 200a 2-8s

    Thanks for the help.

    Hobbywing 180 would be my first choice. Make sure you add a nice cap bank to it, disconnect the bec and add an external one. It's easier on the controller....

    I would not start out with a 452 prop either. I'd start with a M447 and then go to an x447/3.....with these props and the rpm your going to be turning, your going to do about 55mph. If it were me I'd opt for the 1650kv version if you have not bought it yet. Don't pick a motor more based on y wind or d wind. ....put it based on your kv needs. I started running d winds (which I thought were the devil) and it hasn't made a difference in esc temps or anything.

      Easily, you might draw in the area of 100-120 amps with that prop.

        If you're going to swing a 52mm prop on a TP4070, I'd go with at least a SF240 just to be sure to have enough head room. I've got a 4070 1870kv in a Q mono 37" TFL Ariane it draws 160 pretty constant with spikes a little over 200.

          I agree but I think the 52mm is a little too much. That's just what I think tho....

              I'm running a Prather 235 which is 50.8mm say 51, 1870kv and like I said I get spikes of a little over 200 and temps in the 115-120 range. So with 1440kv he should be able to swing a 52mm no problem

                  Maybe so, but I prefer to start small and be cautious. That's just me tho. I don't like

                    Yeah I know what ya mean, but another thing to think about is my setup is in a Mono and usually Monos pull more amps than Cats so he should be safe especially if he gets a SF 240.

                      I just put this same motor in my 36" Sprintcat, with a SF240HV pro+, 6s2p, and a X452 DT'd, with cup and pitch added by Dasboata. I have also tried a Prather 240 for a couple short runs. Now, my 452 is obviously just a little more prop than a stock one but this is what I have been seeing just to give you an idea. Various strut heights, but all around +/- 1/2" up- spikes as high as 270 amps, with an average of 180 with regular spikes to 235. Speed is about 57mph on 6s, and 65mph on 7s. Temps on electronics have been fine, but my 8mm motor bullets get pretty hot, 200 deg. This is running for 2-1/2 min, at full throttle through the turns for most of the run. Personally, I wouldn't want to go any smaller than this 240, and FWIW, this new version II Pro+ runs WAY cooler than the previous one that only had one set of cooling tubes. Not sure if your hull will run looser than mine, maybe.

                          Well....the esc's he listed are "budget" esc's, so he may not want to spend double the price on an esc......not everyone is Has got that cheese ($$$) like you do to afford that thing. Lol

                            The SK180 is great, but personally I would not feel comfortable running a motor of this size if you want to take full advantage of the power, especially as a single, but that's just my opinion.

                              Hey i agree....but he may not have the coin to drop on a SF 240. ....altho my t180 has been running my 1521 just fine.
