    Good Morning,
    I have ordered the mgm tmm22418-3s esc. It is a cont. 224amp esc and one tex suggested, tnks for that!!
    Looks like we have someone who has run both the pletten. and the neu. Peter tnks for your input! With that I do believe the neu must be the best for FE. Hard to complain if a man has used both. The video of your offshore is impressive, never mind the danger part. So that was a 60mph boat. Can you tell me what you think would put my boat in the 40-45mph range?
    If some of the other suggestions would meet that the specs for that I would appreciate your ideas.
    Disar, I think you get it, ie that I am not trying to build a racing boat! I have already ordered a very good esc that will be flexible and is respected. Not bargain basement, but good solid stuff. Now I don't know anything about the 45xl KB 11. I have read some on the feigao motors as they pertain to electric cars. Are they considered at least for my needs something that is solid and reliable? Tried to call the Canada Plettenberg office and am having some connection issues on my cell to up there but will get back to them as I can to ask about a 750-800/minute motor.
    Peter, again, if you say the neu is better than the plettenberg with first hand exp. you have settled the issue of which is better in a marine setting. It is hard for me to see how the pletten is more expensive as here in North America the canadian dist. prices are well below a comparable neu. I will continue to check on that though.

      The ESC you ordered is for max. 6s (6 lipos, 22.2V) as I saw in their site, but all the proposals were for 8-10s (29.6-37V), maybe I am wrong but please check again. Otherwise cancel or follow Peters advise (I think he was running 6s).

      If you have the money and you are determined to buy best quality stuff go for the Neu. If you want to save some money go either for the KB45 11XL (it is a big motor and in this site states suitable for 46" boats, however it was mentioned that is crap but I do not know why), or for the Feigao 580 12L (1051 kv). This is a new motor with 6poles (more poles more torque) but there is no experiense in big boats. You can use about 1000 kv on 8s (8x3.7x1000=29,000 rpm).
      Peter also stated 6s (I believe) in his boat, which means 29,000/22.2 = 1300 kv motor

        Sorry for any mixup.........................

        Richard in the youtube video the boat is running 4 packs of 5cell 5000 lipo's or to be clearer 10cells x 2 paralleled to give me a total of 10,000mah and 42volts sorry guys I should of elaborated more . I have run this boat just on 2 packs of 6c5000's or 6c x 10,000mah and got a gps reading of 75kph with a Neu 2230/1Y , schulze 40/160 esc and a 3 blade ABC 2616 prop . The highest speed I have ever reached with this hull is 114kph on 2 banks of 12cells at 5000mah per bank , prop was a 2 blade octura x460 if I am not mistaken

        6c2p generally means 2 x 6 celled lipo packs in a paralleled circuit , 12c1p would be just 12cells in series

        Curt its not that the Neu's are better both makers make a fabulous motor just in North America its cheeper to get a Neu , owning both I would have to tip my hat in the direction of the Neu's power wise also

        Neu 1527 = $285.00
        Plett 300/50 = $465.00

        Neu 2215 = $ 495.00 or less
        Plett 370/50 = $532.00

          I did NOT recommend this esc at any time,, I said it would NOT work on 8-12S lipo set-ups, which is what you will soon find out you need!! BAD DECISION ON THE 22418!!! It is not going to hold up, I have that esc, and never run it on more than 6S total, which will NEVER power a 46" hull... Please reread my posts.. You are mistaking, and it will just cost you more money in the long run!!



          Good luck Sir!
          Nothing like keeping you lipos warm and your prop wet!!

            OK,,4x 5000 for 10S 10,000mah total,, that is what I run..Sounds right for what I saw in your video.. I have never tryed the 2215/2Y or 2230/1Y on anything other than 10S, so I dont know about your 6S2P trial at 45mph..... With a x455 prop, I get 55+mph on 10S with no heat issues,, running 40" Insane Cat and 44" Avenger Pro Cat...



            6c2p generally means 2 x 6 celled lipo packs in a paralleled circuit , 12c1p would be just 12cells in series
            As well..

              Curt, please listen to the guys that have run big FE boats. Why did you purchase that ESC?
              Ask them for a sport setup, if you wish 40 mph as your target speed. You need to learn that the ESC is generally a fuse and you should allow for a 25% cushion....200 amp rating 150 max ....12S rating 9S max. With boats the amp and voltage draw are at the max most of the time and the ESC hates part throttle useage....Boom
              PS the KB45 is not a good choice. A badly built motor and I doubt it would power a 46" boat

                  Ok, I have canceled the esc. Now I am back to square one. Will reread the previous posts to try and get the correct esc for I am not sure which motor, will need to see if there is a sport setup that does not use the KB 45 now. Where are the vendors you recommend for the motor. I pretty well need to stay with the one on the esc purchase since I canceled it. It is a local hobby shop and don't want to make them mad.

                  So Sport unit:
                  1. right now only the neu 1527. I cannot seem to find that motor for the price you have listed.

                  2. ESC- must be able to withstand 250amps cont. and a 6cell 2pack battery system of unknown voltage?

                  3. 2- 6cell lipo packs right now of unknown voltage and a vendor someone has already mentioned as a good source. I will go back and find the name of that vendor here.

                  I went to the feigao 580 but could not find much on it. If everyone can agree on the neu 1527 as a motor that will get me to 40-45 I will do just that!

                  Oh forgot to put this in, I am totally guilty of being a wanker, what ever that is scottsman!!

                    Good idea..

                    look here at ose,, 1527/1.5y 850kv...http://www.offshoreelectrics.com/pro...u-1527&cat=117


                    2. ESC- must be able to withstand 250amps cont. and a 6cell 2pack battery system of unknown voltage?
                    Voltage will be between 24-42 depending on 6s or 10s lipos....You dont need 250amps cont.... only about 120-180Amps cont.. look at the castle hv-120 or hv-180 here at ose.... I have both and they work great..also they go up to 50volts or 12s lipo...http://www.offshoreelectrics.com/pro...ra180-highvolt


                    3. 2- 6cell lipo packs right now of unknown voltage and a vendor someone has already mentioned as a good source. I will go back and find the name of that vendor here.
                    get the best your money can buy....

                    stay away from the 580,,, go with the proven neu's....

                      I agree with Richard on the Neu 1527 you will not be disapointed . this motor can easily rival a nitro 60's power output

                        ready to go. Only thing i need is the specifics on the 2 battery packs.

                        I definately need the site that helps you figure this out based on your motor specs.


                        tell me again on the lipos.



                        I am only running 14.8 volts total on my emaxx and each battery is a 2c. This I understand! 2 packs, each has 2 cells @7.4 volts. In series I get 14.8 volts and together I have a 4s pack if they are charged together.

                          Here is my take...forget that big hull!

                          You will be faster and money ahead if you downsize the hull and build something that runs 6S with a 12Xl or 13XL. 120 amp ESC and a few 3S packs to run in series.

                          It will cost you more to try and get what you want from that big hull than worth.

                          You want to spend $1200 just to be able to use a $200 hull?

                          Get one of the 33" boats from OSE and have a good boat with excellent run time low heat and you WILL be impressed wth speeds.

                          Just another school of thought for you.

                            With the 1527/1.5Y,, I run it on 8S lipo or 2x 4S 6000mAh 25C packs for 8S 6000mah total.. I have never tried this motor on 6S lipo.. I would STONGLY recommend going with 8S lipo set-up rather than 6S... It will be easier on your wallet in the end..
                            Also it will be easier to get to 40-45 mph with 8S lipo total (32volts fully charged)..

                              I don't believe you get it!!!! I am not looking for speed!!! How many times do I need to say that. I want a big boat to play with that will do 40-45mph. Why is that soooooo hard for people to understand.
                              I am now a sport boater. Been out of racing for almost 5 yrs. The money I spend will be for something that is solid, and predictable. Yes it takes more to move the big hull THAT I WANT TO PLAY WITH, what is wrong with that. I am not going to spend the bucks to make it a 60mph boat because it is not made for that speed. It is a scale looking offshore with too much freeboard to be a racing hull and the wrong configuration of strakes to go that fast. At 40+mph it is stable, and predictable. Man what is wrong with wanting that.

                              Look guys I feel I am beating a dead horse here. IF this is not a site for a sport boater to get help with a large epoxy very light hull to go 40+mph on electric power, please direct me to a site that will accept that. I am getting pretty worn out with those who want to tell me what they think I need, I guess for racing, that is simply not on the table for this project. HAVE FUN, SPORT BOATING, ENJOY IT WITH MY GRANDSONS, ETC We are on the 59th post on this subject and I still need to say that to people. What can I say.

                                Batteries, as previously stated the best you can afford... rated at 25C or better with 12GA or 10GA and 5.5mm connectors and keep the wiring between the ESC, batteries and motor as short as possible
                                Jeff's comment was meant as an economic solution. If, you have the cash, go for it but be aware of the pitfalls
                                All other FE sites will give you the same resolutions
