Can anyone recommend a ESC program setting for this motor. I am using it in a 800mm long motor cruiser. I am having difficulty getting the motor to run smoothly at all throttle setting and difficulty in getting it to go into reverse
Hi
I have a 4ft Torpedo Boat with 3 prop shafts, and am thinking of using 3 x 2848SL 3900kv Brushless Inrunner (Water Cooled) motors.
I have been using 1 big motor 3660SL 3180kv Brushless with pulleys and belts which drew to many amps and burnt the wires off the motor.
Any ideas welcome
Thanks
Stan
i would advise agenst it as the speed will be to fast unless that is your intention
i would sugest a outrunner motor from a small heli up to 450 range no bigger much cheaper and you wont have to run any water lines and alot less amps on esc that relates also to cheaper esc
Thanks for info.
I am going to run with the 3 x 2848SL w/cooled motors.
Yes I am looking for speed, the original boat (a Malaysian Torpedo boat PERKASA) had 3 x 14,000hp Roles Royce Gas Turbines and was built in England.
It was the fastest boat registered by the British Navy.
My model draws 20 to 50 amps with 3 x 35mm 2 blade racing props to reach full planing and I expect these motors will smooth out the amps used.
I hope.
Stan
In all honesty I would still go out runner I would buy 3x turnigy typhoon 450h 2218h motor 3450kv these will out perform the above motor and be cheaper
Yes I do love the perkasa patrol boats might be next on my boat list
I would use 3s 2650-3000mah depending on boat size.
at least 50A water cooled ESC
i would start with a 32mm 1.7 cnc prop from HK if your drive shaft suits. PLEASE GIVE CREDIT IF HELPFUL.
A 5000 3s and a T180 is too heavy for this motor in a 'fast' boat. This motor would suit something like the centurion catamaran. If space no issue then use a 6500 80c and T180 for sure. Just make sure good cooling for ESC if low speed, hard working (or fast) boat.
this motor is DOWNGRADE for the super surge crusher AND seafire. I would use this motor... PRODUCT ID: 020000001 on 4s and start with a small prop ~35mm 1.4 pitch or something.
no its not, there are hundreds of props avail on the net. it will be either 4mm or 5mm or 3/16th shaft size.
I would remove the stuffing tube and upgrade to 3/16th on both of them if they were mine.
hello!! could let me know! which esc (50/60/100 /) suitable for this motor and battery?

hello made **an engine burns if it just ok, I reducte engine I divisepar both its logic to consumption, always depends on what the research on speed, and I play on the propeller box, and fun go
60 ok water esc no problè*me
its a motor with a cooling jacket on it nothing more than take it off and fit in what you want!! however its to small for the slash it would be a waste of time
will fit in the 1/4 gokart
Three ways to get water through the motor - 1. a water pickup that is part of the rudder assembly (common). 2. a water pump that pumps the water from a pickup (used for very large high-power boats). 3. a separate water pickup that pushes water through the motor and ESC when the boat is moving (common for smaller boats)
Use silicon tubing. Route the inlet to the esc, then loop it back on the other side of the esc, continue from the first side to the motor and then to the outlet. 5 mm outer diameter works for me, the inlets are 3 mm at their narrowest. Haven't found proper tubing at HK, though.
also it is wise to have the water enter the lowest nipple on the motor cooling jacket and the output nipple should be the higher one so the cooling jacket fills up completly for the best cooling of the motor.
order the motor on its own, shipping is only 5$ for the motor alone. If shipped with lipo batteries, it will delay the order significantly. I have received mine in around 10-14 business days in Canada on both occasions.
I have never had that much trouble getting something from Hobby King the shipping on all items I have ever ordered came within 10-14 days as advdeertised, did you guys get something on back order? if so you should wait until they say they have it use you wish list next time

correct length is 48 mm without shaft, diameter is 28 mm without cooling jacket, 31 mm with it. It must be used with a min 40 A Esc, but bigger is better. U can use it n eco class or in mono 1. It's a very good choice for eco expert class.

Bought this motor for my boat, but it's winter, the pond is frozen and I needed a motor for my FunJet. So I tried it. I removed the jacket and flew it on 3S 2200 with a 60A Turnigy ESC, works awesome. Doesn't get hot but then again it is winter now.
Great motor for mini boats. I am using this motor in a NQD jet boat. Using 3s battery due to hacker navy esc only taking 3-10s lipo. I am using the esc's power option to tame the output to 50-75pcnt. No idea of amps/watts, but I abuse the boat with 3100MaH 3s 25c lipo with 20mm jet prop, NO PROBS:) Motor has 2 mounting options - 16mm and slighter bigger, sorry didn't measure. Nice water cooled metal jacket plus 3.5mm plugs on motor leads. Very nice deep blue colour and good quality. I am happy with the purchase and recommend. Thanks Hobbycity.
