2040SL 4800kv Brushless Inrunner (WaterCooled)
Mattyc (238 points)
  i think this would be far to small for a 36 shockwave, just going on the shaft size id say that its a smallish motor, get a kb45 8L for the shockwave and a turnigy 180amp boat esc, and a couple of flightpower 30c 2600mah 4s lipos to run parallel as 4s2p.. you should see 50mph with a decent driveline setup
-Reply from Madmax64 (1 points);
You will need a bigger motor 3660 model whit 2000kv to 3500kv rpm. Max

  What's the best speed you got from this motor installed in a mini hydro? Will it survive 4S?
-Reply from Eric1180 (2289 points);
common sense would say 4s with a 4800kv!!! motor would be to much. Thats almost 70,000rpm unloaded way to much. 3s is almost pushing it
-Reply from Dirk (13 points);
2s is best, if you got more kv, select the 3060 Kv

-Reply from Madmax64 (1 points);
Le mieux c'est un esc marin! donc avec un systeme de refroidisement a l'eau, il doit ètre résistant a l'eau(waterproof ou marine) , avec une puissance de 25a au minimum. Moi j'ai un 35a seaking . Max

-Reply from Crashinbash (222 points);
In a 36 inch you'd probably want a lower kv with more torque.

No, it would not. Think about what you are asking for a second. a 20mm motor for a 36inch boat!?!?! you need a 40mm motor MINIMUM for a boat that size.

-Reply from king_draki (40 points);
You need 1 ESC per engine. I recommend 40A ESC for this one. But for 82cm hull buy a bigger one. This is good for micros <50cm.

  would that motor fit on 550brushed motor place and wat esc should i get with it. ihave 30 in boat
-Reply from RC trk (170 points);
The overall size would fit but the mounting holes is not a direct fit, this can i smaller than a 550 brushed it's only 20mm in dia
-Reply from Madmax64 (1 points);
You will need 36mm or 28mm motor and 60a ESC or more !

  I used a 26mm prop (slingshot by compass), 40A esc,11.1v 2700mah 30c 3 cell lipo(new)with about 30 min run time, a new 2200mah 3 cell 25c battery got hot and puffed up, in a striped Aquacraft Hammer abs plastic hull. It got about 27mph, It Jumped out of the water when full power given at start. My setup had Zero shaft vibration, On 10th run went to 24mm prop got better rpm, lost 2mph and then the magnet armature broke in half inside the motor and jammed up. Worst motor ever! I WANT MY MONEY BACK!
jimbo171 (39 points)
  Would this motor be a good replacement for the Delta Force 16". ??? The stock motor is a 2200kv with 3s 2200mh. Would the stock 45amp esc be enough for this motor???
-Reply from AM1508 (20 points);
guess not..its way to much kv's!! with the same prop these will suck more than use a much smaller prop or reduce the kv..try between a 2800 or 3200 kv motor on 3s or use a 2s pack with these motor and a 28-30mm prop so you can use your 45A esc..greetz

  Can this motor be used to upgrade from a Brushed Graupner Speed 400 7,2V? i use 2 motors in my boat. what ESC would fit 2 of those motors? tks guys
-Reply from steamboatbob (5 points);
depends this is a very high revving motor on 7.4V it will be generating 35,000 rpm and it does get very hot when a small load is put on it
if you are replacing twin 400s i would actually go for the next size motor up as this will give you more tourque this motor is really meant for micro hulls.
-Reply from boatee (340 points);
To run two motors use two ESCs. I'd use 2 30/35 amp ESCs fed from the battery with a Y cable (available from Hobbyking) As for the voltage, the maximum it will take is rated at 11 volts so your 7.2 should be OK. Id be tempted to spend a little extra and get two Turnigy Marine 35A Brushless Boat ESCs. Well built and rugged. You certainly won't have any heat problems.

-Reply from Phill63 (139 points);
If it will fit in your boat mechanically then you can use them. Use a seperate ESC for each motor. You could run each ESC on a seperate channel in your Tx and then mix the channels to get a balanced power output, or run a "Y" lead from your Rx to each ESC.
-Reply from Adam (9 points);
i use a 25amp with mine although a bigger esc would be a better safe guard

a cooling system is already mounted on these motor..u just need a "water intake" -> flexible tube to everything to keep cool (most: motor and esc) -> flexible tube to "water outtake".. i hope this helps you a little bit
-Reply from QIK-RX (29 points);
Have a look here, might explain it a little better:

-Reply from steamboatbob (5 points);
usually the rudder on your boat has a water pickup and you can connect that to your motor using silicone tubing.

If you ar going to push this motor to the limit , then 35 amp is not enough. 45 or 50 amp is needed for racing.

Have you test it out yet? I have the same set up for my mosquito craft but i havent test it out in the lake yet so idk if the esc will get hot. But i tested it for 5 mins full throttle without water cooling for the esc and it was still cool. But again that was without shaft or prop and outside of the water.

  can you put this motter in a 27inch hydro plane
-Reply from GliderJack (6 points);
This Motor in a Plane? No! This is a Inrunner Brushlessmotor for Boats. If you need a Motor for your Plane, look for Outrunner Motors (or inrunner-motors without WaterCooling) -Remember: Inrunnermotors are getting hot very fast... Thats Reason why I'm only using Outrunnermotors... ~Vijay
-Reply from Alex (9 points);
Nah man i i was you id go for something a bit bigger. like the size up from this 2848SL 3900kv Brushless Inrunner then it should be all sweet :)
-Reply from waterlogged (3853 points);
A hydroplane is a boat. DUH! You could put this in a boat, that's what it's built for but I think the 27 inch would be a bit much unless you use a small prop and run on 7.4 volts 2s. It's only a baby so it's really suited to much smaller boats like the Cobra.
Alex (9 points)
  The motors max voltage is 11v but will running 14.8 burn it out straight away or will it just get hotter faster?
-Reply from GliderJack (6 points);
With 11,1V its getting hot very fast... You cant use it without watercooling with 11,1v, bescause it would get too hot. I think with 14,8V watercooling would not help. I'm sure that this little powerful motor will burn out... :-/

The size of the boat is about right. The ESC would do the job too. Prop should be around 31mm. Look around, HK has a number of smaller sized nylon props as well as metal ones.

-Reply from waterlogged (3853 points);
This little motor really screams and would be a good motor for your boat. Just be careful fitting the cooling hoses. If you put too much pressure on the especially sideways they will snap. Try soaking your hose end in hot water before fitting. It will just slide on easily.

-Reply from fastnut007 (18 points);
running on 3s this motor is too high a kv ,suspect you want forward and reverse ,look at car motor with sensor link to ESC approx 2300kv min 200watts ,? what size prop?

thanx james but i don't need a esc because i want it just to go straight.
i need a brushless one and the prop size is 25 mm
-Reply from fastnut007 (18 points);
hi again ,still say kv`s of this motor too high on 3s for what you want ,something between 2500/3000kv`s would run cooler and longer on a 25mm prop calculation ,3sx4400 run time 30min`s equals max power draw =100 watts ,hope this helps,cheers.

I think, use this one for submarine with 3S is not good idea. The best use this motor with same size but small KV1800 And water cooling jacket like this so you have same watercolled boat motor but with small power consum.
-Reply from Morten (1 points);
Lower KV if you have to use 3S, but maybe if you use an 2S. Remember to get cooling to this engine, mine got burned after 1 -15 minutes with a failure in the cooling circuit.

  Hi could someone please tell me if this motor is compatible with a Turinigy Marine 35A Brushless Boat ESC and a Turinigy Nanotech 2200mah 3S 45 90c Lipo battery? The reason I ask is I'm running this set up in a Tearinto jet boat and only after 5 goes on the lake my engine has overheated an is seizing up.I have full flow of water running through the motor before the ESC... The first 3 goes on the lake everything was normal, on the fourth go the motor was warmer than the battery and on the fifth trial only got 3min before motor stopped.Have only had the boat up and running 2 weeks and never run twice in the same day..Any help would be much appreciated.
-Reply from Lathalini (96 points);
You could try getting the water cooled motor mount and also adding another water intake somehow. I fixed this motor on and old toy mastercraft boat from new bright. Im running it with a 50A birdy esc and 3s. Mine hasn't burnt yet.

I use the 50A birdy water cooled esc. I have run the same motor in a 500mm home made Jetboat with the 50A Esc and it runs really well. Read the reviews on the esc before buying, I here many have had their esc burn out. However I have 2 that are still running realy good. I have tyed both 2 cell and 3 cell. 2 cell run better in a jet boat, but there is a hell more power on the 3. hope this has helped. Cheers.

No worries. The impeller in the jet unit is 20mm diameter. This motor could run a 30-35mm prop. That would be the maximum I would run in a boat that size with this motor.

-Reply from ShamrinHM (578 points);
If i may help, 29" boat will suited 28 or 36mm motor. These motor is way too small for your boat. These motor for me is for small boats (less than 500mm).BTW if i may ask, what will be your target? speed? 2S or 3S set up?
alpha (1 points)
  the speed i want is 40 to 50 mph if i could get that.
-Reply from ShamrinHM (578 points);
Above 40s, with these motor is hard to achieve that.
Take these 36mm motor PRODUCT ID: XK3674-B-2200
ESC you can use these PRODUCT ID: TR-M-120A
Prop, either PRODUCT ID: 377000016 or PRODUCT ID: 215000008 (currently available, others is backorder)
Lipos, single 4S or 2x2S in series rated above 30C
Im running my 31" mono with that motor on 4S, 45mm aloy prop (mentioned above) and reached 40mph with no problem. Hope this help.
-Reply from ShamrinHM (578 points);
Btw, you need to buy cooling jacket from eBay, search for 36mm long version cooling jacket or just buy these PRODUCT ID: 151000016.
Just make sure you drive system is 4mm or bigger. So it will last long due to more current/amp flow from all the electronics. Sorry, im talking too much here. Hope this help.

Do not worry about the stock MG17 i owned the MG 24" version and it has 3.17mm prop sure the 17" version has the same or slightly smaller diameter too..if smaller, you just need to put shrink tube on the prop shaft for adaptor..Hope you get me..

  Sharim just got around installing everything on the miss geico 17 just got a couple of questions got a hk item number 9261000008 esc and bought an octura 427 prop , regarding the esc if you hit reverse I will keep running on reverse until you hit forward is this normal
-Reply from ShamrinHM (578 points);
Regarding the HK esc, i owned the 50A version and it's hard to understand the programming and i just change the running mode. Anyway, how did you programmed your esc? Make sure to use only 25% Reverse Force only.
bryan (2 points)
  Also have to play with the wires if I hit forward it I'll go the other way at least against the prop an vise versa
-Reply from ShamrinHM (578 points);
Yup, you are right..need to play with the 3 wires and just make sure when you hit forward your boat/motor move forward too..hehe..anyway, have a nice day and happy boating.
bryan (2 points)
  Sharim I'm stuck with the programming how do I do it can't get the instrucctions they r not on the web can you give me a basic set up with the control peaseeee heeeeeellllpp. Thank you
-Reply from ShamrinHM (578 points);
Sorry to hear that pal, anyway basic programming is using Tx/ steps as below:-
1- Connect your Motor to the Esc
2- Switch ON you Tx and put/push your trigger on FULL SPEED
3- Then Connect your Esc and Lipo together
-Reply from ShamrinHM (578 points);
Make sure your Trigger still at full speed after these 3 steps..
After that, you can hear programming tones..after 3 musical tones, there will be another tones (optional tones, 5/6 different tones)
If i were you i will only change the 1st setting, which is Movement (forward and reverse options),
-Reply from ShamrinHM (578 points);
Wait pal, there is still another steps, i need to type it step by make it simple, try download manual from Turnigy Marine ESC on a File Tab, from there you will get what i mean.
bryan (2 points)
  What then Sharim it keeps beeping will it ever ? When do I let go the trigger ? How do I know is ready ? I. Used to the old school electronics on rc sorry man thanks for the help by the way I'm in puerto Rico where r you give me your e mail so I can post a picture iPad won't let me post it here for some reason
-Reply from ShamrinHM (578 points);
Once you let go the trigger it will enter to the program options, this will be difficult..just change the 1st options only so that your esc can responded to all..
after the single tones let the trigger go and you will hear another tones, Then put ther trigger on Full Speed again after another single tones.
-Reply from ShamrinHM (578 points);
Disconnect your lipo and esc, then
try Reconnect it again, it should be bound already..
Hope everything alright. Good luck pal.

-Reply from ShamrinHM (578 points);
Hye Bryan, my esc behaved like yours boat suddently stop like the Rx dosen't received any signal from the Tx and the motor beeping a lot..i tried with new Rx and even another Tx and still the same..may be this is the bad things about that esc..
-Reply from ShamrinHM (578 points);
Btw, if i were you i will use these esc PRODUCT ID: TR-M-35A very reliable, waterproof and very easy to programmed and it has reverse too..i have these on my Centurion mini..
-Reply from waterlogged (3853 points);
The ESC could be cutting out due to overheating. Try increasing the water intake by fitting a transom intake. I've seen a piece of copper tubing and even a piece of carbon fiber pipe cut a 45 degrees and epoxied to the transom to pick up water. Run the two intakes through a T piece and always go through the ESC first then into the motor then over the side. Make sure you wire tie the hose fittings to stop blow out from pressure.

  what size motor would I use on a 600mm police boat fiber on balsa hull. This is not a speed boat more a scale boat so I don't need it to fast.
-Reply from benjamin (56 points);
Use a 2850 motor with a low kv. something like 3000kv with 2S battery.
-Reply from Yojik (7 points);
For a scale police boat of that size, I 'd rather use this one: Turnigy D2836/11 750KV Brushless Outrunner Motor with 3S battery. If speed really isn't of any concern a 2S would do too. 3000kV is way too much for this project.

this should work for you with a 28mm propdont try to go more the motor wont handel it.
-Reply from DaVilla (44 points);
I've used this on a 30mm 1.4P and didn't even get warm. Just make sure that you get good water cooling pressure. Run it fast enough so that enough water goes through the water pick up and cools the motor. If you run it slow or there is not enough waterflow then you are in danger of burning it out. I installed this on a Joysways Offshore Lite Deep Vee to replace the stock brushed motor. It was actually smaller than the original motor but used some epoxy putty to hold it in place and worked like a charm. Ran it on 2S 2200mAh 30C battery and you should have seen the speed.

hey i will tell you what i put in my nqd jet boat. one i put this motor, Turnigy Marine 120A Brushless Boat ESC,HXT500 6.2g / 0.6kg / .08sec Micro Servo, and lastly,HobbyKing®* ™*HK-GT2B 3CH 2.4GHz Transmitter and Receiver w/Rechargable Li-ion Battery. it did work but i did something to the receiver and it fried. i have a new one on the way and a new battery that i hope fits into a switch i have. here is the battery, Rhino 1750mAh 2S 7.4v 20C Lipoly Pack (AR Warehouse). when i get it in the boat and test it all i can show you all. :)
