yes you can

Take a look at the Turnigy Trackstar 150A Part#TTS-150A or the Turnigy 160A Part#9192000001,both would be ideal.

ust been restocked but all sold again 31/01/13

 paweldededed 480 points

yes it will work fine make sure u use lipo of 4 cells , i dont have any issue with this motor so far even run on 5s lipos and all is fine make sure u have good cooling and start with small pinion and see how it goes , check temps time to time well done motor worth the money

 zenzen 52 points

thank you! go on my ve8!!!

 paweldededed 480 points

will work well on 4s lipos just start with lower pinion first and see how is the temps, i have this geared 12/50 in my truggy and is working fine , have installed 2 pc 12v fans connected to balance port of the lipo to keep motor temp down in the summer overall is not bad motor for the money u pay cheers

 Luiz 42 points

Good ideia my friend. Did you put a separate battery for the fans?or did you connect in to the receiver?

 paweldededed 480 points

hi i connect it directly to balance wire from my 4s lipo the fan is ys-tech 12v 40mm diameter give u good cooling cheers

 paweldededed 480 points

there are some guys thet run this on 5s lipo in my club and i didnt see that they have any issue with motor make sure u put smaller pinion u can to start with and see temps after runs if is below 60 celcius you'll be fine make sure motor got some cooling put it a fan as i did 12v PC fan pluged to balance wire directly to cool it dowm motor i run this on 4s 12/50 in my truggy with fan installed hope thats help cheers

This motor is of the declared parameters may work a maximum of 14.8 4S ie wills, the use of battery 5S priveesti can damage the coil, the engine burns, it is better not to risk)

 paweldededed 480 points

tested today on termac with 1/8 scale buggy hyper 9e geared 15/40 lipo turnigy nanotech 4s1p 35C 4000mah , max 72amps peak, 1030watts, motor temp after 10min run 56celcius, outside temperature 21celcius all under body with 12v pc fun connect it ti balance wire directly , esc is mamba max pro castle temp after run 50celcius, Overall this motor is great quality compared to castle creation honestly but u pay lot less opened to see inside my one has japan make bearings high speed one worth every dollar hanks hobbyking u r king!!!!

There is no difference in terms of performance, model number is to signify car or boat application possibility.

 paweldededed 480 points

2.5mm same as castle creation cheers

Physical size and weight is the same. Run this on 4s and there will be no noticeable difference between leopard 4074. However, the specs for Leopard claims it can handle 6s, this one is not.

 chakal 892 points

Better get 150A HK esc.

 paweldededed 480 points

it wil work on 120A esc but make sure you test it on watt meter to not burn esc i have this myself on 120A mamba max pro and is working perfect on 4s lipos cheers

 fred0000 104 points

i've only tested at 5s, I think it would be ok at 6s just watch temps and gearing.

 zenzen 52 points

5s with 150a esc on st-1 brushless is very good!!!!! not hot( i have a fan on it)

 Benjamin 1 points

I have tested this motor with 6s , it work very well! with 150A of course. With 6s this motor have a great powerfull! i think , it's a same of leopard 2000 *)

 fred0000 104 points

standard mounting specs (same a tekin t8 and any other 1/8 motor, I can measure when I get home if required.

 Shuz199 40 points

I am curious about the mounting hole distance too. Could you take the time to measure if you get a chance? Thanks.

 fred0000 104 points

much larger, 540 is 36mm x about 50mm, this is 40mm x 74mm

 iSkate 1 points

But are the mounting holes set up the same as on a 540 Mamba Max motor?

 fred0000 104 points

great motor, I use it in my losi 8ight-e, and losi 8ight-t (1/8 electric buggy and truggy)

 paweldededed 480 points

i run this in my rc8t-e is workin well on 4s lipos just start with lower pinion first and see how is the temps, i have this geared 12/50 in my truggy and is working fine , have installed 2 pc 12v fans connected to balance port of the lipo to keep motor temp down in the summer overall is not bad motor for the money u pay cheers

 zenzen 52 points

Good with 5s and a fan on it on truggy st-1.i wait for the 1/8 turnigy 2100kv. but better with the 2000kv leopard.

 XTRA40 45 points

great motor i have it in my hongnor x2 truggy great strenkt progranm card wil com but you can set up your esc whith out the card so no problem there

 Polardegos 54 points

It means that the moving parts of the engine are spinning inside the stationary motor can. The magnets are mounted on the shaft in the center of the motor, and spin inside the stators. Outrunner is the opposite, the moving parts are on the outside, that is the can with magnets are spinning around the stator.

Yes off course you can use it... good motor this one . i have it. second option would be KD36-74-09XL 1900kv Brushless Inrunner my 2 cents *)

 shanefletch 1 points

I run this motor in my eRevo with a 150A turnigy Trackstar with 2x 2S 5000mAh lipos in series for 4S. It's geared 18/56 with stock wheels and tires, no overheating issues no matter where I run it.

 bruno 3 points

no! normally, and i think thats allways, the sensored motors have a other conector a part of the trifasical wires. see the diference searching and comparing beetween two kinds of motors. you can see this difference seeing the contrary part of the shaft.

 Jeroen 2 points

Tx bruno, I figured that, but with the pictures here one never really knows... Ordered it for my summit, will see how it goes in low gear when crawling - worried bit about cogging. Have to try.

 shanefletch 1 points

I run this in my 1/10 eRevo with a 150A turnigy ESC. Geared 18/56, there's VERY minimal cogging. I can crawl with it no hassles.

 Zahid Rasheed 70 points

More magnet poles means more switching in the esc as the polarity changes more often for a single revolution of the rotor. That can create extra heat in the esc but good quality esc's can handle that. The advantage is that the higher pole count motor will feel "smoother" in the torque department and has a little natural braking as well off throttle. my 2 cents *)

 scarletboa 349 points

4 pole motors are generally much higher in torque and run much cooler than 2 pole motors. this is due to a much better design that gives much higher efficiency. the difference in esc temps is small with 4 pole, and that is only because you can get more power out of the motor compared to a similar sized 2 pole.

 fred0000 104 points

Yes 4mm. Males installed on motor. And 3 female ends in the box.

 XTRA40 45 points

I can not see the difrence to But i have it in my mugen truggy mbx6T and it has loads of tork and good speed on a 4 cel lipo It becoms good warm but not to warm so i do not need to cool it extra

 wrapter 1 points

It mostly capable of handling 6s battery ,i believe HK as made a typo in the specs it has to be 25v.

 fred0000 104 points

should be fine on 6s, just watch your temps.
I run mine on 4s only, 1/8 buggy class only alows 4s at my club

 bongsky007 92 points

This is a 4 pole motor just like leopard motor and almost the same specifications..

 sampit 6 points

Great new,on that note I have just ordered a 4082 1600kv for my Hydro Marine agitator cat
these will sell in lorry loads at this price

 elgusanobi2008 65 points

fijese en la ficha tecnica,dice 4 polos

 Sheepy 24 points

The spec states that its a 4 pole motor. Looks like a good thing. Time will tell on the durability.

 the savy fluxer 24 points

pretty much the same price as the tacon from www.link

 the savy fluxer 24 points

this is the perfect motor for the pursuit or the genisis.

 Krunoslav 15 points

This are 4 pole. Think they are like this one www.link HK?

 elgusanobi2008 65 points

esto es un motor de 4 polos ,2 polos positivos y 2 polos negativos , mí*nimo se necesita 2 polos para poder girar un motor elé*ctrico , cuanto mas polos tiene un motor, mas suave es la potencia inicial de arranque

 Norway93 53 points

Should be perfect for 1/8 monster trucks, savage flux ect:-D

 elgusanobi2008 65 points

si si ,es lo mejor que hay , 2000kv en 5s es igual a 100kh de velocidad en mi hpi hotbodies escala 1/8 y es mas barato que un leopard
