It is resistant for 4S ?

Shonen (54%)
keep the motor under 40000rpm to avoid excessive heating and/or bearing failure.

somebody have told me that I should look for a .5 motor for buggy... for ex EZrun 8.5 'cas this 9T wouldn't be strong enough..... could you gusy help me with this? Is this motor good for the job, with a Turnigy 60A esc for ex?

WD479 (70%)
there is no big difference between 8.5 and 9T motors. This motor will work with turnigi60a esc.
I think this motor should be strong enough for models 1/10 and smaller even with 2s lipo.

I use this motor with turnigy 35a ESC, lipo 2s. The ESC running warm, the motor stays in about 60-75 ceusius. The 9t motor will works fine in 1/10 buggy, more kv than 9t the car stays a little out of control, 9t have a good balance.

Will this motor fit in a 1/10 2WD slash? Thanks, ive looked up dimensions but i wanted an opinion from someone who has tried it!!

Ivan13 (62%)
I tried running this in my SC10, and a friend of mine is using this on his Slash. No problems.

Alec (67%)
so it worked fine in your sc10? and did you use a 35A esc?

Ivan13 (62%)
I used the 35a Hobbywing esc in mine.It lacked power off the blocks. Ifyou use a 60a esc or higher,it should be fine. I am using HK's 100a 6.5t combo on mine now. Very very smooth and powerful.

Yes. I installed this into my Stampede with no problems. I'm running a v6.6 LiFeP04 battery and it rips. Can wheelie from a stand still and if you punch it and actualy control the wheelie, it pretty much hard to steer. :) It might be a bit much with a higher voltage battery, but for $30, how can you go wrong. Like others have said, this is actually a 380 motor not a 540. It's hot after 5-7 seconds of holding you finger on it after hard bashing. Is this to hot, I don't know.

I get more speed, I have a XSTR-pro, 03307 HSP Brushless ESC 75A, which supports 2S lipo, and the motor is 3300kv. With this motor will get more speed?. Thanks

Id like to know if this motor is sensored or sensorless. How about run it with the 60A Turnigy ESC?.Thanks.

afxdz (72%)
absolutely yes.

afxdz (72%)
and this is sensorless motor.

Black_Aypim (22%)
Sensorless. You can use even the 35A model with no problem.

Josef (75%)

Max speed is depend on your battery(Volt).
for example...4300KV*7.2V=30960rpm

Futaba (94%)
Max speed is about : 100km/h

Tyler (97%)
what is the diametre for the front mounting holes

Grzegorz (62%)
It's about 25-27mm, as for 540 motor size

ODmix (53%)
diameter of front mounting holes ins just 25mm!!

Sergey (43%)
11.1 volts work???

sietse (85%)
You can put any voltage on allmost any motor.
With this you control the max RPM of the motor.
This one is 4300KV, that means: 4300 rpm per Volt. So on 11.1 Volt it turn in theory without losses at 11.1x4300=47730 rpm. It depends on youre gearing and use how much amps you pull. You can use one motor with allmost the same power at 2 or 3 cells if you change the gearing accordingly.

Futaba (94%)
Yes it works, but you have to disconnect fun because it burndown over 8V!!!!!!!
