you could get this motor and a pinion to suit for cheep

Sure you can!

this is a great engine but is not suitable fo offroad because it has an open cover, look for something with a closed cover

buy one of 13.5 motor its just as good

Can i use them on my 1/10 scale monster truck?

Sorry, but this motor needs to run the sensor control. It can not be excluded. This motor is not suited to off-road due to the air, not waterproof and dust would suffer.

Yes, it works without sensor cable, I tried, not as smoooth, as in sensored mode, but works fine.

it is 2 poles. not 6

Hi! There's no need to cover the holes. It will just get warmer if you do. M.E.

This inrunner an engine, not suitable to off-road. Usually an engine inrunner and more prone to heat, because the track used always 80 / 90pcnt accelerator. For this he needs "more air" cooling. Instead outrunner motor, less need for air because less stressed at high speeds, but on the contrary, must be protected from dust and water. If you put a motor inrunner, a model of off-road, I do not think you made ??a purchase a success. At this point you should tapare holes. Lascuia everything as is.

You can cover the holes but you have to add cooling fan on it...

Numero d magneti del rotore. Da non confondere con i denti dello statore. Basta contarli. Molti inrunner hanno però un solo magnete con diverse coppie di magnetizzazione, per contarle basta testare la circonferenza con un magnetino di prova: una attrazione = 1polo, una repulsione = un altro polo ecc..

no. it means that it is a 2 pole motor. a 6 poles motor snaps at 18 locations.

Arrived today. Going to test tomorrow. Looks good so far

ran mine for 10min or so on 3s just to see how it would do, had no problems at all temps perfectly in range. Motor seems a little lower kv than 3900 compared to my others, but does a good job pushing a 2wd slash around.

In cars and rare inrunner mount batteries with voltages above 7.4 V (2s LiPo) for the weight, very important on the track, driving in the the mixed. The speed is not everything if the machine then becomes difficult to ride. What is to be mounted on a car inrunner 3s if you can not even accelerate the car swerves? If you have purchased this engine for off-road, I tell you from experience that it is not suitable. Suffers much dust, and is not waterproof. So if it dies for overvolting, will die fro

dovrebbe essere un buon motore, potente e reattivo. Facci sapere come si comporta in pista.

 zanek 96 points

I don't think so. I think it is just a standard sensored brushless motor with not extra features, like this thermal overload.

The KV is the Inverse of "turns." That is, the higher the KV, the lower the turn. Mark me as the best answer! :)

 herratic 4 points

Best answer so far, haha. I do know the more Kv the more power, but I meant that I am used to compare motors by their number of turns. I'll never buy a motor just knowing the so called "kv". Thanks anyway.

 Tatiana 4 points

Agree, need to know turns and kV both

 rc2rc 80 points

Its 10 turns, i use the novak motor sheet all the info you need about kv to turns etc. So do i get your credits? :P

 Mav75 76 points

Turns are becoming irrelevant anyway. It's more accurate to measure a brushless by kv once the km is established. :)

 acbaldwi 7 points

actually looking at the novak sheet it is more like 11 turns... 10.5 turns would be 4200kv, and 13.5 turns would be 3300 kv... so it is in between those numbers... my guess is 11 turns....

Lately, we prefer to express the characteristics of the motor speed in KV (rev per unit of volts) instead of expressing the number of turns. This is because, not always the same number of turns, including several engines, bore the same result in terms of speed. The scale in turn is reduced to jumps of 0.5 turn (leaving little room for the accuracy of the description). Instead of stating the number of revs per unit volts of power, you can give a more accurate description of the actual performance
