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.
Numero d magneti del rotore. Da non confondere con i denti dello statore.
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..
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
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.
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
Installed this motor today. First of will say it is nicely made, finish is good, looks nice. Put it in a losi xxx-t. The motor runs well, however I have gone up 4 teeth on pinion to get the same speed as the 3650 3900kv tacon that it replaced and noticeably slower than a novak 10.5 with same gearing (which is rated at 4200kv so a little difference is expected) This is the only reason for the 4 crown overall. Initially used a mamba max esc to compare back to back, and get the gearing for equal speed. No noticeable cogging, smooth powerband, maybe not as powerful as the tacon of same rating, but no temp issues, and ran well. Final installation was with the new hobbyking sensored 35a esc. Again very smooth on takeoff, motor & esc stayed cool. Ran up and down the road a few minutes on 3s just to see how it handled it, which it did fine even though not rated for that. Ran 2 heats and a main tonight with the combo and very pleased. If it had to do over again I would have maybe gotten a higher kv motor, but with gearing suits me fine. Overall its a great buy that can't be beat for the money.

Just received my oder today, I bought this for my drift car.
Nice motor, smooth action, but no sensor wire and no manual included. And I think it's a bit lower kv, than 3900. But overall good quality for money, recommended.

Good Product. its nice to have venting holes and lots of screw holes options.
Too bad it is only 2 poles.
