I have a 1/4 Dirt Bike to upgrade from the stock motor could I use S2848-3900 Brushless Inrunner 3900kv (11.5T) this motor is a little smaller but more powerful and would the Turnigy TrackStar 1/10th Scale 60A Car ESC Version 2 work good with this motor???
Hi,
First you have to check the space available for your motor (you can check your old motor to see what type it is, for ex. 380).
Then you can choose a size for your brushless motor, with an ESC capable to deliver - at least - the max amp. of the motor (for ex. you have to choose at least an 45A ESC for a 40A motor).
Super happy with this motor in my Slash 1/16. Gearing is 25T pinion, stock spur. I paired it with the Turnigy 45A Car ESC, and 2 turnigy Nanotech 1400mAh 3s LIPOSs running parallel, and has a lot of power. ESC stays nice and cool, and I get upwards of 50 min of run time bashing. After 35 min of hard driving motor temps were 128f, ESC was 100f and LIPOs were 70f. Ambient temp was 53f.
It has so much more power than I need, I set motor timing to 0, punch to "med-low". Absolutely no cogging, and runs smooth and cool. The little truck will hit 35mph to 45mph depending on weight (with 2 batteries, or just one) and timing settings.
Only thing left to do is seal the diffs and add 50K wt oil, so the isnt so susceptible to torque roll. Very Happy with this motor.
edit: when I did speed runs the motor hit 158f, so if you want to do non stop speed runs, you should gear down to 22T - 23T. And do the same during the summer.
Also pairing it with the Turnigy 45A Car ESC, its just plug and play, and just need to install a battery plug.
I use these motor on my converted 1/16 nitro buggy with 60A ESC and 2S 1.7 lipo it run great! but when i try 3S 2100 lipo, it has to much power and speed for the buggy to handle, I'm worry about the diff and trans gears...
Hi guys! has anyone mounted one of these on a HET 6904 EDF unit or similar unit??? I would like to know an AMP draw estimate as I still don't have a watt/amp meter. Thanx.
Hello, I have used this motor on my Weapon 400 pylon racer and it is great :) Using a Turnigy Nano Tech 1300MAh 45-90c, 60amp ESC, 4.1 X 4.1 TGS Sport Prop, 30mm X 30mm aluminum spinner :) Flys around the 160mph haha Hope that helps Joao.
ok Didn't know it would fit. do you know how many amps you pull on 3s? By Thinkin about this motor I remember a review here in the reviewsection where someone claimes he uses 4s in a 68mm fan.
This motor does not match your plane. It has too high Kv to be usefull on the sky climber. To be able to run this with a prop, the prop should not be bigger then 4,5 to 5" diameter or it will burn!
hey guys, im running this motor with a Hobby King 35A Sensored/Sensorless Car ESC (1:10/1:12)and its not working?!
the esc is telling me the motor is sensored?!
thanks
hi, with 2s lipo it would work, but with 3s u need a better esc. (motor can use up to 41 amps at high voltage). Anyway, i dont recommend it on a plane, as it's quite heavy.
A car doesn't quite have the same airflow as an EDF, plus an added heatsink can make a massive difference. I asked about 4S because voltage doesn't really bother motors as much as higher amperage. Keeping it around 500W but on 4S instead of 3S would mean much lower amp draw and longer flight times 8) A nice lightly loaded 70mm fan like a Changesun could probably work well with this motor on 4S. Seems weird and a waste to me to have a long can motor (extra weight) like this only rated to 3S and 41amps.
I have tried this motor together with a Wemotec Minifan and the scale says 1200g thrust. My flight were about 2 minutes and I charged 1200mAh into the 4s 2650mAh Lipo. So in average 36A were flown. I hope this help.
Thanks Gregor, I'm a little surprised that's all the thrust you got with this KV motor on a Minifan with 4S, wouldv'e expected around 1.5-1.7kg. What condition and 'C' rating was the battery?
Either did I! I used a 4s 2,65Ah Lipo with 35C and I a 4s 5Ah Lipo with 25C. Both nearly the same results. But this configuration is much better than HET 2W with 3s Lipo.
Use it in a Revo VXL which i bought without electronics and runs nice on 2S and 3S with the 23t Pinion gear and the 30A HK ESC. Bigger gears are ordered to test the performance with these
esse motor é ferra pode usar que não vai se arrepender.

Just recieved this motor. It's extremely well made. The back bearing is sealed off. The rear cap is not glued but pinned with screws so no chance of popping off like other motots. The shaft is slotted and is 3.17mm as stated. True Diameter is 27.80mm and true lenght is 48.15mm. Screw spacing is exactly as stated.
Excellent use of motor Turnigy TrackStar 1/10th Scale 60A Car ESC

Hi all:
This is a verrrrrry good motor. Tested with a 68mm EDF 5 blade from haoye, with a 4S 2200mAh 45C B grade lipo, and peaked 960Watts, at 64 amps and an incredible 1.58 Kgrs of thrust. Motor was quite hot after 2 mins of testing (60ºC), but all seems OK. It is much more powerful than HXT 2835 3900,that only delivers 600Watts with the same setup. Motor seems very well made, and very well balanced.
