absolutely fine off road in wet muddy tracks and on gravel, the vents are only to cool te stator winding's ,there are no moving parts exposed , just blow it out when it gets crud in the vents, periodically strip and clean the motor and oil the bearings every time it gets run in the wet, had mine quite a few months in my of road 2wd buggy and its been superb.
does anybody know what size bearings this motor uses? i have bad bearings in mine and need to have the bearing sizes to order replacements from boca bearings because i cant replacements for it here on hobbykings site
Looking to buy this motor. Will it work fine with a sensored 35amp esc, since the motor only pushes out 28amps? Or would I be better off buying a 45amp esc?
I'd personally go with the 45 amp to be safe. I'm running it in a Tamiya TB-03 touring car at the moment and can get it to peak in the high 30 amp range pretty easily. 35 amp would probably technically work, just ensure you have good cooling. 45 amp ESC's are only a few bucks more though so I'd strongly recommend that.
what is the best esc for this i just bought one its gnna be for my sc10 sct 2wd ,i look around and i'm confused theres a 50A ,60A even a 120A ,please any suggestion please ,thank you
This motor only draws a max of 28amps so you do not need a high amp ESC otherwise you will not get a good linear throttle function.Take a look at the HobbyKing X-Car 45A Brushless Car ESC Sensored/Sensorless,think that will be more than adequate for this motor.
ok thanks that was a quick reply ,one more thing do i need a programmable card for this esc and what a bout a "turnigy" esc a closer combo for trackstar 17.5T please,thank you
oh! ok what i'm trying to say since its a "turnigy" motor i want it a turnigy esc too...anyway thank you for your time i will searching for the programmble card & the hobbyking esc,thank you
I disagree on not needing a high amp esc. Yes, it's not required, but there's not a downside to running a high amp esc. You would be fine with the 45 amp esc mentioned, but not for the reason stated. ESC's work by switching on and off full power thousands of times per second, but the amp rating has to do with how much current the esc can handle running through it, not how much it forces the motor to use. because of that, the throttle curve is not effected.
you still don't need a high amp esc, but there is no real negative to running one with a low amp motor other than saving money and weight.

I would not recommend running it on 3S. The motor is rated at 7,4V(2S). It will work on 11,1V(3S) for a while but will most definitely overheat easily. If you make sure it has ample cooling you should be able to run short periods at a time but the motor is not designed for voltages that high so it will probably wear out quite quickly because it will take heavier amperage that it was designed for.
try to go for "low Turn (T) values" (high Kv values) like* 10T will be much more faster than 17.5T, a 4T motor will be fast as hell :) Low T means more speed, less torque..
For Kv value, more kv means more speed,less torque. For example the upper one is not a fast motor, its suitable for short course/monster truck.
If using stock or zero timing ESC you need to use low gear ratio and adjust it to suit your track. For track that has a lot of sharp turn you may need to use a slightly high ration say 4.0. However if the track has more long straight then you need the speed which means low ratio. 3.5
if you cant run any timing you need to change your gearing then i have a sc10 81/24 on a good size indoor track i also run a fan over my motor to keep things cool
Yes this motor is for 1/10 scale and suitable for touring car. I am using this motor on my Tamiya TA05 touring using turbo ESC. I am very happy with the performance.
Neil, this motor seems to be just like the reedy sonic motors. I suspect the sensor board for reedy sonic to be a direct fit.

Bought this and a 10.5 to "test". So far so good. Overall quality looks good. Disassembled and checked the internals. Center solder post was a bit loose so epoxied it w/no issues. Bearings look good but I'll continue to monitor. Rain about 5 packs in it mounted to my B4.1 geared 33/75 blinky on Viper VTX10. Very smooth and stays super cool. Very impressed so far.

So far I'm impressed by this motor. I'm running the 17.5T in 2wdSCT MOD and got 2nd place in the A-Main tonight. I have gotten pretty high post race temps a few times and the motor is still going strong. Very happy thus far with my purchase and will probably pick a couple more, one for my son's XXX-SCT and one as a backup.

Just both this motor the test if I could handle the speed of the 17.5T series. It seems to do well. I tested it on an old Xray M01, with a gear ratio around 5.81. After a 20min run with 2S lipo and maximum timing on the motor, the motor had a temp. of around 50°C, which is ok.

I like this motor a lot. Put in my sons XXX-SCT geared at 82/24 and advanced the timing on motor 2 notchs. It flys! Good punch and speed, about 130 degrees F after five minutes. All this run on old Novak Havok pro and turnigy 40C 5000 battery. For a US off road racer this will not disappoint.

I've used a TrackStar 17.5 last sunday, in my WRC F1.
I took the second best lap time in the 17.5 class, racing carpet indoor. I miss the best lap by 0.031 second.
Honestly speaking, I'm extremely happy about it.
