dont remove them all the way. you might have to use pliers and use some kraft paper or construction paper or something to protect the aluminum from getting marred up. i had to a few times. some of them are very tight. the timing marks that are on the car are as far as the timing will go. its not much but i have found these motors to have alot of torque so i can gear them a little more than a regular motor. good luck.

Thanks Took a bit of effort but I managed to increase it by 20 degrees
Its getting up to 65c during longer runs, is that a bit hot?

65c is comfortable operating temp. If you're coming off around 75-80 then it might be getting a bit warm in there

I ran a brand new 21.5 red Trackstar in Outlaw VTA last weekend and just wanted to say it's quick. Pulled a Schurr Speed motor on the straight. hottest it got was 144*F measured by telemetry sensor zip tied to the top of the motor can. 2 other sessions were at 133*F. Motor timing is maxed out, about one half tick from full timing on the label. Does this sound about right? No fan or heat sink.

I also added two drops of 3-in-1 oil to the front bearing (pinion end) out of the box, and it the rotor noticeably moved quicker and smoother.

Best $30 purchase I've made in a long while.

put a wtf fan on it and it runs even cooler. i always run a fan. @7.4v wired direct to esc battery wires so when its plugged in the fan runs. my 21.5's ran at around 130F outside in hot weather 80-90+ air temps. these are good motors. now iim running a 17.5 and its only getting to 115 indoors on carpet. max timing.

These motors are a really good buy.
What fdr ratio are you running , pinion/spur sizes? Thanks

last summer i ran 21.5 vta. a good starting point is a 3.6 fdr. 88/48 is a good gear set to start with. if you need a little more go up to a 88/49 for a bit more speed. these motors have alot of torque.

Got to run my 21.5 and 17.5 motors on a bigger track this weekend. They definitely hold their own. No one pulled on my 21.5 car on the straight. I think it was the fastest car in its class down the straight. It looked to have less jam in the infield, but my punch setting is only at 10%.

I've been running it at about a 3.0 fdr and it was temping at 45c, very cool.
I'll try smaller pinion to allow the motor to rev more.

Thanks

What are good "blinky" esc's to run with the trackstar? I was wanting to run 17.5 short course class, the only motor i see is the red one. Is that the correct motor now thats roar legal? I would run it in a 2wd slash. So coming from a brushed motor what gearing would you recommend for a tight indoor clay track? Sorry for so many questions. Im a noob lol

I just bought 2 red 10.5 trackstars and installed into my 4wd buggies. Ratio is at 8.5. I find that when i hand push them they kind of cog. My team powers is very smooth. Also the motor seems abit noisy at low speed. Is this all normal.

Try moving them without pinion.
If you feel a strong magnetic field then it is normall that it seems that they "cog".
This also exlaines the "noisy" low speed running.
I got the silver can 10.5 Trackstars and they do the same at low speed.
When running at high speed it is gone.

Regards Roy

Has anyone ever ran one of these 17.5 or 21.5 with an LRP Flow ESC? How do they preform?

timing on both motors maxed out and both ran cool with lots of power and torque.
