If you take the motor apart, you'll see that there are three tabs that limit how far you can adjust the timing. Removing the tabs will allow infinite timing adjustment.
Oh ok. I have a 17.5 and 13.5 coming to play around with.

Thats a heap of timing. Would love to see the longevity at that timing as long as temps were kept under control

There is one issue with the modification to the sensor board. If you were to go to a race that motors were torn down like the Indoor Champs. That would make the sensor board illegal to use and until you put in an un-modified one you would not get the motor approved to use. Not an issue unless you are in those kind of situations.
I would like to see Turnigy release a approved board without the tabs though. Motor modifications made after ROAR approval must be submitted to them for approval.

I ordered a killshot 21.5 with high rpm stator this morning. Will be interesting to see how they compare.

Had my first run tonight with full timing and fdr of 3.95. Like others have said super torquey motor and i think it was still under geared as air temp was 27c (80f) and after a 2-3 min run the motor was only at 38c (100f) So some more top end wouldnt hurt as it was reaching max speed 1/2 way down main straight. Have spurs and pinions ready to try 3.85 and 3.9 fdr

I ran my 21.5 at a touch less than the 50*. Without a fan or heatsink.... It scooted pretty good but the motor started getting soft and slowed. Temped at 150*F. Backed the timing down to the last timing mark and temps were fine and it was a tad quicker than the previous MAX I could set it to (before grinding off the 3 tabs on sensor board), which is half a tick back from the last timing mark. Maxed around 120-130*F which is great. I'm at minimum weight and didn't want to add a heatsink or fan for now and be overweight, it's the cool So. Cal. winter so that helps a lot. In the summer I'll likely add a heatsink and use less Shoe Goo on the body to stay at minimum weight.

Still a great motor

I just got a Trackstar 17.5 motor and a friend kindly let me barrow sky rc motor tester to check the basics. The sensor board I got turned pretty consistent per pole timing reading. Only off by 2 degrees from the highest to lowest. The timing max out at 40 timing which confirms with my physical comparison with the reedy motor. Kv at 40 timing is 2380. I have never tested another motor I have, so I can't say about how good the KV is. The rotor do feel stronger compared to the old silver ones. One of the problem I have with the old one is the stator do not fit tightly against the casing which will cause vibration of stator during operation. The Red one seems to fit much tighter. Will do some track test afterwards. The old silver one do not compare to my R1 normal version in terms of both torque and top end as proven by my testing at TQRC. I can turn consistently between .1 faster per lap with R1. I will test the new red one soon. I do have good expectation for the new one since they do have stronger rotor and better fitting stator now.

I tested my 13.5t motor with the motor timing feature on the gforce esc software and it showed that maxed out was 39 degrees several times. i thought about just barely grinding the tabs so i can hit 40 degree or maybe a little more. ive read that the reedy motors that are almost identical to these really wake up at 40 degrees. running this in an offroad truck tho.

Tested TS1900 and 2400 motor with HW Xerun 150A ESC on different timings on 4S and 1900 also on 6S. They are delta would, so adding timing is little bit tricky.

I tested about 20 other motors... so apples to apples.

TS1900 compared to Tekin 1900 4030 and Viper VF8 1.9 :


TS1900 is also the same as Hacker 1900 V1:


TS2400 is actually more of 2675 and thus hotter than 2650 Tekin (also Delta):


TS1900 on 4S ... run 0 timing
TS2400 on 4S ... run 15 timing
TS1900 on 6S (yes!) ... run 11.25 timing

More in about a month

My ts 21.5 is coming off the track at 120f after 5 minutes running 3.2 gear ratio and 2.5 marks from max timing, on a 120'x75' asphalt track. No one pulls on me down the straight but I dont seem to have the pull in the infield when compared to a fellow racer running muchmore fleta 21.5 motor. Any suggestions ?

Has anyone ever replaced the bearings in this motor? I have pulled the front bearing out of this motor to check the size but the rear bearing is built into the sensor board assembly. Does anyone have any idea how you would get that bearing out? I would like to replace them with ceramics and see if I see a performance gain.

did an interesting comparison between my 400 pack 17.5 trackstar motor and 25 pack 17.5 D4 short stack at last nights local practice. My trackstar has been modified to get a bit more timing out of it. Stock max timing was 36 degrees. On a dyno, it made 10% more torque than the D4, but had a KV that was 10% lower with 36 degrees timing, compared to the 44 degrees timing that the D4 had. I have not had the trackstar dyno'd since upping the timing. I assume that the timing is at around 45 degrees now.

With no other changes to the car, and with the 4.59 FDR that I ran with the D4, the trackstar was about 0.15s slower than the D4. I went up two teeth on the pinion to get a 4.36 fdr and hit the track again, and ran faster than I had run wit the D4.

I also measured the stator in both motors. The trackstar stator is only 0.39mm longer than the short stack D4. Interesting.

These have been great for me. I quit buying any other motors for 1/10 scale onroad racing. After running just as fast as any other motor I have and had and NO reliability problems, I have to recommend them to anyone who wants to be competitive and save a few bucks.

Starting to wonder if my Trackstar is a lemon? Racing in the 21.5 blinky tourer class its often the slowest car on the straight but I have it geared for top speed (42 pinion and 60 spur) It gets the temperature to a comfortable 60-70c in a 6m race and I have it at almost maximum timing. Yet some cars just nail it with ease on the straight. 1 or 2 are only a fraction faster but the top cars often just fly past it... Its low end power is good and will easily spin out if I give it to much stick, just the top speed is disappointing.
I have another Trackstar 13.5 I race occasionally and it has loads of torque and a good top speed, only a fraction slower than the $120+ motors and that's with stock timing.

How long is the straight on your track, and what class are you running in?
