I have a 13.5 Turnigy TrackStar, which I am using in a touring car.
Build quality is pretty good. The internal bearings are packed with really stiff grease, so need flushing out and relubing with a light oil.
When I first got it it was really fast. Competetive with anything else at our club. It also runs very cool. Much cooler than the X12 or SP/hobbywing motors at the same ESC settings.
However, after a couple of meetings, it seemed to "go off".
It feels like the timing ramp isn't being applied quickly enough, and when the turbo comes in it seems to take ages to wind up.
This was running on a Tekin RS Pro.
I swapped it over to use a Hobbywing Extreme Stock ESC, and it feels a little better, but still reacts slowly to the ESC timing inputs.
As such, I'm now at a disadvantage on the track, as I lose a meter or more when acccelerating out of a corner.
It wasn't like this when I first got it, so something has changed or broken. there is nothing inside which is obviously at fault.
No settings were changed on the ESC to provoke the behaviour.
three different sensor cables were tried.
In summary, when I got it it seemed like a fantastic bargain. Genuinely competetive with anything else out there. (I bought it to replace an X12 and was not dissapointed).
Now, I have a motor which works, but is just a fraction off the pace for competetive racing, with no easy way to figure out what the problem is.
I'm not sure wheter to try another one, or bite the bullet and get another LRP/Noram.
