ran a whole TC season on asphalt with a D3.5 13.5 blink w/ track temps in ranges of 120 - 130deg. After 8 min I end up at 185 deg every heat. I feel no lost in power.

Has anyone modified the endbell to get more mechanical timing for blinky class ?

Default Within Spec?

With all the talk about the straight away speed these motors have, it still makes me question if they are within Roar specs? I know flame away but if they are out of spec to get the speed (I do not know if they are or are not!) then should they be allowed even at the club level? Again not saying they should or shouldn't just posing the question.

There is no need to do this. You may not even need full timing for Blinky. Every motor design has point where more timing will not make you go faster just make more heat.

Reedy Sonic Spec Motors run well at full timing (50deg).
Thunder Power Z3R run best at 30-35 deg (Max is 50).
Trinity D3.5's run best at 10-15 deg (which is really 40-45).

Just got one these for 17.5 blinky class and for some reason I 'm having a tough time turning up the timing on this motor... just saw the post about the "modifiying the end bell" I havent ran the motor yet but all I can turn is 2 notches from the max.. anyone else had this problem?

Never went above 80 deg C and it still died. Maybe its good for blinky....
Some updates...

Turned out that the shim on the rotor at the sensor end dissapeared. I believe it broke from the high revs and flew out the vent holes. This caused the magnet to rub against the sensors which causes wrong signals sent to the esc. Replaced it and tested it and it now runs fine, so far.

Ran against some other fellas last weekend and performance was on par with other motors. Was running with a Hobbywing V2.1 esc and the setting was:

Endbell timing: +1
Boost: 50
Boost accel: 200rpm/degree
Turbo: 20
Turbo accel: 18
Fdr: 6.4
Temp: 85C (Ambient 35C)

Power was consistent throughout 5 min but track time was limited and I believe some further tests would yield better results.

Will update further at a later time....

Mine is noticeably faster than the other cars on the straight. I have to be careful not to rear end the other cars in the 17.5 blinky class. But my Trackstar motors are running great. I have four of them now. I have two 13.5s for some short course trucks I'm building. I also ordered a 1/8 scale Trackstar for a truggy I'm building. I'm sold on these motors. My club doesn't seem to care at all. I'm going to run them!

And probably won't ever be considering the legal issues surrounding the "track star" name.

HobbyKing just needs to prove a sufficient number of motors have been imported into the US and that the motors meet the Spec class and Mod design requirements.

As far as the name I am sure they can have the next batch laser etched with some other name and get that approved.

I emailed HobbyKing and asked them to submit the motor for approval. You guys should do the same.

Turnigy or whoever owns the motors probably won't pay the fees to have it ROAR approved.

From what was posted in the D3 discussions, its a couple of grand for the approval.
Thats a lot of $35 motors.

That also depends on the volume they sell to the US, along with requests from people that have bought the motor.
Certain models of the Turnigy, Turnigy Nano Tech and Zippy Flightmax Lipo battery packs have ROAR approval.

And I'm very happy with my Turnigy Trackstar motor (silver can), it gives great performance and doesn't fade when it heats up like other motors do.

Cheers
Rob.

I have a feeling these Trackstar motors probably wouldn't pass Roar inspection, just like the D3.5. That's why they are so fast.
