Slow 21.5 speed..

If the temp of the motor is less than 70c, then I'd increase the rollout (decrease fdr).
Some of the Sydney boys run between 2.9 and 2.7 fdr without any overheating and quite good speed.
The motor isn't a rev motor so it can handle a tall rollout. Max motor timing is a must.
Just watch temps.

Generally the trackstar's are okay - they aren't the best but have some pace and with good enough driving, could possibly keep up with more expensive motors. I would say aim for lap times rather than top speed. Some people gear the shit out of their cars but their infield speed suffers greatly.
Play around with the gearing a bit more and try to run your motor between 60-70 deg celcius. Any hotter and it won't be good for the motor, any cooler and you won't be maximising your performance. With regard to spurs, maybe use some aftermarket ones? I'm not familiar with Sakura but I'm assuming they are just standard spurs? (So that you can use RW Racing spurs, etc)

we run right down to 2.8/2.9 blinky 21.5 but make sure temps are in check.
Trackstar/turnigy motors as good as anything more expensive so could be a bad one so would pay to try another one to eliminate.

Coopz what lap times where you getting Friday night?
at what part of the straight can you hear your motor max its rpm ?

I didn't race Friday, but I was there for a hour before doing practise laps, best was only a 17.8, partly attributed to some handling issues I inflicted on myself and I wasn't running any tyre compound. The motor seemed to peak halfway down the straight and the other 21.5 cars were easily outpacing it.

Your problem could well be your motor however the straight is only about 2 seconds of the lap time so it is important to get the rest of the track right.
You will want to get you car handling well for the midsection and the fast sweepers. If your ever at the track and see Billy there go talk to him about Sakura S Zero setups, he was quite quick when he ran that car and had found a setup that suited that track.
As for top speed down the straight gearing will be the key. When do you plan to go there again ?

Boy I heard that a lot with my MBA (much bitched about) Boss motor. But you have to have speed to carry into a turn. Sometimes it is the motor. After replacing the sensor board, finding the timing label was wrong (instead of 45 degrees timing it was actually 58), I got the motor working fine and the same setup was very competitive.

One other thing that helped, I found after I got my motor working well on the straights when I bought a new radio. My old TX/RX I had used on my off road truck and it still had a lot of expo on the throttle. I went to a linear throttle response and the acceleration out of the turns improved too. DAAAAH
#26
yeah expo is fine for offroad where traction is low. but for onroad i allway run linear. i used to have some expo but i have gone away from it. when were you coming up this way? to the seattle area?

PS the motor may not be the ROAR spec version since they appear to be from down under.
