Dragonracing - I have a fan on my esc but not yet on the motor. Looks like I'll add that to the to do list.

Nego - did you source the timing board direct from speed passion? Might have to look into this feature.

John wallace2 - thanks for the heads up. Looks like I have a lot of testing to do with my fdr and motor timing. I had some regrets buying the sp motor but didn't realize I still have lots of tuning options before I move to another motor. Thanks again!

So I took the motor out of my car to try adjusting the timing. The only adjustment screws are on the pinion side of the can. I unscrewed the long screws and see how you can rotate the sensor side of the can. The problem now is that the long screws won't reset in the can after sliding the sensor side of the can towards the higher side of the timing. At this point I'm going to return the motor back to original setting and try to adjust timing on the esc, if that's possible.
I did not remove the esc wires from the A B C terminals on the motor so that's the only thing I might have missed in the process.

Anything else I should do?

Thanks...

Nevermind on the esc timing.. Justock club spec esc has permanent 0 timing. On to adjust gearing and purchase green & red timing boards for further testing.

The sensor port slides back and forth without unscrewing anything. Just friction keeps it in place. It doesn't move much, just a few mm. Not a great design, because it can move on it's own just from vibration and it's stupid to have to change the sensor board just to get a little more timing than what the movement in the slot allows. I used to have a SP motor for racing 13.5 boosted, a few years ago. I would jam a piece of servo tape to the left of the sensor port to keep it at 20 degrees. I bought a different brand after. The bullet connectors would often have a weak connection and cause cogging too. IMO it was one of the most poorly designed motors.

yellow(+30) or blue(+40) is more likely what you want. Honestly, I'd suggest a different motor entirely.

Timing on those are more traditional adjustment. Turning the endbell. Any are good. I have heard the wurks r1 motors are pretty dam fast.

Check out the turnigy trackstar 21.5. Standard adjustment, lots of power, roar approved, and only ~ $35!

All good choices mentioned above. I have a Team Powers plutonium v2 21.5. Its what most of the guys near me use for USGT and also for our Canadian VTA class. Very quick motors.

I would have to agree with this. I bought the 17.5 MMM and I think adjusting the timing on these motors is a hassle because you have to remove the motor from the motor mount to loosen the screws to adjust the timing board. If you want more timing then you need to purchase 30 or 40 timing boards that are $30 each. When you include the cost of these extra timing boards you're better off spending that money on a different motor. In the end I decided to switch to a Reedy or Orca motor which already has all the timing you would need built in.
