We were able to run 38 degrees of timing (at the 38 mark) because of the crazy traction at Tamiya. The motor does feel like it has built in timing into it but not sure how much. I usually run the motor at 28 degrees of timing for medium grip on a medium sized track and it feels good. Good punch and rpm.

Finally got the motor to run really well in a 13.5 12th scale. It is 2 tenths faster than my D3.5
30 deg timing on the end bell with a 70-72mm roll out. Crazy different I know, but this motor likes to rev a lot.
For those of you running sedan, I would try 40 deg of timing and start gearing at 5.0-5.1. Trust me, this will make the motor really wake up. I think we have all been over gearing and been out of the power band creating excessive heat and fade.

I'm quite amazed how much these motors rev. Tachometer test was 40% higher rpm than my rpm stator and rotor trinity killshot. The killshot wasn't a dud either. Will get to see how it performs on the track tomorrow. I've adjusted my ratio to accommodate as I assume the motor makes less torque. Was also very impressed with build quality

I've been keeping my motor to 50 deg Celsius or less, 13.5 fdr 4.9 36deg timing.
I know some of my others motors can got to 90deg no probs, but what is a safe temp for this motor? Would like to try 38 deg timing or even 40, but seeing as these motors are hard to get, I don't wanna blow it!
I need slightly more top end, should I increase timing up to 40deg? Or go to the next bigger sized pinion?
With 4.9 fdr @ 36 timing, my car was a rocket out of corners and on the straight was only very very slightly pulled away from by the fastest car!
No one beloved my car was in blinky mode!
This motor is insane !
Oh yeah, my other motors are D3.5 & killshot!

If the motor has 30 degrees inbuilt then in then shouldn't the motor only be set to a max of 30 deg timing. Given a motor can only have a max of 60 degrees in total?

Have you tried lower roll outs? I have been running 13.5 blinky with good success on letting the motor rev. Typically I have been between 70 and 72 roll out with 25-30 degrees of timing.
On Thursday, I tried 72 with 25' and 30' and there was a little more fade at the end of the run, with 70 roll out and 30', I seemed to have the best fast lap and least amount of drop off. Only about .18 seconds over a run. Fast lap was 9.104 and second to last lap was a 9.289.
I had run the motor with a more conventional D3.5 roll out at around 80-84 and the hot laps were ok, but the motor felt low on punch and it would drop off 0.3-0.5 tenths over a run.
I am yet to try the 17.5 motor so far, but if it behaves anything like the 13.5, I would think that a roll out of around 92-94 would be good? Have you had a chance to try something like this? Any thoughts?
