Guys are still playing around with some crazy settings that seem to work for them!
I would recommend starting 50 to 52* and a 4.2ish to start.
Guys have gone up to 60* with a 4.96 or the other way.. 44* and a 3.90
This new motor has much less rpm compared to the v2.. But be careful with the timing, the amp draw will jump up quickly above 50*. If you go high 50's to 60* make sure you start around a 4.9 to 5.0 that set up may not give the top end you'll need on a larger track.

I saw the 25.5 in a f1 Saturday. Had plenty of rip. Geared 36/92 and timed at 38* on a large carpet track.

Hi guys. I'm looking for a starting point for timing and rotor selection on a 17.5 V2 boosted sprint dirt oval. Any suggestions? Thanks!

Guys have gone 2 ways...

12.5 4 line with 16 to 18* or so in the motor and low timing in ESC and a higher RO
or...
12.3 3 line (Or F1 rotor) with 16 to 18* in the motor and higher ESC timing with a lower RO

The V2 is a higher RPM motor... with that said... on tracks 120 x 60 or so outside guys have run 44 to 48* with a 4.6 to 4.4
It will depend on flow, traction, and size of the track.

Was running some practice laps with my new 21.5 V3 for USGT yesterday and the motor was only coming off at 90 degrees. Motor didnít seem like it was working hard and seemed slow compared to my old V2. Just wanted to make sure I have FDR & timing right. Track is approximately 80x50, 50 degrees timing, 4.25 FDR. Any thoughts?

Mine really came alive at 60+ and 4.69 on a track layout only slightly bigger. Temps 126.

Hey guys, I'm running a XB2 carpet edition buggy which has a FDR 2.65. With a "The One" 17.5 (version 2), I'm running a 75/31 = 6.41 overall drive ratio. My question is, how do I know if the motor is "burnt out"? I'm running a fan and the motor just doesn't seem to heat up. I run on high bite carpet. Even when I set the timing to 50 or 55 degrees, I only get about 105F temp. And that's with me trying to find a hot spot with my temp gun. With this gear ratio, I feel like I don't have as much punch and doesn't seem as fast on the straights as other people's. My batteries are new Reedy 120C 7.6V 4900mah. I'm planning to take the motor out and put it back on my motor analyzer. The ootb result was 3163 kv @ 7.7volts, 24360 rpms, set at 46 degree timing and a 3.8amp draw. Other than me re-running the motor on the analyzer, is there any other to check if it's burnt out? Or any other suggestions? Thanks in advance.

Due to the high efficiency of these V3's temps are always low. We've noticed as of today's testing on high bite indoor clay that the motors are not too crazy about large spur gears. Recommend timing@ 49 to 51 degrees and use a 69 spur and see if you can squeezes 5.88 to 6.15 (all approx.) fdr. The sweet spot is illusive with the new motors, but when it's found they're quite good. Hope this helps.
