I just installed mine but in my WGT. I was told that the timing sweet spot range was in the 40* mark. Gearing you will have to figure out on your own. Start with what other people are gearing at in 12th scale 13.5 at your track. I test mine on Sunday so I will report back after that.

I hope they told you there is a big difference between the 40* mark on the can and 40* of overall timing.

If you're running the motor on the 40* mark on the can, your motor will get stupid hot. That's like the equivalent to running 70* degrees of overall timing.

You want to be running 40* overall timing, you're probably looking at 0~10* on the can.

Thanks for that info! I was wondering why so much timing on can when premium 17.5 is best at 0 or 5 degrees on can in 12th scale.

Yup. According to a Motolizer, the average timing at 0* physical timing amount to 31* on the Motolizer. So this sounds spot on.

I think the question that needs to be raised here is whether or not timing marks are equivalent on the V7 versus the V9 motors (i.e., 30 degrees is "built in" on both versions). Can anyone from R1 chime in ???

Need a new motor, how would a 21.5 Ultra Premium compare to a 21.5 D4 Maxzilla ? For Outlaw VTA, on asphalt with the HPI treaded tire.

You have measured the v9 motor? Interesting!

My v9 came set at 30 on the can. Should I just leave it there?

V9 13.5 1/12 small technical track 79 roll 41-45 timing.
On bigger tracks you can go as high as 84 roll Depending on the size of the track

don't use temps to gauge gearing or timing, base it on Punch & fade towards the end of the run, If its not fading much its possible you are not pushing enough.

Thanks. I'll start there with timing and get the gearing worked out
