I'm pretty sure most of the support is on their facebook page.

I emailed them about getting an invoice for a sensor board replacement. Email response was quick and easy. They have their contact info on their site towards the bottom

I have one of the "Hand Picked Rotor, Aligned Sensor" motors, and it's a weapon. Should I adjust my timing as normal when tuning the car, or leave it as set by the OEM?

The timing set from the factory is based on a safe setting that is made so as to not damage the motor. If you have a tuning method you should use that.

The last R1 motor I bought came at a setting that drew 9A under no load. It was not particularly safe.

I知 running a 25.5 v21-s in my F1 currently geared at 86 spur 32 pinion on high grip black carpet. The timing is about 46* on my Motolyser. Down the straight I can keep up with the faster drivers but in the infield they just pull away from me. Fast guys lap times are low 12痴 I知 mid to upper 12 second range. Am I over geared? Am I under geared? Please help

sounds more like car setup rather than motor. You could be scrubbing speed in the corners. You could always drop a tooth on the pinion to see if you gain a little in the infield.

I agree on that one. Sounds like the other guys are pulling out of the corners faster, so you need more torque.

I'm looking for some help on this as well.

I'm running on asphalt as well, our straight is about 80 feet. I'm using a 3racing Cero Sport, it has a 1.9:1 gear ratio. Traction is mid-high

Recommend starting around 3.4 fdr for 21.5, and 3.8 to 3.7 fdr for 17.5. Timing should be set to 40* on the endbell. I wouldn't ever exceed 42* on the endbell, the v21s doesn't like a lot of timing so 40 is usually the sweet spot. Most of the tuning should really be with the gear rather than timing. If you have a good fan on the motor, temps around 180* are fine. The big thing is that the motor cools down quickly after the run, so keep the fan running while you turn marshal. The v21s stator can easily handle this.

Appreciate the feedback but I have to ask. Is that FDR correct for 21.5? Right now, I'm running 101x41 with a transmission ratio of 1.9:1. That puts me at 4.68 FDR, getting to 3.4 would be a significant change in gearing.

Obviously your recommendations are for a two cell application. Do you have any single cell experience you would share?

4.68 on 101x41? That seems very under geared or your motor is unusual. On my R1 shorty 21.5 I was around 3.8 on a 90x40 carpet track.

Your ratio is roughly what I'd be running with a 13.5T motor on a large outdoor track. At the very least I'd be dropping down to 3.8 FDR for your sized track with a 21.5T. 3.4 is where I'd start for 21.5T on a larger track.
