just got mine. i'd love to help you out and throw the rotor on the facts machine (and see for myself), but to be honest, i've never seen a design like this. i can't figure out how to take it apart and pull the rotor out. there's two tiny little grub screws at the end of the can. screws which i do not appear to have wrenches/drivers for (and i have several sets of the common metric and standard wrenches that are common for our hobby). so i'm stuck at this point...

This motor appears to be assembled similar to the Motiv MC3 and 4. Do not take out the two grub screws on the side, use a 1.5 or 2 mm wrench to loosen the three timing screws and rotate the end bell past the timing marks and the sensor should release from the motor. You may have to fully pull the three screws and the backshell to see how the sensor is keyed into the motor.

Hi all,
I just picked up a v21s 6.5t and can’t find any specs on it, anybody know what the kv rating is on this motor?

I would consider the Volta as a different product line than the V21S. The motor (21.5/17.5) definitely carries a different power profile than the R1 of similar winds.
The profile of the 21.5s tested on a load dyno, the Volta is RPM-based while the R1 V21S is Torque-based. Watts were a slight advantage to the Volta. Both had the long rotors.
The Volta is a great value for the price.

I ran the Volta in 17.5 TC at a big event in the UK and made the A final with it. Similar feel to my hobbywing G3R. This is the coolest running motor I think I’ve seen. It was a very large track and I geared at 3.9FDR and had timing at 52. I was pretty much on pace but there may be some tweaking to do.

your rotor measurements were similar to mine. on my fantom facts, the rotor was 1667/1668. not great. can't remember the last trinity rotor i measured that was under 1700. the last team powers rotor i measured was over 1740. also, the sensor board on the volta was the worst i've ever tested (44/46/51).
Fortuatnely we dont just race compoenants - although the sum of the parts might look better. Try it on a load based dyno. I do think it is probably two teeth less than R1 Ultra.

One thing I had to remember was that motor was not a full optioned version similar to the companies premium select motors.

The Volta is a great option at its price and will have every opportunity to gain improvement with more test and tune.
The R1 V21 series will continue to do well at every level as it has for several years now. Everyone can say they have faster motor but really, unless it is winning the big races where everyone is running top product - then it is all unproven.
R1 proves they can develop great product.
(I just run the stuff because it is rock solid, well built and developed by a solid group.)

when the couple race old team powers used motor i bought had more revs (4000 vs 3800), better sensor board (44/44/45 to 44/46/51), and a stronger rotor (1744 to 1668), i moved on and didn't bother to solder up the volta. yeah, we don't race components, but the volta's numbers were just too low in comparison to risk soldering it up, being disappointed and then having to sell it now as a "used" motor. i'm happy with the TP motor.
