Inductance is in milli henry usually, but it is not super important to measure, as long as you get a top quality motor(like the R1).......

Anyone have a starting point for rollout in 17.5 1/12 with the v21?

I'm also having a weird issue, that the motor spins the opposite direction of all my others...so I swapped the direction in the esc and the motor won't turn unless I give it a spin by hand and then it gets hot very quickly. Anyone else run into this?

Good to know - glad it should be a simple fix! Hoping for no issues when I send it in for warranty since it hadn't even seen a lap yet.

Finally got to practice some with new 21.5 V21 with torque tuned rotor and it was very good in my A800XA USGT. On a dirty black carpet with the exact same layout as our last big race, I was able to turn a 10.0 versus a 9.9 which was turned on clean high grip black carpet.

Just the opposite, I've found them to be quite durable compared to most.

21.5 TC, VTA - v21

Anyone running 21.5 TC with v21 - how is the motor compared to v16? worth buying new motor?
Same for VTA - significant difference?

Timing for the motors?

The guys at the track that have tried it so far aren't liking it. It draws too much current and the rotor goes soft too easily. Maybe they haven't dialled in the right settings yet.
