ZMX FinX30 2600kv - Discussion

All information in this video is as a result of discussion with the designers. I cannot confirm any part of it and as some have pointed out below, there is no Halbach effect going on here but the flux ring is doing something special for sure:
These motors do not employ a true Halbach array. It's a pseudo Halbach array induced by the flux ring (or so I've been told). I apologize for not making that more clear.
Demonstration of a Halbach array effects:
FinX23:
FinX30:
FinX40:
1500KV:
2600KV:
The 23 is the race motor.
The 30 is the acro/race motor.
The 40 is the endurance motor.
