Xpressman - I believe the Hacker system is sensorless (which the rules allow), so it wouldn't rule them out. (I thought we all tried to AVOID racing against hackers??
) They list their motors as having 7 or 8 turns, not 7-1/2, so I don't know if they're wound as a "Y" or a "delta".
Not subscribing to the conspiracy theory, I think they specified the sensor connector details to CREATE an industry standard, which would make it possible for a motor builder to make motors to run on anybody's "sensored" ESC, and ESC makers could connect to anybody's sensored motor. This way, a company could compete without having to build both motor and ESC. None of this really mattered when all we had was 2 wires, but now it does. Imagine how bad it would be if 7 different brands chose 7 different connectors, pinouts, polarities, etc. It's bad enough now that speed control manufacturers have to ship 3-4 different hoods for the receiver plug.
5-pole motors? Sounds like the old Astro-Flight ones, which I think had (illegal) cobalt magnets. Personally, I think we already see too many motor design variations with minimal benefits and maximum hype. Unless someone can find a way to get 10% more efficiency or 10x brush/comm life, I say leave it alone. (Cobalt or rare-earth magnets might just be a worthwhile change.)
