Default UFO brushless motor

Interesting, besides what looks like a limited timing range, reversing the connections and sensor location makes a lot of sense. That has to keep a noticeable amount of weight more inboard with the wires routed too it and all.

It would be nice if the timing marks were visible with the motor installed. As it appears, you would need to remove the motor to adjust the timing accurately.

There was a guy here who was posting most of last year about testing these. Seems that the originals had fans in the rear endbell, but that wasn't working out too well. I wonder if they kept that design feature.

Look close and you can see the vanes for the fan through the holes in the endbell. That needs to go if they want a good motor.

Yep, clearly on the blue one. Between the fan and the inability to see the timing when it's installed, I'd say it's a blind alley. I think that the sensor plug is going to play havok with some of the top decks that overhang just over the motor, too!

Not enticing at all unless they perform like nothing I've ever seen.

There is no reason to expect performance increase from the design, especially if built to roar specs, there is only so much that can be done. It's a form factor and possibly weight balance advantage, so subtle, but it seems like many are putting a lot of effort into getting low CG and centralized weight these days.

I would also think they could etch timing marks into the top of the can, so you can loosen the outer screws and adjust it without removing the motor.
