When will a kit be available??
Yhis is great for all RCers

On schedule to have them all finished by the end of this week.
you say larger ones....does that mean 80mm motors? or another version of your 63mm units? I am eching boards to hold the halls & wires in my v2 molds myself....your way ahead of me though.

I found on endless sphere that a lot of people use the S411A from Honeywell with 17,14° spacing so I tought to do thesame.
Below my temporally design of a bracket for use on my HK 6364 213rpm/V BLDC motor, I will be using the 150Amp HK car ESC.
I think of installing the mount at a distance of 3mm from the spinning motor:
like this the centerpoint of the sensors will be at around 4,5mm from the outside can of the motor...
Any remarks or ideas?
Maybe another sensor is better for this application?
Or other spacing?
Or another distance between sensor and motor?
(I have zero experience with adding hall sensors, BLDC motors or ESC, but I'll learn!)
Thanks in advance!
I might be interested in halls that can be mounted to the turnigy 80-100 series motor. But only if a mechanically untalented guy like me can acomplish the job . What is the price?

Going back a few years, at a brushless motor company we experimented with various types of commutation sensors on brushless motors. By some margin, optical sensors produced far better accuracy which a good controller can use to its benefit for switching phases. Hall effects, although convenient and cheap, have various drawbacks, some of which have already been highlighted in this thread (from the bits I did read).
For this motor, I would design an optical interrupter type arrangement which will work well. Of course, there are dust and environmental issues to solve. But still, for the performance advantage, I would chose this direction. With good shielding, you should be able to get something to work where marks on the spinning "bell" are being picked up by reflective optical sensors located around the periphery.
No, no, no, must resist, must resist! Too many projects!
