I decided I wanted to go with a 1:8 sensored setup for my new 1:8 truggy. I ordered the Turnigy Trackstar 2100kv sensored motor. I thought that it's a shorter and fatter 4270 can, with 4 poles for better efficiency, and I would be happy to take a punt on it for £42. I figured I could get it up and running with an old sensorless HW150 I have lying about somewhere, and then move up to sensored mode when I choose a sensored ESC that's good for 6S.
Anyhow, I looked at the options for a 150A 6S sensored ESC on Hobbyking, and the high performance sensored version of the HK150 they have which can do 6S.
Turns out the ESC can't handle 4 pole motors in sensored mode. Without the sensor wire they are fine, but it says running sensored 4 pole motor will end up with bad things happening. They have another 150A 6S ESC which can run sensored motors, but it says nothing about the 4 pole restriction.
Both are out of stock
I never heard of an ESC that couldn't handle a specific motor pole configuration like this before. My other choices for ESC are the HW Xerun 150A sensored ESC
or the very similar and slightly cheaper Skyrc Toro TS 150A.
Can anyone vouch for 4 pole sensored operation on any of these ESCs?
