have not been able to find the correct answer,

can i use my sensered mtr with a non sensered esc?

Yes. I think the only exception are some novak esc's. Most other sensored esc's can also run sensorless. which esc are you specifically asking about?

It depends on what you have.
I know it works with an RX8. My sensor wire came off once & it worked. Just not as smooth in low speed.

I have ran the Associated/XP Esc with sensored motors. (sensorless only ESC) they work but cog. 17.5 would suddenly stop, or brake. not m uch fun. tried a 13.5 it still did it, not as bad or often.

I have hear the lower turn number you go down, less cog affect.

In high turn counts, some sensorless ESC's have issues figuring out where the rotor is. So long as the actual turn count doesn't exceed the ESC's listed maximum, you should be able to run the motor sensorless without an issue.

Not so. In my slash, im running the vxl esc with a Tacon 7.5T 4800Kv motor and it cogs like a SOB at low rpm.

4800kv is a high turncount motor. By comparison, the 3500kv in my 'Pede does not cog much at all at low RPM.

Cogging is going to happen based on a lot of different things. It's pretty much all based on the ESC's ability to use the Back-EMF generated by the ESC to find out where the rotor currently is in a rotation.

In theory, the lower the turn count, the thicker the wire. The thicker the wire, the more pronounced the magnetic field set up when energized. And, all things being equal, when that field collapses (next phase fires), the Back-EMF generated will be larger, giving the ESC a better idea on where everything is, and as such, reducing the cog.
