The larger the rotor, the magnet in the rotor moves closer to the stack/winding, thus more magnetic pull to each poll, while just the opposite with a smaller rotor.
My SPX quit working properly, does not do the accelerated timing on profiles 6, 7, and 8 anymore, and instead works almost like a normal sphere now. Anyone else experience this?
I have read on a few other threads where the SPX looses profiles 6, 7, and 8 after awhile. Some SPX drivers are replacing their speedos quite often because of this. Have you tried your SPX with another motor and had the same effect (loss of profiles?) Could this be a heat issue over time that makes this happen? I'm wondering if running the heat sink on the ESC would keep this problem from occuring. Just trying to gather more data on how this happens so that it can be avoided in the future.
