Ron,

We measured the efficiency of the motor before and after surface grinding and found no measurable difference.

The first heat shrink housing was done with an aluminum shim to create the interference while the housings I fly with were made with the correct ID.

A stator heat sink design would still require a motor mount that had the rotor bearing bosses on it and a way to attach the stator to the mount. I like the current design for now.

The motors used on that electric Lazair did overheat.
