I figured you were busy with the upcoming races, etc. I'll think about
what you said.. I already include the mass of the motor with it's iron
and aluminum components the conducton of heat away from that and as well
as the conduction of the water tank itself. So I may be doing what y ou
suggest anyway...
Make em run fast and reliable Dave...
