Neil is using drill motors which are 24v, 180w and about 2" in diameter and maybe 4" long.
My motors are 12v, 180w golf caddy motors with integral gearboxes. They're considerably bigger than Neils motors being 3" in diameter and about 7" long. They stay quite cool and probably don't need the cooling fans that are installed. I am going to try them at 18v over the winter to see how it goes.
