I have borrowed my friends stage 2 drag motor before. I ran it W/O the heat sink. It ran great for about 10 min. and then it seemed to slow down. I put my stock motor back in and it runs fine after 10min. W/O the heatsink. I haven't used a heatsink yet but the guy at RS said it was a must so you don't burn out motors. He also said that the Stage 3 motors "That will be out in Jan 04" come with an extra heatsink because they burn out with heavy use and loose their ability to disapate heat. I don't know how this is possible but I'm sure someone around here does. Good Luck, PEACE
