So if I do a build using Richard’s and Comfychair’s FET driver with the Oshpark 3XML designed by Scaru the difference in time that I can run it on high before it’s too hot to hold versus a more ideal copper star with direct thermal path will most likely seconds? Unless Richard comes up with a copper spacer for the S6, I’m thinking of a home rolled P-60 in a Solarforce. Ala dorpmuller -if that helps visualize thermal capability. Thanks for any input or suggestions.
