Does anybody have any performance charts or operating information for Raboesch propellers? Am looking for the rpm vs thrust relationship for the under 45m/m 3 blade sizes particularly, but anything would help. My traditional supplier cannot help and neither does the web site. Am trying to plan a future models and would like to be rather more scientific than the "if it fits it will work" approach or just using the motor O.D. as a guide to the propeller diameter.
Thanks Doug. Always thought, my old mathematics text books would come in useful! Was hoping for was a simple chart of speed vs thrust, recognizing there are many factors that influence them. Even a max speed and efficiency rating would help. R
