For my university project I am calculating the performance of a UAV however I am struggling to calculate the dynamic and static thrust produced by a prop. Which leads me to a couple of questions... 1) When calculating the thrust of a motor with a prop, how do I determine the RPM of the motor...

any calculator tools to optimize propeller size for "found" electric motors? I was thinking about scratch building an aircraft, and using a pair of Dewalt 60v FlexVolt 7 1/4 cordless saws for propulsion as they report the motor produces 1600 watts at 5800 RPM, but I am not sure of the...
