Hi, I'm looking for a device that can collect data from a Motor and a Propeller, running at a duty cycle corresponding to the range of a motor's voltage, to measure and analyze the following parameters:-Propeller RPM-Current Draw-Lift GeneratedAnd from there, can calculate:-Thrust Generated-Power Input-Power Output-Motor efficiencyAnd probably other ratings too. I've looked and can't find anything that could be used for the physical part of this concept, so I've attached a couple ideas.The hard part to me in this is the actual physical construction. Removing friction and inertia to negligible quantities and being able to measure lift accurately will be a challenge. Any input is appreciated.
