I have a , strain gage, hanging style scale I bought to weigh planes and the larger parts of planes. I am wondering how well I can measure prop Thrust by looping a line around the tail of a plane on a hard smooth surface and applying power to the motor. The current Alpha 40 ARF test plane takes too little force to measure when dragging it along the floor. I expect static thrust is not the same as flying but would give me some comparible data. Any comments?
