Propeller and Brushless Motor Test Bench
Description
I Had Big Issues To Find A Good Prop/Motor Combo To Built Quadcopter With High Efficiency Or High Thrust, Without Risking To Burn My Motors Or Escs. Because There Was No Prop Testbench Build Available And I Wanted Something Nice Looking Instead Something Built Of Wood Manually, I Decided To Design My Own 3D Printable Testbench. With This Setup You Can Use A Generic Kitchen Scale To Measure Propeller Thrust On The Bench. It Should Be Suitable For Props From 5 To 12 Inch (Smaller Props Could Have Issues With Airflow). I Designed This Thing As A Pusher Setup To Minimize Loss Of Thrust By Pushing Air Against The Frame. Length Of The Motor Side And The Scale Side Of The Arm Is Exact 150Mm From Turning Point So The Measurement Should Be Very Exact.
