Story

The existing motor tests benchs, thrust and power analyzer, are very expensive, I tried to make one at low cost, less than 30 €

In addition I created an Android application for the real-time display of the parameters:

Battery voltage

Rotation Speed

Thrust

Amperage

Power

I also wanted to make a simple fixing system allowing to test the various brushless motors or Electric Ducted Fan (EDF) with fast assembly and disassembly.

The test bench allows easy use of ESCs of different powers in order to adapt to the motors to be tested.

With this test bench you can choose your engine / propeller / ESC or EDF / ESC torque according to the characteristics of the aircraft you are building and check that the choice made will allow the aircraft to fly, you need a weight / traction power ratio greater than 1 and even 1.5.

The created application saves the data for storage and for later analysis

and the results

another test with two EDF and one brushless motor

a fine example of achievement by a pilot Mr. Mihály Váradi from Hungary Who compete in the free flight categories F1Q and F1B
