3D model description

I wanted to test a new combination of a motor with a propeller. Then I found out that our kitchen scales could do it. It shows not only a weight, you can also pull up the scale pan because it is bonded to it. So you can measure the thrust in both directions.
It is possible at least with the "SOEHNLE" max 2000 g - if you have it by chance.
You need also a square tube 20 x 20 mm to fasten your test part with screws M3.
For testing my impeller you can fasten the housing with the "bracket for impeller".
The second part of the video shows the test with the Roxxy Outrunner and a propeller 10 x 6" driven by a 3 cell battery. We measured the thrust, current flow and the temperature. Unfortunately we documented only the temperature. Anyway, the temperature is important if you use PLA to mount the motor. We reached 68Β°C residual heat - I think the nose should be better printed in ABS ;-)

Attention
If you use it by thrust upwards, make sure that the scale pan is tight bonded and charge it more than the possible thrust (such as machine vice). Otherwise it will morph into a uncontrollable helicopter ;-)
Please proceed carefull and be aware that you will use it on your own risk.
