I'm really afraid to turn the motor speed to 100% speed. :D Initially I thought you could simply control the motor for the test stand using the power supply. 

But I hadn't considered that RC motors draw a lot of current. At least with my laboratory power supply, the current limitation "already" turned on at 5A. To avoid this problem I just wanted to run the motor with a 2S LiPo battery. So that you can still set the speed, I got a PWM motor controller. (The 50W PWM controller I already had unfortunately desoldered itself during the first test.)

Thanks to the now available power reserves "upwards" I think that the Nerdiskerator can be tested well with this test setup.
