Hi for my master thesis aviation engineering at VUB. I have to make a test bench for scaled blades of a helicopter.
I'm using a Turingy 500 H3126 brushless outrunner 1300KV with 600mm blades. To be able to test for longer periods i have installed a DC power supply in stead of a battery (the helicopter is mounted to a test bench). The supply has a rated current of 60 amps and a max voltage of 14V. In theory this should be enough to power the helicopter, but when i increase the angle of the blades, the rpm decreases. So my question is; where is the problem? And could the ESC have anything to do with it? I use a red brick 70 amps.
Could anyone help me?

kind regards

Cathal
