After the 2 successful and joyful Flights of my 3d printed Drumstick X470, the Mil Mi-2 RC Helicopter in my Yard, I went ahead to test the temperatures of ESC, Motor and battery using a SkyRC tiny Thermal Camera. I am happy to report that My special consideration to better airflow over Motor, ESC, battery and electronics keeps them cooler than expected, even though I flew it on a very warm morning (32-34 degrees centigrade) they stayed cooler. Flight performance was beyond my expectation. Watch full detailed build videos, a Closer look at the scale features I designed for this helicopter, maiden flight and more on my channel.
