Some people have had a couple of issues with the new props. I tried them, and after about four flights, I started to pay attention, and noticed that my motors were running a weeee bit warmer. How much? Dunno, but when I used my cheek to check motor temps, they were noticably hotter, as I could not keep the motor touching my cheek. (No, not those cheeks!!!)
Went back to the stock props, and it seemed to "go back to nominal temps, I could hold the motors against my cheek and keep the motor touching.
So the "new" props went into the trash. Seems there is a dynamic between new esc's, and the new props, and the motors. I learned this when I built my heavy lift Tarot Hex, motors/esc/props are intertwined.....
