Hi all,
Maybe a newbie question but I’m not sure, in this tuning process when it said for MOT_THST_EXPO with props size the props size give is for diameter or radius?

Interesting question!
It also happened to me before by this confusion. The way I figured it out is trying to look that the props information for example 32-inch and measure it with the ruler. The result turned out, it is diameter!

Propeller sizes are named as diameter in inches.
