In the video attached I did a comparison of two flying wings that are similar in almost every way except weight and airfoil type. The white one uses KFm-2 and the red one uses KFm-4.
The videos shown side by side was shot within a few minutes on the same day so weather conditions was similar for both flights.
My conclusion is that the KFm-4 seems to be a lot more stable under the same conditions. This is just my opinion and may or may not be true for other types of planes, builds, setups or pilots.
So based on my own experience, my tip for any potential FPV49 builders would be to go for the KFm-4 instead of the KFm-2 if you want to have smooth and stable FPV video :)
