you're right Gaston, the two blades generate a stronger counter-hit, when the blade is in the base position, its seems to help, in the workshop when I have powered the engine with the blades to install it gave good results at high speed, no vibrations, but a slight oscillation of the nacelle. which is a little more important when the blades are fixed without the possibility of turning. And it is not intended for a very high speed of rotation.
