Hello
I have a variable, going from 0 to 360 that make my chopper blades rotate:
When i set up the rotation manually it work
But when i use the variable not
On these screen you can see the numbers are right
Dunno what im doing wrong

Why not split the blades out as a separe mesh, add to the BP and make use of a rotating movement component?
Make sure your alpha is set to 1.
Your rotator might not have a normalized variable fed into it.
Thx but i found a workaround, im using add torque to the blades, wich is pretty usefull for the sound pitch i add to it, and i don’t have to worry about collision, about casting, or about doing it rotate slowly up or down
Why not spliting, because its easier to import on mesh and work with 1 skeletal, can have everything togheter
Here is the result : [video]https:///[/video]
Im using add torque with constraint, for both rotors
Pretty good. Nice audio.too 
Thx, i just added flap anims, blade air-resistance, hull air resistance, and know i don’t have to hard-pitch to move forward ( like in real-life )
Also i have to convert add force to add impulse, with tick delta because of the framerate.
Then i will realease it as open source for my open warfare project
