I tried making a prop plane and when making the prop I had a problem as you can see on the pictures the lift vector are not all going in the same direction this causes my plane to go right or left.
If they were all in the same direction the lateral forces would cancel themselves and they would just be a forward thrust left.
the only way I had the vector symmetrical id when the blades are all flat perpendicular to the plane, all the vectors are parallel but when I throttle up it glitches and explode
If I turn the whole nose the asymmetrical vector will always stay in where there are in the photo, for example the two blades on the left are reversed if I turn the nosecone 90 degrees the reversed vector will stay in the same place.
I added a "Craft Side" option for wings so the player can override the automatic behavior of how airfoils are inverted. Now you will be able to just flip the Craft Side option so the lift vector is pointing the way you want.
