It doesn't matter how many blades you have, 2, 3, 4, 20 makes no difference. At some time the blade will be on the right side descending it will have an increased angle of attack and more pull.
The blades on the left side ascending will have a reduced angle of attack and will pull less. The blades don't have to be positioned opposite each other statically, they just have to enter the increase or decrease zone.
I mis-understood the question when I first read it, somehow I thought you were flying electric .
If you are, Gyroscopic precession may or may not have a noticeable effect, but it will have an effect.
A push down will cause the plane to turn left. A pull up will cause the plane to pull to the right.
Since this is not what is happening I think it might be P-factor not precession.
