First flight with the torque tube and the fin is buzzing. I placed the bearing on the tube according to the manual, but it looks awfully close to centered to me. What bearing placement works? I have extras to throw in there.

E820, Raptor G4N, X50F/E, E620, Forza 450, and some planks.

on my Raptor 90 3D I ended up adding one more bearing to support the torque tube. I marked the 1/3 points and just placed the bearings about an inch off the marks in different directions to not have equal lengths of torque tube between the bearings. Hope my description helps. Not fully familiar with the build of the X50.

That's about the way I did it with the X50E. Main thing is not to space the bearings evenly.

The X50 is single bearing, with the bearing holder placed 350mm from the tip of the nose of the shaft. This comes out to be very close to center.

So I should add another and space them such that I have three different segment lengths of torque tube?

I used two bearings to support the shaft.
