I would think that if you have the blade off center in the grip that you would change the way that the blade is loaded. If you do a FBD of it, you would see that you would introduce a vertical force on the blade root while it is in motion. I would assume that with the blade centered in the grip there would only be an axial load. Maybe I'm not seeing it in my mind correctly.....any one else have any thoughts?

If you take the example to an extreme and picture the blade mounted on top of the grip, you can see that as you change pitch, the blade will move fore-aft. As it moves fore or aft, its CG relative to the centrifugal force vector will also change, resulting in lead-lad shifts.

Will anything break, or even just fly like crap? Probably not. I've done it without any horrible results, but it was an molder fb machine turning relatively slow head speed.. Is it bad for bearings, does it mean more vibration, can it mess with gyros, especially fbl ones? Most certainly so. How bad? Probably not very.

I have done it before, didn't have any problems. It was not long term though, just until I could get some spacers shipped.
