this will take the centrifugal stress off the outer bearings.
I had one crash from a bad outer gip bearing; after doing this I've not had that issue (20+ flights). As well, it doesn't seem to affect the moveability of the blade grips.
I like this idea, since centrifugal force will hold the grips outward away from the hub, this really makes sense to me. Going to give it a try.
