I found a fix for the blade grip bearings

My LHS didn't have the trex250 bearings so I had to improvise...

take the two brass washes in between the blade grip inner bearings and the head in the middle, and put them on the end of the feathering shaft just under the screws
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.
