Yes I was surprised at the short life of the stainless brg. Guys here are reporting 300 or so on stainless. Don't know whether not changing the front bearing had any impact or whether the bearing was faulty. Will monitor the current brgs and see how they go. 45 flights so far so will pass the 60 benchmark pretty soon. Appreciate your comments on the head shim - is certainly worth a try. I presume that is 30-40 thou additional to the head shim as supplied
Cheers,
