RE: Shuttle+ blade grip bearing fit
I ordered up a brand new set of blade grips from MRC and the bearing fit is perfect and snug. In fact the bearings go in with a snug pop! Much better than the earlier batch Shuttle plus blade grips I bought on Ebay some time ago where you could actually see the movement of the outer race in the bore with your naked eye. I fitted my ZX with the new grips, fresh bearings and thrust bearings. MUCH more responsive to the collective and cyclic controls now. Too much drag on the outer bearing with the original ZX holders since I'm turning about 1800+ on my head speed. Did my first loops and rolls this last few weeks and the old Shuttle is pretty well dialed in now.
Everyone who see's the Shuttle fly comments on how smooth it is!
