Was doing a little research. Noticed the 2 bearings in each grip are part number pv0175/HMV1680 with a dimension of 8x16x5. Comparing this to other TT helis, nothing else comes up under a parts search. However, I noticed the R30V2 heli pinion HMV1680ZZY bearing ,which is in bearting set pv0093, is the same dimension of 8x16x5. Are these indeed the same bearing, or doe the "ZZY" extension mean something else? Just thought this would be good to know incase a grip bearing was ever needed and an R30 pinion bearing was lying around.
