RE: RC Surfer
Bear....
This style of stuffing tube / bearing combo is part of MJ's "Magic" Maui******** design. The only thing I'm tinkering with is cross drilling the removable stuffng tube bearing. MJ sweat solders the two together making replacement possible.
I saw these cross drilled bearings on HobbyKings site, but I fabracated one up myself. I'm hoping for better grease retention in the all important bearing surface.
