Okay guys, I have heard about shaving off the webbing on the OS50 crank. My OS 50 works fine now except for the occasional rear bearing failure, but I dont want to do this mod if it will throw off the balance of the crank. I apologize in advance if this topic have been talk about already.
I will be tearing down my OS50 because im replacing the rear bearing with ceramics one. Since im there, I might as well do this mod. What do you guys think.

Yes, Wilson do the mod. I was planning to do mine but I hate to tear down my engine, also the Raptor 50Se is flying great. Maybe when I am ready to change my rear bearing I will do the mod then. Right now I have a gallon gone through it already and I will keep track of how many flight I get before the bearing wear out.

I read that Clarence Lee endorsed the webbing mod in his RCM Engine clinic column. Someone posted the text a while back.
