Yep. I don't want to leave the shaft and one way in there. If I'm going to be using a bump box anyway all those two will do is add extra drag. Oh, and once I get the back plate I definitely want to make sure its sealed. I know some companies sell RC engine sealant, but I'm thinking a bit of copper gasket maker will work just as well. Do you think that will work alright?
