When I talked to Benny about what he would do differently on his build he said he would have made it so the top motor mount was removable, and I had those existing 450 pieces and wanted to figure out a way to use them, it turned out really well. The reason I am selling it is because my wife and I are expecting our third child any time now and I want to have a little bit of money saved up to help with bills and other things while my wife takes some time off work. I may build another one in the future though.
