Perhaps you can use a different axle stub, like off of a buggy, so you can use a buggy hex? I know alot of the bones/stubs are interchangable. Like the LSP-Mayhem-LST ones...
I think Kyosho had a slip-on adapter for 14mm to use 17mm hexes
Edit: Found them but can't see them for sale on site. Part numbers are: MA058 for the slip-on hexes and MA059 for the washered nut to hold the wheel on
Work because i gotta, play because i wanna
People here hate Nitro, I love it. I start it, run it about 50 ft from me and it dies, I go after it. Perfect exercise
