Hi Roger
As a Kyosho expert I wondered if you could help me. I have a RB6.6 slipper assembly on order to fit onto my Optima mid (but it’s on back order at the mo) doesn’t sit right with me fitting a Associated slipper on Kyosho as many have done. If I emailed you is there any chance you could measure the RB6.6 top shaft for me please.
My email is
