Very nice clean build.. I too shared the bewilderment on the overly complex rear assembly when I had the FF03. Car handled like a dream and had much room for improvement from a 'lightweighting' standpoint. This car still runs toward the front of the pack locally in the rite hands.
Something about that IFS just makes it turn great. (comparing my FF03EVO to my FF04EVO)
I like how you mounted the servo and speedo more 'inboard'... awesome
