Thanks scratcher, I have looked at the D4 and have found it for £119 4wd, less for rwd. Looking at this though it seems to have everything that you would hop up on the sakura chassis. It looks like you could get spares from the major players to fit it, hopefully. The TD10 I bought has next to nothing unlesss you really look and go into dimensions etc. and then you realise you can actually use mst, kokomo etc parts.
