update:
still trialing the 2413/14 twins.
The 2004 spec radio (PN2613) has been sussed out. I found a processor that will run with it. going to take a bit of fiddling but its definitely doable!!
experiments start once I get the processor here.
need to start on the 2005 version properly now. I'm going nutty looking at 4 schematics/ 2 chassis's at the same time.
Jon Chan,
expect a call on the white car in about a week. yours was one chassis I've modded, no stacker for it -YET.
