My manual may be different because it says the IBU2 supports the Tamiya apple but that's all. No installation instructions or wiring diagrams, but all I have to do is email Ian (my supplier) and he'll send whatever info I need to make the hook up. The important thing is that I know the board is set up for it so the rest is just a case of getting it installed. When the time comes I'll investigate further and if it looks like the best option I may try out the IR emitter socket and the Tamiya base from Battle Armor. I also got some new IR emitters from digikey that Kevin recommended, and they're supposed to be the best thing going at the moment (we all know how fast that can change!).
But ... the new Clark Package is supposed to be here today so guess where
my mind is right now!
