oh yeah, Iforgot that part about the SLU (that it'll run the HL stuff, including the flash unit). It really is a sweet little unit, even if it is a tad complicated. I'm personally just waiting until it's completely Tamiya-compliant; until then I'm holding off. Though come to think, this set of circuits from Oz and the SLU pretty much act the same; no power drop-off with damage. So now the SLU has other systems that work like it, nice! Or uh oh-hopefully this doesn't mark a diverging trend in IRbattle systems! It'd suck to have to have two sets of tanks...
