Huh? Greg can clarify his own meaning but I read his comment as “What does (RFM’s kit) bring to the market (of existing KTs by other manufacturers) that is not already here (i.e. available to modellers)?”
Dan’s witty riposte – (jeez do I really need to explain this?) that other KT kits don’t earn anything for RFM seemed to be understood perfectly well by 5 likers including myself. So - and remember you started it - who’s not too smart?
