RE: 2.4Ghz Range Sucks
nimh AA batteries produce 1.2 volts per cell VS regular alkaline AA's which are 1.5 so for your RX that would be a 4.8 volts NIMH or 6.0 volts Alkaline, and the transmitter 9.6 volts NIMH or 12 volts Alkaline. Unless KO specifies to use Nimh batteries, I would switch to regular Alkaline batteries, 2.4 ghz systems can be picky with voltage and running nimh (fully charged even) in place of regular alkalines would be like running with dead batteries. hope this helps. Also may be worth checkin out throwaway lithium AA's from energizer which are also 1.5 volts per cell.
