Thanks for all the replies. Just so I'm clear, I should be looking at a ground range somehwere over 100'. Is that with antenna retracted or extended? Also, just as a side note, I found the manual that came with the radio system to be very lacking. It said nothing about initially charging the batteries, range checking and a couple of other areas were a little vague. I would suggest that Futaba look at their manuals and take a little time to get a little more detailed.
