I also heard it both ways on(to far apart/no problem) hi and lo bands...
Even tho my Dazzler was switched from hi to low and I've had no
problems, but it was a free plane.. I wanted to switch the rec. in my
Avistar from 51 to 23 and use the flight pack for my next plane... But
I'm still not sure what to do.. I've checked and asked but it's sort of like
a 50-50 thing... And the key thing here is.... A flight pack, or just the
rec. is cheaper than a plane.... But most if not all agree to stay with the
same brand for the rec....
