RE: Futaba High Band / Low Band
If Futaba gets you to buy an extra RX with a perfectly good one sitting on your shelf, then they have done their job, which is to increase sales. If it is important at all why doesn't JR do it. Futaba correctly assumes that if you have a 1000 into an heli or airplane whats a few more $ to make sure you have that extra bit of insurance. Good marketing.
