Legally, we are not allowed to change the Transmitter crystals ourselves as it could throw the RF section out of tune and, perhaps, affect adjacent channels. Even though you can buy Transmitter crystals and physically change them yourself, you risk interfering with other radios.

You are supposed to send the Transmitter in and have it done by a technician who will retune the Transmitter.

The FCC authorizes 50 "Channels" for 72MHz use (in the range from 72 to 73 MHz) on RC aircraft, numbered 11 through 60. You can pick a different number in that range, and have Futaba switch your transmitter to that channel number and frequency.

There are other frequency ranges like 35MHz (common overseas, for instance) but the message you refer to is about channels 11 through 60 in the 72MHz range.

Best wishes,
