The JR ProPo X2610 is a decent 72mHz radio and is likely a pre-cursor to the DX7.

Most of the DX7 programming instructions will apply.

Remember that 72mHz radios are not as noise immune as 2.4gHz, so fly in a prescribed area or club.

Also remember to grab the pin for your frequency so someone else does not utilize the same channel.... somthing that rarely occurs now-a-days!
